Gravitational Anomalies

Based on the analysis of published materials, it is noted that the degree of connection between the indicators of the anomalies of the gravitational field and oil and gas content remains unclear. The aim of the research was to study the nature of the dependence and assess the degree of connection between the size and location of oil and gas fields with gravitational anomalies using the example of the Fergana oil and gas region. To solve this problem, the published material on the geological structure and data on the sizes (effective volume) of deposits, as well as data on deep anomalies of the gravity field in the Fai reduction, were used. The study involved about 70 deposits. Analysis of variance showed that the “influence” of the deep anomaly factor on the effective volume of the fields in the Fergana depression is significant and reliable with a probability of 0.99. At the same time, the share of the influence of this factor on the effective volume of oil deposits in relation to the total impact of all factors is 42%, and for oil and gas - 62%. This testifies to the significant influence of deep subcrustal processes that create corresponding gravitational effects on the formation of the size and location of oil and gas fields in the Fergana depression. According to local gravity anomalies, the impact on the location and effective volumes of deposits is significant, but the reliability is low. The degree of influence on them remains unclear. The results obtained can be used to develop methods for forecasting promising areas for performing high-priority geological exploration works.

X-ray structural studies have shown that with the increase of the life of the pipes, the surface layers of the metal adsorb a significant amount of gases (hydrogen, oxygen and sulfur), especially this is strongly manifested in the field of corrosion defects (ulcers, pitting). Also, it was found that in the process of long-term operation, the metal of the pipe walls is heavily flooded, which directly leads to its brittle and, as a consequence, increased hardness and reduced ductility. Such studies are unique in the subject of corrosion-mechanical resistance of metal and its degradation during long-term operation in the presence of alternating loads and at the same time, the aggressive environments of oil and gas fields.

The article deals with the research of the potential of oil-and-gas content within the Western Ukrainian oil and gas region.  The main directions and ways of increasing oil and gas production are determined. Consequently, the discovery of new hydrocarbon fields is the major direction to boost oil and gas production. The issue of the discovery of new oil and gas fields is suggested to divide into the following directions: a search for oil and gas fields at shallow depths (short-term prospect), a search for oil and gas fields at mid-depths and a search for oil and gas fields at great depths (the main prospects of increasing oil and gas production). The geological and geophysical data were thoroughly analyzed throughout structural and tectonic units within the Western region of Ukraine with the aim of substantiating the prospects of their oil-and-gas content and introduction of new directions of oil-and-gas exploration. The prospects of oil-and-gas content of the Neogene and the Mesozoic deposits of the exterior of the pre-Carpathian depression and flysch of the interior of the pre-Carpathian depression are provided. The prospects of oil-and-gas content of the Cretaceous and the Paleogene deposits of folded Carpathians are characterized. The promising directions for further oil-and-gas exploration within indicated tectonic elements of Carpathian region are identified; the top priority project sites are suggested. Wildcat drilling and further oil-and-gas exploration are strongly recommended for all identified project sites. The research has identified the most promising exploration project sites. All of them are illustrated with appropriate maps and cross-sections. Thus, the most promising ones at shallow depths (up to 2000 m) are the following ones: South-Slyvkinske, Anhelivka, Hoshiv and Verkhnii Hutyn elevations. At mid-depths there are Pechenizhyn, Kliuchiv, Uhilnia and Boratychi elevations. At depths over 4000 m there are the following ones: Horodyshche structure, Posada, Dubliany, South-Lopushnia, Biskiv, Sloboda-Dolyna and Mizhrichchia elevations, Pidrezhzhia and Dobromyl-Strilbychi structures. The assessment of the resource potential of identified exploration project sites was done.

The Impact

In the process of extraction, collection, transportation and primary processing of hydrocarbons, the lands of the fields are often damaged. For the further operation of the oil field, it is necessary to carry out not only reclamation of disturbed lands, but also oil-contaminated lands formed as a result of accidental spills. The natural environment of Western Siberia is a fragile environment and interference in its existing balance as a result of accidental spills of oil products and pollution of land and water bodies leads to negative consequences for the flora and fauna. If the impact on the natural environment during the development of oil and gas fields during the placement of oil field facilities can still be considered as permissible, then the ingress of oil products into the environment should be considered as negative with far-reaching consequences.

Reliance Industries Ltd. (RIL), the largest private sector company in India, invested in oil and gas fields by winning the bid under New Exploration and Licensing Policy in the year 1999 and aspired to exploit the growing Indian energy market. Though RIL developed the KG-D6 gas blocks in record time, soon after, it was engulfed with some issues like lack of technical expertise, geological complexities and huge capital expenditures. To tackle these issues RIL was hunting for a partner with technical expertise. Meanwhile, British Petroleum (BP) was also grappling with some serious hurdles and eyeing for a new market. India was the best bet for BP as it has recognized the potential of the subcontinent and its earlier stint with RIL inspired BP to invest in India. This case study analyses whether the much-anticipated deal was successful or not. This case study discusses the entire background, issues and difficulties encountered by RIL and BP prior to the deal. Further, we investigate the impact of the deal on RIL by analyzing its operational efficiency, financial performance and stock gains in the pre and post period of the alliance. This is an analytical case study based on the secondary databases, where it analyses the various pros and cons of the alliance between RIL and BP.

Abstract The purpose of conducting this LCA was to calculate the potential environmental impacts of the repurposing of John Lawrie Tubulars products sourced from North Sea Oil and Gas fields and to compare repurposed steel tubulars to those made from prime steel1throughout their lifecycle. The analysis includes multiple environmental characterization indicators associated with the material processing, on-site operations, and supply chain. The benefits of repurposed tubulars are consistently beneficial across all environmental indicators when compared to prime steel tubulars. The life cycle analysis results show that for every tonne of steel tubular repurposed there is a 97.21% saving of carbon emissions over a prime steel seamless equivalent and is 97.78% for welded steel tubulars (cradle to gate). Further characterization analysis (cradle to site) showed that distribution presented the highest impact (47%) with materials (26%) and material transportation (15%). The average delivery in the UK adds 56.53kgCO2eto John Lawrie's tubular steel giving a cradle to delivery at the customers gate of 118.53kgCO2eper tonne2. The combined material and distribution carbon footprint of repurposed tubular products (cradle to site) has ~6% of the impact of those made from prime steel. With growing pressure on the construction industry amongst others to be more resource efficient, and to lower embodied carbon, material reuse strategies are critical to meet targets. Considering the potential of the results for environmental impact reduction there is the need to further develop and promote the application of repurposed steel tubulars. This data can be used to demonstrate the environmental impacts and benefits of refurbished tubulars and supports the efficacy of environmental claims and contribution to circular economy. With both the construction and energy industries focused on finding innovative ways in which to reduce their emissions and support the Scottish and UK Governments in bringing all greenhouse gas emissions (GHG) to net zero by 2050, this study details one way these industries can help drive the changes required.
