Desain dan Pengujian Pengaplikasian Omron CP1L sebagai Remote Emergency Shutdown pada Aset Cementing

PT. X, an oil and gas service company in Indonesia, has a client facing safety risks at one of PT Y’s cementing assets. The client requested the implementation of an emergency shutdown component to mitigate the risk of accidents at the site. The primary challenge was the potential operational safety failures during cementing operations, which could lead to serious incidents without additional safety measures. This study aims to design and implement an emergency shutdown system based on the Omron CP1L to enhance operational safety at the cementing asset. The RES system was developed through a process of requirement identification, design, integration, and testing, supported by relevant literature studies. The system’s design includes the selection of appropriate hardware and software, as well as the development of logic to execute the shutdown when PT Y’s crew presses the emergency push button. Testing results indicate that the RES functions with an average delay time ranging from 1.5 to 1.9 seconds. The conclusion from this study is that the RES system is effective in enhancing operational safety and minimizing risks at PT Y’s cementing asset.

Project Selection of Indonesian Local Oil and Gas Service Company Using Analytical Hierarchy Process (AHP)

PT Duta Wisesa Servisindo or PT. DWS is a local Indonesian company that offers services in the oil and gas sector. This company was founded in 2015 when world oil prices were falling and used this momentum to invest in assets, especially in cementing units used for drilling and workover work. At the beginning of the establishment of PT. DWS believes that they can become the main local Indonesian oil and gas services company in Indonesia, because many local competitors stopped their businesses during the 2015 crisis. In 2023, world oil prices have improved, at the end of 2023 PT. DWS received 4 job offers from SOE and private sector to work on in early 2024, namely the Jambi Project, Lampung Project, Jambi Project and Cepu Project, but due to unit limitations, this company could only choose 3 job offers to work on. Because PT. DWS does not yet have a decision-making process. In this research, the Analytical Hierarchy Process or AHP is used to provide recommendations for 3 projects that are recommended to be taken by the company. In this AHP assessment, the criteria used as assessment parameters are marketing and sales, customers, financial feasibility, administration and project specifications, each of these criteria has several sub-criteria with a total of 13 sub-criteria. Based on the assessment, the criterion with the highest weight is financial feasibility (51.4%) and the sub-criterion with the highest weight is ability to pay (22.9%). After the assessment was carried out, based on the ranking, the 3 projects that were recommended to be taken were the Jambi project (33.4%), Cepu Project (30.7%) and Lampung Project (19%). Based on the assessment results, it can be seen that service users from the BUMN sector dominate compared to the private sector because they have the ability to pay and have high profitability compared to private companies, even though private companies are superior in terms of payment, administration and equipment requirements.

Updating the processes of long-term monitoring of production wells

The development of West Siberian oil and gas fields in conditions of total horizontal completion of wells showed that technologically our industry was not sufficiently ready for this challenge. To quickly build high-tech horizontal wells, to carry out multistage hydraulic fracturing in them and at the same time effectively manage the operation of high-tech horizontal wells, to ensure the required degree of reserves development, unfortunately, is not the same thing...Despite the fact that the actual coverage of well-testing, production logging and alternative long-term distributed monitoring based on stationary information and measurement systems in Russia in recent years has been extremely insignificant, a cumulative analysis of the data obtained in the industry on the leading vertically integrated oil companies speaks about the following negative trends identified by diagnostic methods: the existing domestic technologies do not allow to regulate and manage the inflow and intake profiles in horizontal wells, horizontal wells with multistage hydraulic fracturing, multibarrel wells, thereby initially ensuring uniform production of recoverable oil and gas reserves in the drainage zones of wells with horizontal completion; the undesirable breakthroughs into the borehole of a horizontal well of water and gas detected by means of borehole diagnostics were eventually not isolated by field services, as a result of which the wells were decommissioned prematurely, without ensuring the achievement of the project accumulated indicators of hydrocarbon production; according to measurements in the horizontal wells, incomplete confirmability of multistage hydraulic fracturing designs was found (both in estimates of crack lengths and in terms of determining the places and forms of their initiation in holes); finally, the profiles of the inflow and the composition of the inflow studied in dynamics, as a rule, changed quite quickly in time from the moment the wells were launched for the selection of products, which usually led to unpredictable production losses (flow deterioration was usually recorded from the toe and the central parts of the boreholes of horizontal wells); the most typical reason for the decrease in productivity in horizontal wells and horizontal wells with multistage hydraulic fracturing should be recognized as the clogging of boreholes with sand and proppant, as well as the lack of the ability of producers to promptly clean the boreholes without creating repression on the formation; all these problems are certainly aggravated for objects of the category of hard-to-recover initial-recoverable reserves of hydrocarbon raw materials. The fixation and justification of the above conclusions were largely obtained due to the gradual transition of oil and gas producing and service companies from traditional one-time complex measurements by production logging and well testing to permanent long-term stationary monitoring of well testing and production logging parameters in production wells using various types of point-distributed and distributed modular means of stationary information and measurement systems. This progressive high-tech direction of borehole research can potentially be significantly developed and spread in the industry in the near future (which will objectively contribute to the achievement of higher oil and gas recovery coefficients), provided that the state bodies supervising the development of hydrocarbon raw materials (Rosnedra, Ministry of Energy of the Russian Federation) will involve measures to motivate a deeper and more detailed study of the state of development of residual recoverable reserves at the developed fields.

