Fuzzy Cost

The diving chamber is an important system needed for diving operations in the oil and gas industry. Divers use it for various purposes. Thus, the safety level of the diving chamber needs to be very high at all times and the system needs to be in a good state. To achieve this, various control measures such as control measures 1 and 2 can be adopted in preventing failures/hazards or mitigate their consequences. In this study, fuzzy cost algorithm is used to estimate the cost of using control measures 1 and 2 in ensuring optimal operational level for the diving chamber, while the preference degree approach is adopted in prioritizing the aforementioned cost of control measures 1 and 2. The result of the analysis indicated that control measure 2 is the most cost effective approach.

Qatar is one of the major natural gas (NG) producing countries, which has the world’s third-largest NG reserves besides the largest supplier of liquefied natural gas (LNG). Since the produced water (PW) generated in the oil and gas industry is considered as the largest waste stream, cost-effective PW management becomes fundamentally essential. The oil/gas industries in Qatar produce large amounts of PW daily, hence the key challenges facing these industries reducing the volume of PW injected in disposal wells by a level of 50% for ensuring the long-term sustainability of the reservoir. Moreover, it is important to study the characteristics of PW to determine the appropriate method to treat it and then use it for various applications such as irrigation, or dispose of it without harming the environment. This review paper targets to highlight the generation of PW in Qatar, as well as discuss the characteristics of chemical, physical, and biological treatment techniques in detail. These processes and methods discussed are not only applied by Qatari companies, but also by other companies associated or in collaboration with those in Qatar. Finally, case studies from different companies in Qatar and the challenges of treating the PW are discussed. From the different studies analyzed, various techniques as well as sequencing of different techniques were noted to be employed for the effective treatment of PW.

The Impact

The offshore hydrocarbon basins of the world and their neighbouring countries are faced with an immense decommissioning challenge. Uncertainties in regulation and costs, coupled with limited environmental data, stifle consideration and support for alternative options to full removal. In separate regions, scientists and industry are forming partnerships and commencing research that advances understanding of regional and ecosystem-scale processes, including the habitat value of oil and gas infrastructure. With similar decommissioning-related marine research priorities being identified globally, a more coordinated approach to such research is needed: a global decommissioning marine research network and taskforce. This taskforce would not only be highly cost-effective, but it would also enable consistent approaches to science and management of the marine environment and secure protection and conservation of global marine resources. This network and taskforce would bring together leading scientists and experts in the oil and gas industry to develop an international research program that will significantly advance our understanding of the consequences to ecosystems as a result of decommissioning, as well as identify the differences and commonalities in environment–infrastructure interactions across different geographical regions. The outcomes would support sustainable installation and decommissioning practices worldwide and ensure that policies adhere to international agreements on environmental protection.

Structured Approach

The start of the new millennium will see companies in the oil and gas industry faced with a dual challenge. Not only will they have to undertake exploration in more demanding terrain and environments, but they also face far more competition in what they previously regarded as their traditional marketplace. The goal of meeting both shareholder and customer needs, while simultaneously attempting to increase market share by becoming more competitive, will be paramount if this success is to be achieved. While a number of strategies have been developed over the last decade in an attempt to achieve and balance these financial goals, the control and reduction of costs play a significant part in all such ‘cost effective’ programs. Past approaches have targeted the organisational structure, internal processes and strategic advantage through acquisitions, mergers and downsizing. However, any gains realised by such programs must be continuously improved upon by implementing innovative approaches to future reductions and controlling costs. Some companies have shifted the focus from internal cost scrutiny to influencing and ultimately controlling external factors of cost. The supply chain offers a tremendous opportunity to drive out costs, one such approach being to partner with the best suppliers of key components to shorten delivery times while minimizing life cycle costs. It is therefore paramount that one distinguishes between those who are simply suppliers and that smaller group who are the best suppliers, all the while fostering a win-win relationship by sharing growth and profitability. This paper will introduce the concepts of the Supplier Performance Measurement Process (SPMP), which NOVA / TransCanada introduced in late 1997 to measure and manage its suppliers’ performance in the provision of a few strategically critical commodities. To provide context for this paper two such commodities, high pressure line pipe and high integrity pipe coatings are addressed in some detail. The application of the process to these commodities alone yielded a capital cost reduction of 6%. The paper explains in practical terms, the steps involved in the implementation of SPMP, and provides a simple process for eliciting feedback on the efficacy of the procurement process.

The introduction of Integrated Operations (IO) in the offshore oil and gas industry makes distanced and distributed decision-making a growing part of normal work. Some functions have been transferred from offshore installations to onshore offices as a consequence of the technologies that have recently become available. The authors analyze whether the onshore organization is ready for increased responsibilities by increasing the resilience in its work patterns, since resilience is important for maintaining or increasing safety level compared to current operation, where personnel on board installations can observe the plant at first hand. This study has been performed as a case study of an onshore Support Center in a drilling company at the start of the process of using the Support Center. The establishment of the Support Center involved re-arranging the office arrangements to an open landscape for all offshore installation support personnel and grouping them according to disciplines. They also acquired new technology, including video conference equipment. Important findings are that developing resilience has to be followed through at all levels of the organization. Time and resources have to be made available when work practices change, providing the physical framework alone does not improve resilience. The study also offers a more detailed description of capability resilience and which aspects should be considered when developing resilience. The authors look at the status so far in the change process and also find areas that should be developed in order to increase resilience further.

