Role of Yoga based stress management program towards leadership development in managers

Billions are spent in the west as well as in the east for leadership programs. The question also arises what kind of strategic interventions are really effective. Till date a specific model is not available to answer the above queries. With this back ground, the present study aims to find out how far the Yoga intervention has brought transformation in leaders. A five day Self Management of Excessive Tension (SMET) program, based on the five layer model espoused by yoga theory and is believed to facilitate improvements in qualities required in leadership development. Multi-factor Leadership Questionnaire (MLQ) was used for assessment of 62 managers on Oil and Natural Gas Corporation. A significant improvement (p<0.05) in the attributes of the managers is observed in the pre-post results. This empirical study can be a solution and could introduce a new paradigm in the

Technology Focus: Production and Facilities (December 2012)

Technology Focus Commissioning and startup of major oil and gas projects is a project in its own right, running in parallel with the main project. It requires years of advance planning. The management and detailed planning of this phase are crucial to the smooth transition from construction to operation. There are several reasons that, in recent years, the commissioning and startup phase is becoming more challenging. The size, complexity, and costs of projects have increased steadily. Facilities costs now represent a substantial amount of the development costs. For example, for a typical new onshore development in the Middle East, the total investment costs are roughly split equally between drilling and facilities. More stringent environmental regulations and the increased emphasis on safety and automation have also contributed to making startup more challenging. The industry needs to learn from past experience to continuously improve performance of megaprojects. A recent study of major industrial projects by Ed Merrow of Independent Project Analysis was published in the April edition of SPE’s new bimonthly magazine, Oil and Gas Facilities. It showed that oil industry megaprojects fared very poorly compared with nonexploration and production (E&amp;P) projects. The study found that the majority of E&amp;P projects were schedule driven to minimize the time to first oil. It noted that “the drive for unobtainable speed to first oil is crippling the industry.” Because startup is the last phase of the project, there is little margin for schedule slippage. To shareholders and management, the all-important date of first oil represents the turning point in the project cash flow. All parties—project team, contractors, and vendors—are under immense pressure to meet this date. As the industry moves into deeper water, commissioning and startup of offshore and subsea facilities requires special attention. Earlier this year, the Norwegian classification foundation Det Norsk Veritas (DNV) published a new recommended practice, DNV-RP-A205. This publication gives the best practice for commissioning topside process facilities in mobile marine units such as floating production, storage, and offloading units. Precommissioning and commissioning of subsea production systems is addressed in American Petroleum Institute Recommended Practice 17A, which is also International Organization for Standardization standard 13628-1. In reviewing papers for this month’s feature on production and facilities, more than a dozen papers contained the words “commissioning” or “startup” in the paper title. I hope the selected papers, as well as the ones listed for further reading, will give readers an appreciation of the complexities associated with the commissioning and startup of major oil and gas projects in different parts of the world.

Wavelet Analysis of Geophysical Well-log Data of Bombay Offshore Basin, India

Geophysical well-log (bore-hole) data facilitate understanding of the physical properties of the subsurface formations as a function of depth measured in a well. In the present study, the wavelet transformation technique was applied to the well-log data of three wells in the Bombay High oil field, India, in order to identify depths to the tops of oil and/or gas formation zones (pay zones). Continuous wavelet transformation (CWT) was performed on gamma-ray, resistivity, neutron porosity and velocity log data sets in order to determine the space-localization of the oil and/or gas formation zones. The choice of a mother wavelet is important and largely depends on the data under investigation. We have applied a variety of wavelets to the different log data sets to not only identify the depths to the tops of formation zones, but also to determine the optimum wavelet that best characterizes the pay zones. On examination of scalogram plots of each log corresponding to each wavelet for their better resolution in identifying the formation boundaries, we have found that the scalograms corresponding to the Gaus1 wavelet appeared to give the best resolution in identifying the depths of pay zones in all the well-log data sets of all three wells. To further validate the above observation, a histogram analysis of CWT coefficients is made. This showed that, of all the wavelets considered for the present study, Gaus1 wavelet is the most appropriate and optimum for determining the space-localization of pay zones in all the well-log data sets considered in the present study. The depths of pay zones estimated from scalogram plots of logs agree well with those provided by the Oil and Natural Gas Corporation Ltd., India.