A Feasibility Study on the Conversion from Manual to Semi-Automatic Material Handling in an Oil and Gas Service Company

In manufacturing companies, manual material handling (MMH) involves lifting, pushing, pulling, carrying, moving, and lowering objects, which can lead to musculoskeletal disorders (MSDs) among workers, resulting in high labor costs due to excessive overtime incurred for manual product preparation. The aim of this study was to show how ergonomic measures were used to reduce the risk of MSDs and to reduce operating costs in the warehouse department of an oil and gas service company. A preliminary study using the Nordic Body Map survey showed that the workers experienced pain in various parts of the body, indicating the presence of MSDs. The researchers then used methods such as the Rapid Upper Limb Assessment (RULA), Rapid Entire Body Assessment (REBA), and National Institute for Occupational Safety and Health (NIOSH) assessments to verify whether the MMH activities had an acceptable level of risk. The results revealed that certain manual material handling (MMH) activities were assessed as low–very high risk, with RULA scores ranging from 3 to 7 and REBA scores ranging from 4 to 11. An immediate solution was to replace the manual process with a semi-automatic process using a vacuum lifter. A feasibility study was conducted using the net present value (NPV), internal rate of return (IRR), and payback period to justify the economic viability of the solution. The analysis indicated that implementing the vacuum lifter not only mitigated the risk of MSDs but also reduced the operating costs, demonstrating its viability and profitability. Overall, this study suggests that implementing a vacuum lifter as an assistive device in the warehouse would be a beneficial investment for both the workers and the company, improving both well-being and finances.

The Effect of Corporate Greenwashing on Employees’ Environmental Performance: Person–Organization Values Fit Perspective

In the present study, we construct a model of greenwashing on employees’ environmental performance based on person–organization fit theory. Path analysis and hierarchical regression methods were used to examine randomly selected data collected from 269 employees in eight Chinese gas service and chemical production companies. The results of the analysis reveal that employees’ perceived person–organization values fit mediates the relationship between organizational greenwashing and employees’ environmental performance; employees’ environmental beliefs not only positively moderate the relationship between corporate greenwashing behavior and employees’ perceived person–organization values fit, but also positively moderate the indirect effect of employees’ perceived person–organization values fit between organizational greenwashing and employees’ environmental performance. We provide some theoretical contributions to organizational greenwashing, and practical implications are also offered.

Analysis on Demand for Service Quality of Pertamina Klaten Indonesia and PTT Yarang District Pattani Thailand Gas Stattions

This study aims to examine the gaps in consumer service expectations and perceptions in two state-owned oil and gas service companies in two cities, namely Klaten Indonesia and Pattani Thailand. Testing the model used Servqual Test. The research design was quantitative. The hypothesis formulation used the Cronin Taylor Importance Servqual Test formula. The population is all consumers, the sample of consumers are adult consumers in both cities who have finished getting the services of the two Public Fuel Filling Stations. The technique of taking sample was purposive as many as 200 consumers. The test results show that the dimensions of empathy at the Pertamina Klaten gas station have the largest gap value. Pertamina gas stations parties must improve services which still provide the largest gap value to improve the quality of services and people satisfaction. Recommendation for this research, two gas stations must improve of the quality of services. The competitive advantage of institutions will be created in the future

