Oil and gas drilling and development is witnessing new and inventive techniques targeted at increased production from difficult and aging wells. As depth of an oil or gas well increases, higher temperatures and harsher environments are encountered. Suitable elastomers can provide good sealing as they possess good resistance to heat and chemical attack, and as they are widely availability at low cost. In comparison with metals, elastomers are lighter in weight and lesser in stiffness and hardness, swell more with increasing temperature, and are usually better in corrosion resistance. Other reasons for their preference include excellent damping and energy absorption, more flexibility and longer life; good sealing even with moisture, heat, and pressure; negligible toxicity; good moldability; and flexible stiffness. As mentioned in chapter-1, swelling elastomers or gels have found extensive use in different applications including drug delivery, microfluidics, biomedical devices, scaffolds for tissue engineering, biosensors, etc. As the main focus of this book is the oil and gas industry, implementation of swelling elastomer technology and deployment in different petroleum applications are discussed below.

The article deals with the key issues concerning the system of security of fixed assets at the enterprises of the oil and gas industry. The purpose of the article is to investigate the fixed assets features and composition at the the enterprises of oil and gas industry, to determine the approaches to their assessment at the stage of their receipt by the enterprise. The state, dynamics of value and the degree of depreciation of fixed assets in Ukraine for the year 2017 have been analyzed, their features have been distinguished at the enterprises of different branches of the economy. To ensure the effective operation of the enterprises of the oil and gas industry, significant assets are required, and the results of their activities to a large extent depend on the availability and condition of fixed assets that ensure economic sustainability of economic entities. Oil and gas companies include pipelines and related equipment in fixed assets, oil and gas assets, machinery and equipment, buildings, buffer gas, drilling and reconnaissance equipment and other fixed assets. Among the assets of NJSC "NAFTOGAZ OF UKRAINE" for the year 2017, non-current assets occupied 86% of the total assets of the company, of which 94% were fixed assets, what determines the reliability of their accounting as an important element of effective management of enterprises. The dynamics of value and composition of fixed assets of enterprises of the oil and gas industry of Ukraine for 2016-2017 have been determined according to separate economic segments. The cost of fixed assets of NJSC "NAFTOGAZ OF UKRAINE" as of December 31, 2017 amounted to UAH 491 482 million, respectively, according to economic segments, it is structured in such a way that their largest share is concentrated in the system of transportation and distribution of natural gas - almost 48%, for storage of natural gas - 34%, production and sale of natural gas - 12%, and the rest belongs to the economic activities related to oil: the production of crude oil and gas condensate, transportation of crude oil. The composition of fixed assets of extractive enterprises differs from their composition in refineries. Industrial features of mining industry with significant volumes of work related to the disclosure of layers of minerals are characteristic to chemical production with a significant cost of equipment. The main approaches to the evaluation of fixed assets objects at the stage of their entrance to the enterprise have been investigated. The reliability of the accounting information on fixed assets depends on their assessment. When they are received, they are valued at their original cost, that is, by the amount of cash paid or their equivalents or fair value, another form of indemnity granted to obtain the asset at the time of its acquisition or creation, or, if accepted, the amount that is distributed to that asset in the original recognized in accordance with the specific requirements of other IFRSs. After recognition, the entity should choose either a cost model or a revaluation model in its accounting policies and should apply this policy to the entire group of fixed assets. A cessation of recognition occurs after the release of an object or when it does not expect future economic benefits from its use or disposal. In this case, it is recognized as profit or loss.

The ability to measure large amounts of data at high frequency, and the increasing ability to process these data close to the source at the edge, has opened up a new frontier in asset management. Until now, analysis of high-frequency data in real time has been the domain of a few, very expensive devices. However, this is rapidly changing, with the increasing capabilities of sensors and edge devices providing flexible, low-cost solutions that can be deployed across all site machinery to provide predictive and detailed information about these assets. All machinery vibrates at multiple frequencies when running. If you listen to this vibration, it can tell you a lot about the condition of the machine and its components. In fact, it is surprising how rich and detailed this information can be. Cavitation, insufficient lubrication, failing bearings and faulty impellers all have different vibration signatures, and by listening for these signatures it is possible to identify issues before they occur, and even predict when they will occur. It is also possible to feed this information (e.g. cavitation) to the control system so that process decisions can be made to avoid machine damage. This paper discusses solutions that are available now and currently being developed in terms of edge computing devices and advances in the algorithms that analyse the vibration data, and how they can be applied in the oil and gas industry to ensure assets are optimised and downtime is minimised.

Abstract Motivated to develop faster and faster contemporary society has been using more and more fossil and energy resources that can, unfortunately, cause environmental accidents. Petroleum is responsible for providing different products derived as lubricating oil widely used in different production chains and object of study of the work in question. Many environmental problems faced by the Oil and Gas Industry are associated with leaks, accidents and irregular discharges. Thus an alternative for cleaning and adsorption of oil spilled in the sea is presented the validity in this article: the rice husk, being the main objective of this article to prove its effectiveness with lubricant oil adsorbent. It was used as a low cost alternative adsorbent. Performing physical order treatments such as heating and using acid and base that could increase their efficiency. Some COD and Fitoxicity tests of the generated effluent were performed and analyzed during the work, generating excellent results related to the adsorption of lubricating oils, showing a total adsorption of 6.15 g / g when treated in basic medium and 4.7 g / g in acid medium.