Public Policy and Setting Aside Patently Illegal Arbitral Awards in India

The Indian Arbitration and Conciliation Act, 1996 was enacted for the purpose of making the law of dispute resolution in tune with the international economic scenario. The Act was hence modelled on the basis of the UNCITRAL Model Law on International Commercial Arbitration, 1985. The Model Law was based on the philosophy of limited grounds for setting aside arbitral awards at the legal seat of arbitration and the grounds are almost identical to those of the New York Convention for refusal to recognise or enforce foreign awards. The same philosophy was adopted in the Indian context under Section 34 of the Act. One of those grounds is public policy, by virtue of which, any award rendered by the arbitral tribunal that is contrary to the public policy of India could be set aside.Initially, the courts in India interpreted this ground of public policy in a sumptuary manner, in consonance with practice in various countries. In Oil and Natural Gas Corporation Ltd. v. SAW Pipes Ltd., however, the Supreme Court broadly read the ground of public policy to the consternation of many lawyers and stakeholders of the arbitral process.The reason for their anguish was that in SAW Pipes, the Court held that an award could be set aside if it was patently illegal. The SAW Pipes decision has been criticised for subverting the arbitral process and for being in contradiction to the policies contained in the Act, especially the policies of finality of awards and minimum judicial intervention into the arbitral process.However there are many who argue in support of SAW Pipes for expanding the notion of public policy and specifically for reading patent illegality into public policy. The supporters of the latter view argue that commercial arbitration cannot exist in the area of lawlessness and the arbitral award should not be free from scrutiny. The legal fraternity has argued either for a broad notion of public policy without giving due regard to the promptness of the arbitral process in dispensing justice or for a swift arbitral process without due regard to the role of public policy in the arbitral process. Placing this issue in the form of a dichotomy leads to problems. Hence, this paper attempts to (1) find out what are the merits of having a broader notion of public policy in connection with setting aside arbitral awards, as contemplated by SAW Pipes; (2) look into the possible problems that could crop up because of a SAW Pipes type reading of public policy in Section 34(2)(b)(ii) of the Act, especially the effect on the finality of arbitral awards in an era of globalisation; and (3) find out if the problems created by a wide reading of the term public policy in Section 34(2)(b)(ii) could be eliminated.

‘Social Issue Is Business Issue’

The Management Centre for Human Values (MCHV) along with the participants of the Post-Graduate Program for Executives (PGPEX) and the Oil and Natural Gas Corporation Limited (ONGC) on the occasion of the Golden Jubilee of the Indian Institute of Management Calcutta (IIMC) arranged a seminar on Socially Conscious Leadership, or the Lattice 2010, on 19 December 2010. The seminar debate on the role of Corporate Social Responsibility (CSR) in contemporary business makes for an interesting note that would befit the Journal of Human Values (JHV). This is so because the invitees to the seminar, through their singular and idiosyncratic narration of experiences, have inevitably problematized the basic concepts of CSR itself. Concepts like ‘human values’, ‘ethics’, ‘social consciousness’ no longer exist as water-tight compartments of traditional or even autonomous sanctuaries of humane goodness. These concepts have been transformed from ‘value-adding’ propositions to ‘value-appropriating’ propositions, or in other words, social issues have become business issues. A wide spectrum of views coming from Gen. Bajwa, representing the army; Prof. Chaudhuri and Prof. Bhatta, representing administrative academia; Sri Salvi and Sri Tyagi, endorsing real-life CSR; Mr Ahir and Mr Rayaprolu, representing the corporate; Ms Vatsa and Ms Swami, representing NGOs; and Prof. Sarkar, Prof. Mohanty and Prof. Chatterjee, representing the academicians; along with the presence of Ms M. Bhattacharya from ONGC—all of them have aided and abetted in establishing the contemporary position of CSR as a successful and competitive business proposition. The note addresses the issues developed from their individual experiences and opinions, and attempts to establish, but on an individual level, an intellectual point of departure for an academic discussion of CSR that would initiate further potent research and theorization in this regard.