The optimization of human and material resources to increase competitivity of oil and gas service companies

This work has as basis subjects related to resource planning tools such as Sales and Operations Planning (S&OP) and Enterprise Resources Planning (ERP) software and Lean. In this context, the guiding question is: How could human and materias resources be best optimized to deliver an operation with less safet risks, less emissions, less suceptability to market fluctuation condistions, profitability and competivitivty for both operators and service oil and gas companies? The objective of this study was to review existing methods to optimize the use of human and material resources on oil and gas service companies to prevent unavailability of assets or its failures over time. For this, it was adopted as methodology the bibliographic review and an example of a service company create through another article as a study case. As conclusion there is a proposition of best practices and a methodic process that can be directly used on the resource planning of other industries.

Critical Evaluation of the Current Bonus and Merits Policy and Its Impacts on Employees’ Pay Satisfaction: Reference to Two Oil and Gas Service Companies

This research explores the relationship between the current Bonus & Merit (B&M) policy along with its effects, if any, and pay satisfaction (PS) of the employees working in two oil and gas service companies. It should be noted that once satisfied in terms of pay, working staff are expected to deliver much more intensely at all levels so that the company realizes its objectives. With this notion in mind, the study aims to explore in-depth ways and means to get to the desired level of pay satisfaction that suits the working staff. The research seeks to conceptualize various associated dimensions generated from an extensive literature review aiming to prove or otherwise the sets of hypotheses and research questions. A sequential explanatory mixed methods research pattern is employed. The study findings indicate the importance of analysing all associated dimensions that are generated from and within the content of the B&M policy. This impacts the employees’ level of PS, and accordingly their expected productivity. In other words, the terms and contents of the B&M policy need to be viewed differently, in accordance with the study findings so that the objectives are realized.

Impact of basic psychological needs on organizational justice and helping behavior: a self-determination perspective

PurposeIntegrating the social exchange perspective of helping behavior with self-determination theory (SDT), this study seeks to examine the impact of employees' psychological needs on perceived organizational justice and the impact of perceived organizational justice on employees' helping behavior.Design/methodology/approachCross-sectional and cross-organizational data were obtained from 177 full-time employees employed in 12 small- and medium-sized oil and gas service companies. A partial least squares approach using SmartPLS was employed to test the hypotheses.FindingsResults illustrate that the psychological need for competence and need for autonomy are positively related to perceived distributive and procedural justice, respectively. Moreover, perceived distributive and procedural justice are related to helping behavior. Furthermore, perceived distributive justice fully mediates the relationship between the psychological need for competence and helping behavior, whereas perceived procedural justice partially mediates the relationship between the psychological need for autonomy and helping behavior.Originality/valueFrom a theoretical standpoint, this study offers some theoretical explanations for how the basic psychological needs identified by SDT activate employees' perceived organizational justice. Practically, this study offers several managerial recommendations that help managers manage helping behavior in the organization effectively.

Look Ahead of the Bit While Drilling: Potential Impacts and Challenges of Acoustic Seismic While Drilling in the McMurray Formation