The seismic method has been thriving in the oil and gas industry for decades. Technological progress in acquisition, processing and interpretation have made it practically the only geophysical method used for petroleum exploration. Unfortunately, gravity, as a pioneering geophysical method appears to have been completely forgotten in Australia’s oil and gas industry. Most of the gravity data in Australia were collected in the 1960s and 1970s. Only government agencies and a few exploration companies have conducted gravity surveys in petroleum basins since that time. Australia’s mostly flat terrain, economical aspects of the gravity method such as low cost and the ability to cover vast underexplored onshore basins in the country, all seem to be positive factors indicating that this method should be commonly used as a part of petroleum exploration. Given the petroleum industry is currently trying hard to make exploration more economically effective, this may be an opportunity to revive the gravity method in petroleum exploration.

This paper points to the importance of studying the intersection of public policy debates, spatial practice, and land use by applying Henri Lefebvre's spatial trialectic in a critique of the ongoing debate over hydraulic fracturing in western Pennsylvania. In this case study, the oil and gas industry appropriates established environmental justice discourses to assert that (1) fracking is clean and environmentally responsible, (2) it will help sustain local families and communities for many generations to come, and (3) fracking locally results in scalar, global benefit. Furthermore, the industry employs ad-hominum attacks and debunking strategies to frame anti-fracking activists as impractical alarmists. Through this rhetorical representation of space, the industry defines the process and associated values of fracking as desirable, inevitable, and most importantly, a sustainable process with just outcomes. Ultimately, the material reality of how the risks and benefits are distributed across the local, national, and global landscape through spatial practice is masked. Focusing exclusively on discourse ignores the real material conditions that give rise to and result from that discourse. Therefore, we argue Lefebvre's (1991) trialectic offers a way to address the interplay between representations and discourses of space and material reality.

Microseismic monitoring of hydrocarbon fields is one of the promising areas of modern seismology. In recent years, the methodology of microseismic monitoring for seismic emission has been actively developing in the oil and gas industry in order to study the impact of various technogenic processes on the hydrocarbon (HC) fields being developed. The technology does not require powerful sources of sounding signals, but uses constantly existing weak seismic fields of artificial or natural origin. During the development of the field, periodic monitoring of the intensity and spatial position of the zones of microseismic activity allows controling the behavior of HC deposits in order to optimize their development. Distinctive features of this technology are high mobility, fast deployment time, high resolution, and low cost of receiving, transferring and processing of microseismic data. The purpose was to analyze the results and evaluate the effectiveness of MFHF using microseismic monitoring of seismic emission processes. The results were obtained with the help of quantitative microseismic monitoring of seismic foci occurring successively near the well ports at different times during MFHF.

Abstract The Department of Petroleum Resources, Nigeria's oil and gas industry regulator, is an opportunity provider and business enabler. Using regulatory instruments such as Licenses, Approvals and Permits, the Department has enabled investors to unlock opportunities in the Upstream, Midstream and Downstream sectors of the industry. The Oil and Gas Industry Service Permit (OGISP) is a mandatory requirement for all service providers rendering or engaged to render technical service to the industry, in accordance with section 60A of the amended Petroleum (Drilling & Production) Regulations, 1988. Since its establishment, the Department has issued over a million permits to service providers in various areas of specialization. This paper examines the OGISP system framework; OGISP application process and requirements for permit issuance; benefits of OGISP to the industry and the Nigerian economy; and recommendations to improve the OGISP system.

Abstract Geothermal drilling has increased in the recent years with the renewable energy initiatives. Geothermal plants provide more than 6% of California's electricity. A large sum from the development budget is consumed by the drilling. This paper systematically analyzes and reviews the drilling activities and operations in a geothermal venture in Hawaii for more than 20 years to enhance the drilling operations and save costs. The paper starts by studying the geology of the area, which is located in an active volcanic region. Then, an extensive data collection was performed that went back to more than 20 years. The data was preprocessed and cleaned to be used in the analysis. The well designs were analyzed and the distribution of the drilling time was determined. After that, the performance of the geothermal drilling was benchmarked with the oil and gas drilling and the geothermal drilling in different parts around the world. The geology of the area is challenging with basaltic formation and tectonic movements. Volcanic eruptions that leads to closing wells were encountered in the recent years. As for the drilling, six challenges were identified and deeply analyzed. These challenges include: lost circulation, stuck pipe, cementing, low rate of penetration (ROP), logistics issues, and safety concerns. Each of these challenges was intensely investigated and solutions were proposed. The benchmarking with the oil and gas industry and other geothermal drilling operations shows that the geothermal drilling operations can be enhanced significantly. This improvement in the drilling in the geothermal venture will result in huge cost savings. A set of recommendations to improve the performance is presented as new organizational and workflow changes, analysis and elimination of nonproductive time (NPT), and novel engineering redesigns.