Radiocarbon evidence of paleo-recharge (pre-Saraswati period) of potential deep aquifer in Thar desert

The Oil and Natural Gas Corporation Limited (ONGC), India, embarked upon exploration and exploitation of deep groundwater under the project named as “Saraswati” in arid Thar desert, Rajasthan, with a societal mission of providing water to the local people and cattle. A 555 m deep well drilled by the ONGC near Jaisalmer town in 2006 encountered a potential aquifer at a depth of 450–500 m. Radiocarbon dating of this well water indicated paleorecharge to be >40,000 yr BP (uncorrected) (Before Present with respect to 1950 AD), while the medium depth (∼200 m) well waters around that area showed an age range of ∼9,000 to 17,000 yr BP (uncorrected). These waters represent pre-Saraswati era recharge, because the mighty Saraswati flowed in this region between 7000–4000 yr BP. The stable isotope (δD and δ18O) and Total Dissolved Solids (TDS) data of these waters clearly indicated absence of communication between the two aquifers (deep and medium depth). However, the extension of this deep aquifer needs to be determined.

Evaluating boards of directors of public‐sector companies in India: An empirical study of India's Navratna companies

AbstractThe Navratna companies are a group of Indian public‐sector enterprises to which the Indian government has given a measure of financial and operational autonomy that allows them to make investments without the need to seek government approval. Evaluations of the operation of the board of directors of the Navratna companies are, at times, complex and confidential. This can make studying, analyzing, and evaluating them a difficult task. This research is based on a survey of the board of directors in nine Navratna companies: Oil and Natural Gas Corporation (ONGC), National Thermal Power Corporation (NTPC), Steel Authority of India Limited (SAIL), Indian Oil Corporation (IOC), Hindustan Petroleum Corporation Limited (HPCL), Bharat Petroleum Corporation Limited (BPCL), Gas Authority of India Limited (GAIL), Mahanagar Telephone Nigam Limited (MTNL), and Bharat Heavy Electricals Limited (BHEL). The results of our survey provide the basis for the evaluation of the operation of the board of directors of Navratna companies. They also indicate that the board of directors should not involve itself in the day‐to‐day functioning of the organization and that governance of such companies involves more than simply ensuring returns in the short term. © 2011 Wiley Periodicals, Inc.

An Ultradeepwater Heavy-Oil Development Offshore Brazil

This article, written by Assistant Technology Editor Karen Bybee, contains highlights of paper OTC 20537, ’Parque das Conchas BC-10 - An Ultra- Deepwater Heavy Oil Development Offshore Brazil,’ by K.H. Stingl, Shell International E&amp;P, and A. Paardekam, SPE Shell Brazil E&amp;P, originally prepared for the 2010 Offshore Technology Conference, Houston, 3-6 May. The paper has not been peer reviewed. Parque das Conchas is an ultradeep-water heavy-oil development in the northern Campos basin offshore Brazil. The project is a joint venture between Shell, Petrobras, and Oil and Natural Gas Corporation of India. The first phase of the project is the development of three independent subsea fields tied back to the centrally located turret-moored floating production, storage, and offloading (FPSO) host facility, the FPSO Espirito Santo. Introduction The Parque das Conchas development grew out of a substantial exploration and appraisal program beginning in 2000 in which 13 wells were drilled and six discoveries were made. The Declaration of Commerciality was signed with the Brazilian National Petroleum Agency in December 2005, and the project was sanctioned in November 2006. The four main reservoirs—Ostra, Abalone, Argonauta B west, and Argonauta O north—were named after shellfish indigenous to the area. Together, they form “Parque das Conchas,” or “Shell Park,” in Portuguese. This is the first project in Brazil taken by Shell from exploration discovery to production. First oil from Phase 1 was achieved on 12 July 2009, just 9 years after discovery. Development Abalone, Ostra, and Argonauta B west are small-to-medium in size and stratigraphically complex, with highly faulted, compartmentalized, unconsolidated sand packages. The reservoir pressures are low, and the oils range from heavy to light, ranging in gravity from 17 to 42°API. A fourth heavy-oil field, Argonauta O north, will be tied back as part of Phase 2 and is planned to be ready for production in 2013. The Argonauta O north field contains 16°API oil and will require waterflood for reservoir-pressure support. The Phase 1 subsea infrastructure consists of 10 producing wells and one gas-injection well connected by 100 km of insulated and uninsulated flowlines ranging in size from 6 to 12 in., 15 flow-line sleds, two production manifolds, two artificial-lift manifolds housing a total of six vertical subsea-separation caissons with 1,500-hp electrical submersible pumps (ESPs), and 25 rigid jumpers, all of which are serviced by approximately 30 km of multicircuit high-voltage electrohydraulic (HVEH) umbilicals connected to the FPSO. The gas is processed on the FPSO, and to avoid flaring and to reduce CO2 emissions, it currently is being injected into a gas-injection well. A dedicated 40-km-long 6-in. uninsulated Parque das Conchas trunkline has been installed from the FPSO and will be tied into the Petrobras Caipixaba gas-export pipeline at the Petrobras BC-60 location scheduled to be operational in 2010. The oil is stored on the FPSO and offloaded to shuttle tankers as required.