SummaryThe oil and gas industry, operating and service companies, and academia are actively searching for ways to look ahead of the drill bit while drilling to reduce the risks and costs of the operation and improve the well-placement process. Optimal drilling in challenging and highly heterogeneous reservoirs, where geological data cannot adequately constrain high-frequency variations in rock properties, requires reliable subsurface information from around and ahead of the drill bit. To provide this, we have developed a seismic-while-drilling (SWD) imaging algorithm using signal processing, drillstring modeling, and prestack wave-equation migration.To extend the visibility ahead of the bit, we use the drill bit as a seismic source and image the changes in acoustic properties of rocks both around and ahead of the drill bit. The common practice is to build reverse vertical seismic profile (R-VSP) gathers. Here, we use a blind deconvolution algorithm to estimate the drill-bit source signature from the data directly. Alternatively, we can estimate such a signature through drillstring modeling and surface measurements (i.e., hookload and hook speed). The drillstring dynamics are modeled and analyzed using Riemann's invariants and a backstepping approach in a field-verified model. Next, we enter the estimated source signature into the prestack wave-equation depth-imaging workflow. Our simulations show that providing the drill-bit source signature to the prestack wave-equation depth migration consistently delivers reliable subsurface images around and ahead of the drill bit.The output of our workflow is a high-resolution subsurface image, which is then applied to provide vital information in oil-sands reservoirs for placement of steam-assisted-gravity-drainage (SAGD) well pairs. Compared with conventional practices, the proposed methodology images around and ahead of the drill bit enable interactive decision making and optimal well placement. The key feature of the presented methodology is that instead of cross correlating the SWD data with the pilot trace and building R-VSP gathers, we use the estimated drill-bit source signature and deliver high-resolution prestack depth-migrated images.Through numerical modeling, we tested the potential impacts, validity, and challenges of the proposed methodology in drilling horizontal wells in SAGD settings with an emphasis on the McMurray Formation. We further compared the results with the conventional drilling practice. In contrast to existing tools that have limited depth of penetration, interpreting SWD data in real time confidently maps key target features ahead of the drill bit. This imaging workflow provides sufficient time to precisely control the borehole trajectory and stay within the desired reservoir zone. Accordingly, it mitigates the risk of intersecting mudstone-filled channels and lean zones.

Knowledge Acquisition and Resource Exploitation of Indigenous Oil and Gas Companies in Niger Delta, Nigeria

This study examined the relationship between knowledge acquisition and resource exploitation of indigenous oil and gas service companies in Niger Delta, Nigeria. Primary data was generated through structured questionnaire. The methodology used was quantitative and a cross-sectional survey method was adopted in the investigation of the study variables. The population of this study consisted of 332 (Three Hundred and Thirty Two) staff members of 26 highly functional/ active operational indigenous oil and gas service companies operating in the Niger Delta region of Nigeria. A sample size of 181 was determined using Taro Yamen sample size determination formula. The reliability of the instrument was achieved by the use of the Cronbach Alpha coefficient with all the items scoring above 0.70. The hypotheses were tested using the Spearman’s Rank Order Correlation Coefficient with the aid of the Statistical Package for the Social Sciences version 22.0. The findings of the study revealed that there is a significant relationship between knowledge acquisition and resource exploitation of indigenous oil and gas service companies in Niger Delta, Nigeria. The study recommends that indigenous oil and gas companies should foster relationships with critical stakeholders such as customers and suppliers and develop networks that may bring valuable information to the company, and opportunities to get new ideas from external parties should never be neglected. The managerial implications follow that if a firm enjoys a broad and connected client network it can facilitate the emergence of ambidexterity by stimulating higher levels of trust internally. However, if this firm is heavily dependent on teams to develop ambidextrous abilities in a self-managing and contextual fashion, trust may prove to be detrimental.

Data integration for offshore decommissioning waste management

Abstract Offshore decommissioning represents significant business opportunities for oil and gas service companies. However, for owners of offshore assets and regulators, it is a liability because of the associated costs. One way of mitigating decommissioning costs is through the sales and reuse of decommissioned items. To achieve this effectively, reliability assessment of decommissioned items is required. Such an assessment relies on data collected on the various items over the lifecycle of an engineering asset. Considering that offshore platforms have a design life of about 25 years and data management techniques and tools are constantly evolving, data captured about items to be decommissioned will be in varying forms. In addition, considering the many stakeholders involved with a facility over its lifecycle, information representation of the items will have variations. These challenges make data integration difficult. As a result, this research developed a data integration framework that makes use of Semantic Web technologies and ISO 15926 - a standard for process plant data integration - for rapid assessment of decommissioned items. The proposed solution helps in determining the reuse potential of decommissioned items, which can save on cost and benefit the environment.

