New Generation of Pulsed-Neutron Multidetector Comparison in a Challenging Multistack Clastic Reservoir: A Case Study in Brown Field, Malaysia

Running pulsed-neutron logs in Malaysia has previously been plagued by results with high uncertainties, especially in brown fields with complex multistacked clastic reservoirs. Together with a wide range of porosities and permeabilities, the acquired logs quite often tended to yield inconclusive results. In addition, the relatively fresh aquifer water (where salinity varies from 5,000 to 40,000 ppm) makes reservoir fluid typing and distinguishing between oil and water even more challenging. As a result, the inconsistencies and uncertainties of the results tend to leave more questions than answers. Confidence in using pulsed-neutron logging, especially to validate fluid contacts for updating static and dynamic reservoir models, deteriorated within the various study teams. Due to this fact, the petrophysics team took the initiative to conduct a three-tool log off in one of their wells with the objective of making a detailed comparison of three pulsed-neutron tools in Malaysia’s market today. The main criteria selected for comparisons were the consistency of the data, repeatability, and statistical variations. With recent advancements in pulsed-neutron (multidetector) tool technology, newer tools are being equipped with more efficient scintillation crystals, improving the repeatability of the measurements as well as the number of gamma ray (GR) count rates associated with the neutron interactions. In addition, the newer tools now have up to five detectors per tool, with the farthest detector supposedly being able to “see” deeper into the formation, albeit at a lower resolution. With these new features in mind, the log off was conducted in a single well with a relatively simple completion string (single tubing, single casing), logged during shut-in conditions only, and the logs were acquired directly one after the other (back to back) to avoid bias to any particular tool. Both sigma and spectroscopy measurements were acquired to compare the capabilities of each tool. Due to the relatively freshwater salinity, the carbon-oxygen (C/O) ratio from the spectroscopy measurements is used to identify the remaining oil located in the reservoirs, while the sigma measurements determine the gas-oil or gas-water contact, if present. This paper will illustrate the steps taken by Petronas Carigali Sdn Bhd (PCSB) to compare the raw data and interpreted results from the three pulsed-neutron tools. Consequently, a comparison from all the tools was made to the current understanding of the reservoir assessed. The points from these comparisons will then show which tools are favored over the rest.

High-Level Performance Analysis Model for Mature Offshore Assets

In general, most offshore platforms are designed for 20 to 30 years of lifespan. After the field completed its maximum production plateau for a certain period, the reservoir pressure started to deplete, resulting in a decline in production rate until it is uneconomical to produce from the field. This declined production phase is referred to as Mature Offshore Fields/Assets. Almost 90% of offshore platforms in Peninsular Malaysia Assets operated by Petronas Carigali Sdn Bhd (PCSB) are within this phase. The study objective is to establish an analysis tool by consolidating the data from various system resources into a single presentation to provide the status of mature field performance, visualize the area that requires improvement, and subsequently identify performance improvement recommendations. The study will also focus on identifying which data and the resources needed to be extracted and the standards mentioned in guidelines available in the company to be used as a benchmark or comparison. This data compilation is interpreted into a Microsoft Excel spreadsheet and charts. As the study focuses on mature field operations, the three elements been identified as study subjects, i.e. plant utilization as production declining, operating cost and unplanned trips or shutdown. From the data simulation sample, the performance of Field A can be summarized and visualized clearly, and the area of improvement required can be identified with value creation being estimated.

Stardust Petroleum Sendirian Berhad: how to inculcate the pro-active safety culture?

Learning outcomes The learning objectives of using this case are as follows: to understand the concepts of organizational structure, organizational culture and organizational change; to expose students to the problems that may encounter organization when it intends to bring changes in culture; to stimulate students’ understanding of the necessity to build positive organizational culture; to advance students’ knowledge about oil and gas industry; to develop students’ understanding of using Levin’s model of cultural change; and to illustrate the challenges that an organization might face while changing its existing culture. Case overview/synopsis This case teaches about the importance of boosting positive organization culture to accept organizational change. Stardust was established in 2013 as Petronas Carigali Sdn Bhd’s subsidiary. The company was established to manage small and marginal field in Malaysia which was under the oil and gas field that had smaller reservoir and lasted for four to five years. On 2014, Stardust was given an opportunity to take over one of the fields to manage. However, during the process of handing over the facility and field from the parent to the new company, the tanker caught fire in one of its pump in the pump room. The fire resulted substantial damage to the pump room; two out of four pumps were totally damaged. It delayed the oil production for more than a month. Total estimated damage due to the fire incurred RM19m losses. Direct cost included replacing two new 400 kW pumps, repairing the damaged pump room with new manifolds and painting, and cost of shutdown production for 40 days. Investigation was initiated to identify the causes of the fire which revealed that human error, mostly peoples’ negligence was one of the major reasons along with location, equipment and procedure. The Health, Safety and Environment department of the company was given the task to create ‘Living Safety’ culture among the crew. Being the head of this department, Tarmizi found it very challenging to inculcate the culture ‘Action Today, Perfect Day Tomorrow’ and was thinking how to instill this culture with zero failure by the end of the calendar year which is December 2016. The time was running fast as the parent company emphasized to handle the situation urgently and to ensure that the similar incident will not happen in the future. If it re-occurs, it will jeopardize the trustworthiness of Stardust with the other parties involved and also the parent company might not allow the company to operate other facilities, which will put the company at stake to remain competitive in the oil and gas business. Complexity academic level This case is suitable to use in advanced undergraduate level, MBA and MSc to teach organizational behavior and organizational theory courses.

Effectiveness of Human Resource Utilization in Oil and Gas Project

Employees are very important to every organization. This study attempts to examine the effectiveness of current human resource management utilization and practices in oil and gas projects in Malaysia, as well as to study the importance of having effective human resource management practices utilization. The human resource management practices namely training and development, performance appraisal, compensation, employee empowerment and ownership as well as work environment are the main practices that has being focused. A questionnaire form has been distributed to the employees of PETRONAS Carigali SDN BHD (PCSB), a leading oil and gas operator in Malaysia including their contractors.

Load resistance factor design (LRFD) calibration of load factors for extreme storm loading in Malaysian waters

Petronas Carigali Sdn Bhd (PCSB) performs its operations in three regions in Malaysian waters. Currently, fixed offshore structures are designed in accordance with ISO 19902, which is meant to provide guidance for the design of fixed offshore structures internationally, but the load factors in ISO 19902 are often derived from studies performed in the Gulf of Mexico and the North Sea environments. One such load factor is the 1.35 for environmental loading that has been prescribed within ISO 19902. Site specific metocean studies in Malaysian waters reveal environmental conditions that are more benign than the Gulf of Mexico and the North Sea. This study presents the results of a component-based approach and investigates the suitability of the 1.35 load factor for environmental loading in Malaysian Waters to achieve the same target reliability for a similar structure designed consistent with the provisions of the API RP 2A-WSD. First-order reliability methods (FORM) have been undertaken using a database of tubular components with representative geometries, bending-to-axial stress ratios, dead-to-live load ratios and environmental to gravity load ratios. The analysis results show that if the target were to be based on the weighted average probabilities inherent in the API RP 2A-WSD 21st Edition, an environmental action factor of 1.245 (Region A), 1.295 (Region B) and 1.255 (Region C) with the ISO provisions will on average achieve similar reliability.