Techbits: Conferences Highlight Indian, North African E&amp;P Efforts

Techbits Two conferences held recently highlighted the challenges and opportunities unique to E&amp;P activities in two important oil and gas regions, India and North Africa. SPE Oil and Gas India Conference and Exhibition (OGIC) The SPE OGIC, held in January in Mumbai, had an overarching theme of “E&amp;P Business: Excellence Out of Turbulence.” The event, which marked the first conference organized by SPE in India, brought together more than 1,200 industry leaders representing 167 companies from 30 countries to discuss new means of managing risks at times when oil prices undergo wide fluctuations. To open the conference, Murli Deora, the Government of India’s Minister of Petroleum and Natural Gas, sent a message that included his best wishes for the conference’s success and emphasized its importance to the region. “We need to deploy our best brains to find technologies which can bring [oil and gas] resources to the realm of affordability and sustainability and at a scale which would aid in furthering the region’s economic activities,” Deora said. “There is no single solution. There is no single company, nation, or technology that can meet our energy challenges, all on their own. Sustainable energy solutions would require increasing collective attention and efforts.” Following the inauguration of the event, a VIP tour of the venue and exhibition space took place, which included dignitaries R.S. Sharma, chairman and managing director of Oil and Natural Gas Corporation (ONGC); Sudhir Vasudeva, OGIC chairperson; and 2010 SPE President Behrooz Fattahi. Several of the 30 companies exhibiting at the conference launched new products, including new rotary steerable systems designed to create smoother wellbores and new multiphase-flow measurement devices that do not require separation of fluids. An executive plenary session followed, in which panelists including N. M. Borah of Oil India, Derek Fisher of BG India, A.K. Balyan of ONGC, and James McCallum of Senergy shared their regional and international insights on how oil and gas companies are committed to exploring more efficient methods and integrating advanced technologies to enhance their operations and improve productivity. The first day also included several technical sessions that explored E&amp;P topics such as well simulation, unconventional-resource extraction, reservoir characterization, facility engineering, and drilling challenges. The day closed with a special session titled “Management of Mega Projects,” which addressed the optimum ways to design and manage mega E&amp;P projects, to reduce their intensive capital investments, and the best strategic approaches to improve a project’s overall management process.