X-ray densitometry of drilling fluids at the rig standpipe

Fluids used during well construction operations serve as a primary barrier for well control, with the fluid density generating sufficient hydrostatic pressure in the fluid column to control downhole formation fluids and gas. Real-time density measurement at the well inlet, where high pressures of many thousands of psi can occur, is highly desirable in order to maintain well control. This improved characterization of the well bore pressure profile allows one to drill wells with narrow drilling margins without non-productive time from well control events, resulting in safer and more cost-effective well construction operations. Gamma ray densitometers are suitable measuring devices for high-pressure density measurement. Typical flow conditions encountered at the inlet, such as a fully filled pipe and a homogeneously mixed mud, are very conducive to their use. In-spite of their high measurement accuracy and relatively fast response times, however, these meters have seen limited adoption in field. This is primarily because the meters come with safety concerns due to the radioactive source required for gamma ray generation. Additionally, the source has to be tracked throughout its life and properly handled during storage, transportation, installation and disposal. Given these concerns and challenges, a majority of oil and gas operating and service companies use manual density measurements at the mud pits using a pressurized mud balance. To help change this rather antiquated and infrequent practice that relies on manual labor, this paper evaluates the feasibility of using a non-radioactive, X-ray based densitometer as an alternative to the gamma ray meter. X-ray densitometry works on the same proven principles as gamma ray densitometry, without the latter's drawbacks. Two X-ray methods, an empirical method and a model-based method (inspired by a technique used in the medical field known as single X-ray absorptiometry) are presented here. Real-time density measurements on the high pressure line with an accuracy of 99% or better and a measurement frequency of 1 Hz are feasible using these methods.

ANALYSIS OF VALUE STREAM MAPPING AND LEAN SYSTEM APPLICATION TO IMPROVE TENDER CREATING PROCESS: A CASE STUDY IN PT XYZ INDONESIA

PT XYZ Indonesia, established in 1986, is a US-based oil and gas service company who providesservices from drilling and evaluation, to completion and production. As a service company with huge amount field projects, its Business Development division is a spearhead for the company’s growth. Over the years, the competition is getting tougher with many local companies, besides other new international service companies, are penetrating the Indonesia’s market. PT XYZ Indonesia have been utilizing the same procedure and process map to develop its business strategy, win tenders, execute field projects, and ultimately expand its operation. The purpose of this research is to analyze the current process of tender creation; identify the challenges the company has been having to win more projects, and eventually provide an improvement to the current-state map. The qualitative research was done by having field observations, conducting interviews, and analyzing secondary data, to reveal the issues at hand. The results show that PT XYZ Indonesia, especially its Business Development division, is not utilizing its resources to full capacity by not managing it efficiently – especially in forms of administration and workforce. In conclusion, a set of recommendations to improve the tender creating process specifically, and its Business Development strategy generally, were formulated.

Fewer Grads + More Jobs: A Winning Formula for Job Hunters

The 2019 graduating class of petroleum engineers will mark the last gasp of a boom before a steep drop in the size of future graduating classes coming out of US universities. After a class of nearly 2,000 petroleum engineering graduates next spring, the graduation rate over the next 3 years will fall to less than 1,000 per year, according to an annual survey of US petroleum engineering programs by Lloyd Heinze, a professor at Texas Tech University. The survey includes primarily US universities. The numbers are a direct reflection of the sharp downturn in oil prices that began in 2014 and caused large downsizing among oil and gas operators and service companies. For young engineers looking for jobs after college, it represents a welcome change from the rocky job market faced by graduates after the industry switched into job-cutting mode. For employers used to having their pick of the top students since the bust began in 2015, it could mean being one of several bidders for a shrinking pool of graduates. Professors on campuses are seeing signs of improvement, but they caution that the evidence is more anecdotal than numerical. “A good number of seniors have jobs and a lot do not. One thing is that it is a big senior class,” said Karsten Thompson, department chair for the petroleum engineering program at Louisiana State University (LSU). It is too early for hard numbers but “there are more companies on campus with more students having internships and job offers.” “Internships went quite well this year. It looks like the recovery is under way. Students are much more comfortable,” said Erdal Ozkan, a professor at Colorado School of Mines. The job market is much improved, said John Lee, a professor at Texas A&M who also sees improved internship opportunities. Graduating Boomers The class of 2019 is made up of the last big crop of freshman enrolled back in the fall of 2014 when the bust killed the assumption that $100/bbl oil was a given. The nearly 2,000 seniors in the 2018–2019 class is considerably smaller than the past two, which exceeded 3,200, but it is double the size of three classes that follow. Texas Tech has 77 seniors now, compared with a peak total of 227 in 2014, and only 43 juniors following them. The junior class is 80% lower than the 2015 peak. That drop is an indication of Texas Tech’s decision not to limit petroleum engineering enrollment during the boom—only a few schools including Texas A&M and the University of Texas capped enrollment—and the quick reactions of a “population of students and parents who were faster to realize the downturn” because so many live in West Texas where the industry is all around them. Between the boom in the early 1980s—where schools provided a generation’s worth of exploration and production professionals—and the recent boom that produced many more grads, was a long, deep slump.

