Abstract The role of the Caspian Sea in the development of the oil and gas industry for our country and the world is undeniable. The discovery of new fields creates conditions for the development of efficient and modern technologies. The need for energy causes us to move away from the shore day by day and encounter bigger obstacles with increasing depth. Gunashli field sites are located 120 km from the shore and at a depth of 80-150 m. Studies have shown that during the inter-site transport of low pressure gas, mechanical impurities and gas leaks accumulate in the part of the pipeline rising from the seabed to the platform, which prevents the flow of gas to the low pressure compressor station. Low-pressure gas enters the compressor station with liquids and mechanical mixtures, which leads to rapid wear and tear of the working parts of expensive compressor machines. Initially, according to d'Alambert principle, the forces acting on liquid and solid particles in a vertical pipe were investigated, then the results are shown. Due to this results, we have proposed a new design for cleaning the gas at the bottom of the sea and transferring it to the separator.

The Impact

The article discusses issues related to the impact of climate change on the objects of the oil and gas industry. The main trends in climate change on a global and regional (on the territory of Russian Federation) scale are outlined. Possible approaches to the identification and assessment of climate risks are discussed. The role of climatic risks as physical factors at various stages of development and implementation of oil and gas projects is shown. Based on the example of oil and gas facilities in the Tomsk region, a qualitative assessment of the level of potential risk from a weather and climatic perspective is given. Approaches to creating a risk management and adaptation system to climate change are presented.

As the Atlantic Canadian oil and gas industry continues to mature, offshore regulators face new and varied issues as they work to implement the objectives of the Atlantic Accords. Laws that were largely developed before the Atlantic Canadian offshore contained producing projects are now being applied to a diverse and evolving industry. As is often the case, laws, as expressed on paper, can prove difficult to apply to each unique set of circumstances that arises in practice.Fundamentally, many of the powers of the Atlantic Canadian offshore regulators rely on the concept of “waste.” An offshore regulator can order a company to commence, continue, or increase production of petroleum where it is of the opinion that such an order “would stop waste.” Conversely, the regulators may order a decrease, cessation, or suspension of the production of petroleum for the same reason. In certain situations of “waste,” the Accord Acts provide for a “forced marriage” via compulsory unitization.While “waste” is instrumental to the authority of the offshore regulators, by necessity its definition is open to some interpretation. This article will explore various interpretations of “waste,” and examine the role of waste in the Atlantic Canadian offshore regimes.

Integrated Operations

The concept of a capability platform can be used to argue how firms engage networked relationships to embed learning/performance into distinctive practices rather than focusing only on technology. In fact the capability language allows us to unpack the role of technology by emphasizing its interaction with people, process, and governance issues. The authors address the importance of a capability approach for Integrated Operations and how it can improve understanding of how people, process, technology, and governance issues are connected and managed to create scalable and sustainable practices. The chapter describes the development of capabilities as something that is happening within an ecology. Using ecology as a metaphor acknowledges that there is a limit to how far it is possible to go to understand organizations and the development of capabilities in the oil and gas industry as traditional hierarchies and stable markets. The new challenge that has emerged with integrated operations is the need for virtual, increasingly global, and network based models of work. The authors couple the ecology approach with a capability platform approach.

Categorization Model

Gas leaks in the oil and gas industry represent a safety risk as they, if ignited, may result in severe fires and/or explosions. Unignited, they have environmental impacts. This is particularly the case for methane leaks due to a significant Global Warming Potential (GWP). Since gas leak rates may span several orders of magnitude, that is, from leaks associated with potential major accidents to fugitive emissions on the order of 10−6 kg/s, it has been difficult to organize the leaks in an all-inclusive leak categorization model. The motivation for the present study was to develop a simple logarithmic table based on an existing consequence matrix for safety related incidents extended to include non-safety related fugitive emissions. An evaluation sheet was also developed as a guide for immediate risk evaluations when new leaks are identified. The leak rate table and evaluation guide were tested in the field at five land-based oil and gas facilities during Optical Gas Inspection (OGI) campaigns. It is demonstrated how the suggested concept can be used for presenting and analysing detected leaks to assist in Leak Detection and Repair (LDAR) programs. The novel categorization table was proven valuable in prioritizing repair of “super-emitter” components rather than the numerous minor fugitive emissions detected by OGI cameras, which contribute little to the accumulated emissions. The study was limited to five land based oil and gas facilities in Norway. However, as the results regarding leak rate distribution and “super-emitter” contributions mirror studies from other regions, the methodology should be generally applicable. To emphasize environmental impact, it is suggested to include leaking gas GWP in future research on the categorization model, that is, not base prioritization solely on leak rates. Research on OGI campaign frequency is recommended since frequent coarse campaigns may give an improved cost benefit ratio.

Sand Control

Summary In many industrial processes, an effective particle–filtration system is essential for removing unwanted solids. The oil and gas industry has explored various technologies to control and manage excessive sand production, such as by installing sand screens or injecting consolidation chemicals in sand–prone wells as part of sand–management practices. However, for an unconsolidated sandstone formation, the selection and design of effective sand control remains a challenge. In recent years, the use of a computational technique known as the discrete–element method (DEM) has been explored to gain insight into the various parameters affecting sand–screen–retention behavior and the optimization of various types of sand screens (Mondal et al. 2011, 2012, 2016; Feng et al. 2012; Wu et al. 2016). In this paper, we investigate the effectiveness of particle filtration using a fully coupled computational–fluid–dynamics (CFD)/DEM approach featuring polydispersed, adhesive solid particles. We found that an increase in particle adhesion reduces the amount of solid in the liquid filtrate that passes through the opening of a wire–wrapped screen, and that a solid pack of particle agglomerates is formed over the screen with time. We also determined that increasing particle adhesion gives rise to a decrease in packing density and a diminished pressure drop across the solid pack covering the screen. This finding is further supported by a Voronoi tessellation analysis, which reveals an increase in porosity of the solid pack with elevated particle adhesion. The results of this study demonstrate that increasing the level of particle agglomeration, such as by using an adhesion–promoting chemical additive, has beneficial effects on particle filtration. An important application of these findings is the design and optimization of sand–control processes for a hydrocarbon well with excessive sand production, which is a major challenge in the oil and gas industry.