Harvesting Oil in India's Rajasthan Desert

The Thar Desert in India’s western state of Rajasthan is a desolate region characterized by wind-blown sand dunes. The state is a major tourist attraction, drawing millions of visitors annually to tour forts of medieval kingdoms and visit camel fairs. It is here that Cairn Energy, a Scottish oil company, took over a production-sharing contract (PSC) from Shell in 2003 and developed a major oilfield that has recoverable reserves of at least 1 billion BOE. The major oil companies have conducted little wildcat exploration in South Asia. From 1980 to 1991, the majors drilled 8,000 wells in Southeast Asia, but only 12 in South Asia. Indigenous exploration in Rajasthan began with an inconclusive exploration attempt by the government of India in 1955. In 1988, Oil India discovered natural gas near the town of Jaisalmer and has been producing 0.6 million sd m3/d since 1996. Floated on the London Stock Exchange in 1988, Cairn Energy first entered South Asia by signing a PSC with the government of Bangladesh. In 1997, during a swap of properties with Shell, Cairn acquired a 10% interest in the Rajasthan PSC, which Shell had initially signed with the government of India in 1995. The PSC covered block RJ-ON-90/1 consisting of an initial area of almost 12 000 km2—3111 km2 is now included in the development area, with India’s public sector oil company, Oil and Natural Gas Corporation, holding 30% ownership. After the discovery of the Guda field in 1999, Cairn increased its participation to 50% and eventually took over Shell’s remaining share in 2003 at a cost of USD 7.25 million and became the block’s operator. “Drill Till You Drop” Strategy The geology of the block in Rajasthan’s Barmer basin consists of channel sands stacked on top of one another to create a fluvial reservoir that has high permeability (1–25 darcy) and high porosity. From 2004, Cairn adopted a “drill till you drop” strategy. In January 2004, the company made its initial Mangala discovery with the 16th well in the basin. Following the drilling of appraisal wells, 3D-seismic-data analysis, and well tests, Mangala was confirmed as the largest oil discovery in India since 1985. The Mangala reservoir has a 150 m oil column of medium gravity (20–28°API) viscous crude (9–17 cp) with sulfur content of about 0.1%. The crude has high paraffin content that makes it suitable as a secondary feedstock for refineries, but pipelines and trucks carrying the crude require heating and insulation. Up to 2005, the company drilled more than 140 wells in Rajasthan with a yield of 25 discoveries. In addition to Mangala, Cairn’s major discoveries are Bhagyam and Aishwariya, with 22 other fields including Guda, Saraswati, Raageshwari, Greater Raageshwari, and Kameshwari. In August 2009, the Prime Minister of India, Manmohan Singh, joined Cairn Energy Chief Executive Bill Gammell in inaugurating oil production from the Mangala field.

Adapting to Shifting Government Priorities: An Assessment of the Performance and Strategy of India's ONGC

The state-owned company Oil and Natural Gas Corporation Limited (ONGC) is India’s largest company devoted to exploration and production (E&P). This paper attempts to unpack the dynamic of the government-ONGC relationship. Focusing specifically on how government ownership and control has influenced ONGC’s performance and strategy, this paper makes four main arguments. First, ONGC exists, just as with national oil companies in many other countries, because of a legacy of suspicion about outsiders. It performed well when it was tasked with things that were not that difficult and when it had help for the more difficult ventures, such as frontier E&P and development. Second, ONGC has run into trouble as it matured, and the roots of its troubles are mainly in its interactions with the GoI and secondarily in its management. Third, a slew of reforms instituted since the mid 1990s have fundamentally changed the landscape of the E&P sector in India and the dynamic of government-ONGC relationship. Targeted at improving corporate governance, enhancing competition in E&P, and eliminating price controls, those reforms have had a mixed impact on ONGC’s performance and strategy. They also highlight the difficulties the government has had in encouraging higher efficiencies in ONGC and the oil and gas sector. Fourth, given the deep interconnects of the oil and gas sector with India’s political economy, fixing the oil and gas sector essentially entails fixing the larger political economy within which the sector is embedded.

India's First Deepwater Offshore Field Showcases Ingenuity

India’s first deepwater oil and gas field, located in the KG-D6 block 60 km off the east coast of India in the Bay of Bengal, is a success story of government initiative, private enterprise, and global engineering ingenuity. Operated by Reliance Industries, a multinational corporation based in Mumbai, KG-D6 is a world-class discovery at 1200-m depth with proved plus probable reserves of 11.3 Tcf. The fast-track construction of the oil and gas production facilities involved the mobilization of engineering talent, manufacturing capabilities, and construction skills in the US, Europe, the Middle East, and Asia (Fig. 1). In the process, the KG-D6 field has set numerous world records and milestones for India’s emerging oil and gas industry. First Success of Licensing Round The KG-D6 block was awarded in 2000 to a partnership of Reliance Industries (90%) and Niko Resources of Calgary (10%) in the first licensing round initiated by the government of India through its New Economic Licensing Program (NELP). Before NELP, India carried out E&amp;P activities through public-sector companies such as the Oil and Natural Gas Corporation (ONGC). ONGC remains the leading operator in India, but eight rounds of NELP have opened the country’s oil and gas sector to a variety of other public-sector companies (Indian Oil, Hindustan Petroleum, Gujarat State Petroleum Corporation), international oil companies (Cairn Energy, British Gas, Eni), and Indian private companies in addition to Reliance (Essar, Jubilant). Reliance Industries is an Indian conglomerate with extensive operations in the textile, petrochemical, and retail sectors with annual revenues of USD 28 billion. The company was launched in 1962 as yarn trading company by Dhirubhai Ambani. The growth of the company is a study in vertical integration. From yarn, Reliance built textile mills, petrochemical complexes, and entered the upstream oil and gas industry in 1999. Deepwater Discoveries The Krishna-Godavari (KG) Basin covers an area of more than 20 000 km2 on land and extends into the bay more than 24 000 km2 down a steep slope to 2000-m depth (Fig. 2). The Krishna and western part of the Godavari troughs are filled with mainly Paleozoic and Mesozoic sediments, while the eastern part of the Godavari trough contains a predominantly Upper Mesozoic and Tertiary section. The discovery of biogenic gas has been made primarily in the Upper Pliocene plays.