Oil And Gas Operations

The availability of reliable, cost effective power and temperature control is critical to all facets of oil and gas operations around the globe. Dropping of global oil prices has had significant effects on long-term liquefied natural gas contracts. Oil and gas producers have experienced a decline in profits, and unprecedented pressure has been put on these companies to remain viable. Many marginal operators have experienced freezing of exploration budgets, delays on future planned expansions and the wind down of non-essential operations. Herein are four case studies from the oil and gas industry, which highlight several business solutions that assisted companies to stabilise their profits by starting production early, reducing operational down time and assisting process efficiencies.

Explosion Risk

Management of the risk related to the loss of containment of flammable fluid is paramount to ensure safe operations at facilities processing or storing flammable fluids. According to best industry practice, an extensive set of safety functions—including measures that reduce the frequency of initiating events (e.g. leaks) and measures that mitigate consequences in case of ignition—are implemented in design to control the risk. Adopting the risk-based design principles that are commonly enforced in the oil and gas industry, the performance of implemented safety barriers are assessed both qualitatively and quantitatively using different methodologies such as hazard and operability analysis (HAZOP), failure mode and effects analysis (FMEA), and quantitative risk analysis (QRA). The ultimate outcome from the QRA methodology is used to assess the overall risk level as well as to assess dimensioning accidental loads (DALs) for equipment and structures that will ensure a design that is within the tolerable risk level set for the facility. An accurate assessment of DALs resulting from fires and explosion is crucial to manage both the risk and corresponding cost driving factors. The most critical safety barrier in this regard is to minimise leaks and thereafter to prevent ignition of the dispersed flammable fluid. A fundamental safety design principle is to find ways to avoid the occurrence of incidents rather than implement measures that mitigate consequences. This peer-reviewed paper demonstrates the significance of modelling the safety functions that are in place to ensure that the initial leak does not ignite by presenting a case example for different layouts of a conventional jacket installation with gas turbines. It is concluded that the difference between various available ignition models can be more prominent than the uncertainty related to any other model element in the QRA. To uncover potential hazards not reflected by the model and identify optimal control measures, the effect of the ignition model applied should be investigated in detail for installations where the QRA displays a prominent fire and explosion frequency.

The offshore oil and gas industry has seen a continual trend of conservatism in design for applications where a high level of strain is expected during the installation phase, leading to a tightening of the acceptable mechanical property performance of the linepipe. This is especially true with regards to longitudinal tensile properties in the strained and aged condition. Due to the expected change in data seen throughout previous projects, are the tightening expectations realistic for the manufacturers and cost effective for the client? The current condition that is widely accepted for the release of pipes suitable for high strain events is straining and ageing. However is this appropriate given that pipes are coated (aged), installed (strained) then left over time (aged)? These questions will be investigated through a series of tests and data analysis. For this project a conventional ageing as per the standard and a coating simulation were used, with all test pieces having either 0% or 1% applied strain. The test pieces for this project were tested in one of seven conditions; • As manufactured • Aged (at 200°C/5min or 250°C/1hr) • Strained and aged (1% strain applied then aged at 200°C/5min or 250°C/1hr) • Aged and strained (aged at 200°C/5min or 250°C/1hr then 1% strain applied) To ensure a direct comparison in the data the comparable test pieces were taken from the same circumferential position on the pipe. All testing for this project was carried out on material of a similar composition and future development of this work will comprise of documenting the effect on different microstructures, t/D ratios and levels of strain. It was clear from the project that changing the conditions used had an impact on the results. This could have implications for the industry in the future and has set up a scheme of development following on from this project to gain a greater understanding.

Oil and Gas Industry (OGI) faces a number of evolving and various types of risks and hazards that give rise to serious incidents. To conduct this study 801 incidents reports have been numerically analyzed, evaluated and interpreted. These incidents reports covered various severity levels, which have been occurred in 6 regions across the world, from 2014 to 2016. The analysis focused on global oil and gas industry. The study has shown that Occupational Work-related Incidents (OWRIs) occur mostly in October and especially in spring time. In addition, it has pointed out that the region of North America is the most affected area; almost one-third of OWRIs occurs in turbine hall area. Surprisingly, the study also revealed that three-quarters of the OWRIs did not occur in High-Risk Activity (HRA) and half of the incidents took place with no tooling involved. Noticeably, the main recurrent and frequent event was struck against or by (SAoB) that resulted dominantly in slight injuries that required only first aid care, and the most affected body part is the finger by “Cut (Laceration)/ Pinch”. The study has confirmed that the hazardous working environment in OGI was the direct cause for half of the OWRIs. However, based on the revealed results, it will be the assumptions that human factors have a crucial impact on the workplace safety and a contributing factor in the incidents. Some control measures were suggested accordingly.