How Do Oil and Gas Investors Pick Entrepreneurs? Vice Versa?

Private equity and venture capital firms are just as important to the evolution of the oil and gas industry as the leading operators and service companies. This became evident during the oil price crash when public equity opportunities disappeared and lenders shied away from the industry amid scores of bankruptcies. Illustrating the point earlier this year was Wil VanLoh, founder and CEO of Quantum Energy Partners, who boasted during the NAPE Global Business Conference that his firm would “look really similar to a superindependent” if it were to aggregate all the companies in which it’s currently investing, which altogether tally 2.3 million net acres, 350,000 BOE/D, and 32 rigs working across the US and Canada. With the backing of private investment, entrepreneurs who previously worked for companies such as Shell, Anadarko, Halliburton, Baker Hughes, and even smaller, lesser known entities have applied their unique skills and ideas to find, develop, and produce the latest generation of prolific oil and gas fields quicker and with less money than ever before. But finding those innovators who are actually capable of turning their dreams into reality is difficult. And when you’re the firm tasked with bearing the financial risk that comes with backing fledgling companies that hope to break into an already volatile industry, you tend be choosy. Enter Charlie Leykum, founder of CSL Capital Management, a 10-year-old private equity firm that builds and acquires controlling interests in oil and gas service and equipment companies. It’s currently launching its $1.5-billion Fund III as well as a special-purpose acquisition company, which raises capital from public investors, enabling them to participate in private equity purchases. “So much of what we do is finding not just an individual or a group of individuals who are technically or commercially really savvy,” but finding a “harmonized, well-working team,” Leykum said during the SPE Gulf Coast Section’s recent Innovation Entrepreneurship Symposium. CSL only considers business plans where a team is either in place or assembling with “a subject matter expert who’s the key decision maker” as well as technical and operations personnel. Together, they must have a firm grasp of the challenges and risks involved in building a business. When looking at possible investments, CSL wants technical leadership in a market. When CSL invested in a fracturing company in the early 2000s that ended up successful, Leykum said, the firm partnered with a major service company’s “lead fracturing executive for the business line” whose skills and expertise could solve—and had solved—unique challenges in different basins.

Further, this study provides discussion, implications and conclusion.Keywords: Career Development Tools, Proactive Behavior, Malaysia, SPSS

Ultrasonic velocity measurements on thin rock samples: Experiment and numerical modeling

The ultrasonic pulse transmission (UPT) method has been the gold standard for laboratory measurements of rock elastic properties for decades, and it is used by oil and gas industry and service companies routinely. In spite of the wide acceptance and use of the UPT method, experimentalists are still looking for ways to further extend the limits of its applicability and to improve its state-of-the-art practices. One of the problems that limits wider application of the method is the length of the standard samples used (approximately 40–100 mm). This is a crucial limitation either in the case of a damaged core when preparation of a standard size sample is impossible or in the case when an ultrasonic experiment is combined with saturation or desiccation processes that might be extremely time-consuming on the long samples. On the other hand, thinner samples are not typically used due to the implication of inhomogeneity of stress fields inside and whereas few results of the measurements on thin disc samples have been reported in the literature, detailed justifications of the procedures have not been done yet. To fill this gap, we compare ultrasonic velocities measured at confining stresses up to 50 MPa done on standard and thin samples with lengths of 60 and 15 mm, respectively. First, we evaluate a new developed experimental setup for ultrasonic measurements on thin discs and develop a detailed experimental procedure. Then, we use finite-element modeling to numerically simulate stress fields in both types of samples. Finally, we compare the ultrasonic velocities measured on the thin discs and on standard samples and determine how to obtain reliable elastic properties on thin samples.