Control of Sulfate-Reducing Bacteria in Oil and Gas Pipelines

This article, written by Senior Technology Editor Dennis Denney, contains highlights of paper SPE 118410, "Control of Sulfate-Reducing Bacteria in Oil and Gas Pipelines," by M.D. Lohithesh and A.K. Agnihotri, ONGC, and Banwari Lal, SPE, TERI, prepared for the 2008 Abu Dhabi International Petroleum Exhibition and Conference, Abu Dhabi, UAE, 3-6 November. The paper has not been peer reviewed. A major economic loss faced by oil and gas companies is pipeline corrosion. Internal pipeline corrosion is, basically, caused by sulfate-reducing bacteria (SRB). The growth of SRB and their secondary metabolites in pipelines causes surface modifications, which can induce a more-complex corrosion process. A strategy was studied for controlling the SRB population of oil and gas pipelines. Introduction Microbial-induced corrosion (MIC) has been implicated widely in the deterioration of metal pipelines and offshore structures in the oil industry. Though several studies have reported the use of chemicals as biocides for controlling MIC, these conventional methods generally are inadequate against bacterial biofilms. Metabolically active bacteria exhibit an increased tendency to attach to metal surfaces and, depending on the availability of nutrients, to produce exopolymers to form mature biofilms. The exopolysaccharide matrix that helps form the biofilm may be involved in reducing the reactivity of chemical biocides. Attempts to circumvent this problem have focused on use of very high concentrations of chemical biocides, which may in turn pose environmental hazards. Further, after a long period of contact, corrosion-causing bacterial microflora might adapt to a given biocide and develop resistance. It is established that even if biocides are effective against planktonic population (i.e., dispersed in the water phase), their effectiveness against sessile forms (i.e., embedded within biofilm) is reduced by approximately 90%. Therefore, development continues for effective biocides, appropriate procedure for their application, and innovative measures for microbial control. This study explored the effect of biocides on the inhibition of SRB in oil pipelines. The objectives were to screen efficient and effective biocides for inhibition of MIC in oil pipelines, examine the potential of effective biocides by measuring the total sulfide production, and demonstrate the ability of biocides against biofilm (sessile population). Materials and Methods Oil and water samples were collected from the pipeline network of Oil and Natural Gas Corporation (ONGC), India, at the Bombay high offshore, Gandhar, and Ahmedabad areas. Production fluid was collected directly from the production wellheads. The SRB consortium was developed from formation water collected from corroded oil pipelines The SRB medium was prepared by adding 25 g of NaHCO3, 0.2 g of CaCl2•2H2O, 0.1 g of KCl, 1.5 g of NH4Cl, 0.6 g of NaH2PO4•H2O, 10.0 mL of vita-min, and 10 mL of trace element with a molarity of 50 mM (millimolar =mol/m3) ferric citrate in 1 L of double-distilled water. The pH of the medium was adjusted to 7.5±0.1 by use of 1 M NaOH. The SRB consortium was purified by the roll-tube method, and individual strains were identified by use of 16S rDNA analysis.

This papers tries to examine various land acquisition issues faced by the Mangalore SEZ limited, it’s projected impacts on Society, Economy and Environment and it also tries to find out its significance to Mangalore.

Techbits: Deepwater Developments Focus of Mumbai Workshop

Techbits Deepwater discoveries and development plans are expanding from well-established regions like the US Gulf of Mexico (GOM) to frontier regions such as offshore India, but there is a lag in experience that must be filled. An SPE Applied Technology Workshop (ATW) in Mumbai titled "Deepwater Development" aimed to do that, by bringing together a multidisciplinary, multinational group of 117 oilfield professionals to exchange ideas in the area of deepwater project planning and execution. Workshop Steering Committee Chairperson N.K. Mitra of Oil and Natural Gas Corporation (ONGC) welcomed all delegates and presented an overview titled "Deepwater: An Indian E&amp;P Perspective." He highlighted India's deepwater potential, which includes 1.35 million sq km of sedimentary area containing 10 billion bbl of reserves. He described ONGC's successful deepwater drilling effort at Sagar Samridhi in August 2003 that resulted in the discovery of the G-1, GS-15, and Vashishtha fields, which are scheduled to begin production in 2010–2012. Challenges preventing further deepwater developments in the region include drilling and completion technical hurdles, flow assurance, and a resistance to changing mind sets. In the keynote address that followed, A.K. Balyan with ONGC saw an urgent need to increase deepwater exploration and development off the coast of India to stem its dramatically increased petroleum import bill. This will require increased cooperation among all players in the areas of reservoir management and drilling, as well as further technology optimization. ONGC's R.S. Sharma, the chief guest of the ATW's inaugural session, pointed to nonavailability of deep- and ultradeepwater drilling rigs as driving rig costs to stratospheric levels, and estimated that each second of lapsed drilling activity at a site costs USD 146. He felt that the speed of technology development has not been keeping pace with industry needs, and placed emphasis on the areas of deepwater equipment standardization, technology for high-pressure/high-temperature (HP/HT) wells, and smart completions. Case Histories The first technical session reviewed two deepwater case histories. The first out-lined the planning and execution of the Shell NaKika project in the US GOM. Integration of several new deepwater technologies from various disciplines and an integrated team of experienced people, from subsurface planning to operations, were the keys to the success of the NaKika project. The second case study reviewed StatoilHydro's overall deepwater development and management philosophy which gives high priority to efficient inspection, maintenance, and repair. The Kristin field, with a three-stage overpressure protection design, is an example of StatoilHydro's experience with HP/HT wells.

Preparation and Characterization of Petroleum Sulfonate Directly from Crude

Sulfonate surfactants used in enhanced oil recovery (EOR) need not be very pure, such as linear alkyl benzene sulfonate, but should be similar in terms of surface activity. The possibility of preparation, isolation, and purification of petroleum sulfonate directly from crude is studied in the lab. Crudes chosen in this study are GSPC and Panna supplied by Oil and Natural Gas Corporation (ONGC), India. Crude is digested with sulfuric acid (98%) or oleum (20%) for sulfonation and then neutralized with sodium hydroxide. Finally, sulfonate surfactant is isolated and purified by a series of solvent extraction procedures using alcohols and alkanes. The sulfonate surfactant obtained is characterized with respect to EOR applicability, e.g., surface tension measurement and interfacial tension measurement against benzene. The dosing of the sulfonating agent was verified to study its effect on yield of sulfonate and surface tension value. The yield of sulfonate increases with the increase in dosing of the sulfonating agent; however, the surface activity of sulfonate decreases. Optimum yield and surface activity are obtained for sulfonate surfactants produced from GSPC crude when a crude-to-sulfonating agent volume ratio of 1:5 is used. Surface activity of sulfonate surfactant obtained from GSPC crude compares well with commercially available surfactant, TRS 10-80, used in EOR. This study also brings the possibility of an in situ generation of sulfonates in oil fields for EOR.

Ninety species, 19 named and 71 in open nomenclature, belonging to 45 known genera and one unknown, are indexed; their first and last appearance (or first and last observation) levels, compared with the stage boundaries, are used as biostratigraphical guide markers. The ostracode assemblages enable us to recognize and define the Cenomanian, Turonian and Coniacian stages. Cenomanian-Turonian faunistic communications appear between the Jaisalmer Basin and different countries of the southern Tethyan margins and the eastern and western Atlantic borderlands.
