Abstract The Liza Phase 1 development project, offshore Guyana, is an unique example of what the offshore oil and gas industry is capable of when working together to deliver a common objective. ExxonMobil and the Stabroek Block co-venturers, Hess Guyana Exploration Limited and CNOOC Petroleum Guyana Limited, commenced oil production from the Liza Destiny floating production, storage, and offloading (FPSO) vessel in December of 2019, less than 5 years from the initial discovery of hydrocarbons in the Staebroek block. With the production and export of its first barrels of oil, the project completed the establishment of a nascent oil and gas industry in Guyana that is poised for tremendous growth in the coming years. The Liza Phase 1 development consists of a 120 kbd conversion FPSO (The Liza Destiny) and a network of subsea infrastructure to produce from and inject in two drill centers. It is expected to develop a resource of about 450 MBO gross estimated ultimate recovery. The water depth ranges from 1,690–1,860 m throughout the development which is located approximately 200 km offshore Guyana. This paper highlights the scope and pace of the project and discusses three specific challenges overcome: the uncertainty of the metocean conditions, extending the application of the selected riser technology, and executing in a challenging and frontier offshore location. A key to the success of the project was the unified approach between stakeholders and the commitment to act as One Team. The Liza Phase 1 project rapidly developed a newly discovered deep water resource in a frontier location while overcoming numerous challenges. By delivering Guyana's first ever oil production among industry leading cycle times, the Liza Phase 1 project has set the foundation for the future of deep water developments in Guyana.

Currently the oil and gas industry is focusing on challenging deep water projects, particularly in Campos Basin located coast off Brazil. However, there are a lot of prolific reservoirs located in shallow water, which need to be developed and they are located in area very far from the coast, where there aren’t pipelines facilities to export oil production, in this case is necessary to use a floating production unit able to storage produced oil, such as a FPSO. So, the riser system configuration should be able to absorb FPSO’s dynamic response due to wave load and avoid damage at touch down zone, in this case is recommended to use compliant riser configuration, such as Lazy Wave, Tethered Wave or Lazy S. In addition to, the proposed FPSO for Tubarão Martelo development is a type VLCC (Very Large Crude Carrier) using external turret moored system, which cause large vertical motion at riser connection and it presents large static offset. Also are expected to install 26 risers and umbilicals hanging off on the turret, this large number of risers and umbilicals has driven the main concerns to clashing and clearance requirement since Lazy-S configuration was adopted. In this paper, some numerical model details and recommendations will be presented, which became a feasible challenging risers system in shallow water. For instance, to solve clashing problem it is strictly recommended for modeling MWA (Mid Water Arch) gutter and bend stiffener at top I-tube interface, this recommendation doesn’t matter in deep water, but for shallow water problem is very important. Also is important to use ballast modules in order to solve clashing problems.

The oil and gas sector is an important factor in sustainable development, so it is considered necessary to make serious changes in conducting economic analysis on the oil and gas business. Oil and gas industry activities consist of upstream activities, and downstream activities. Activities in these upstream and downstream operations have high risk, high costs and high technology, so the company continuously tries to reduce the importance of the adverse impact of these risks on the work environment and people. Thus, evaluating the factors that affect sustainable production in this sector becomes a necessity. In this research will be evaluated the economy of the oil and gas field using methods of economic indicators, among others; NPV, POT, ROR, where these factors are estimated in order to be able to estimate the prospects of the oil and gas field so that the decision that the field development project can be implemented or cannot be taken immediately. Implementation of oil and gas field economic evaluation in this study using Macro VBA Excel. From several methods of economic analysis obtained that the results of this study show high precision compared to other methods, in addition to the way of evaluation using the above economic indicators is very popular.

Oil and gas production continues to be an important sector of Utah’s economy. Following a 25% loss in production between 2014 and 2015, Utah’s production continues to slowly rebound. Crude oil production in 2019 appears to be slightly ahead of 2018 production. Monthly production averages slightly over three million barrels, placing Utah among the top ten states in crude oil production. Along with the continuing increase in production, the state’s legal framework governing oil and gas continues to develop. This Article examines recent changes in Utah statutes and regulations along with new case law developments involving the oil and gas industry. In particular, this Article discusses a recent federal bankruptcy decision involving midstream agreements, the revision to a Utah statute that now requires mandatory reporting of unclaimed mineral interests, and recent revisions to Utah’s oil and gas regulations.

The oil and gas industry remains for Russia the most important source of income, a strategic industry. According to official figures of the Ministry of Finance of the Russian Federation, income from the oil and gas sector, according to the results of 2019, is 40% of the total budget of the country. A large volume of crude oil and gas is exported from the country. The tax burden on raw materials reaches up to 60% of the initial cost, which makes oil production at new fields extremely unprofitable. The most important direction for the country is the transition from a strategy for the sale of crude oil products to refined ones, which have an additional cost. The article discusses the features of domestic oil production, analyzes the reasons for overpriced in comparison with competitive raw materials from other oil producing leader countries. The strategy of ensuring the economic security of the industry is noted, the main tools are listed and the mechanisms for ensuring the economic security of petrochemical industry enterprises are presented.

Abstract This paper provides an overview of the work completed to design, qualify, manufacture and integrate electrical and optical double barrier penetrators with the Electrically Trace Heated Pipe-in-Pipe (ETH-PiP) as part of the Neptune Energy Fenja Development Project. Typical subsea penetrator systems in the oil and gas industry, such as pumps, compressors and X-trees are designed to be retrievable, to enable periodic refurbishment as well as providing the option for replacement, if required. However, the ETH-PiP architecture makes retrieval of system components complicated and uneconomical. Both the electrical and optical dual barrier penetrator system designs have to comply with a set of ETH-PiP specific criteria, such as to be maintenance free over a 25 years service life, prevent water ingress to the pipeline, provide pressure containment for operational media (in an unlikely scenario where the inner pipe bursts) and guarantee minimum footprint to allow an optimum integration onto the Pipeline End Termination (PLET) structure. In addition, the electrical system has to comply with a medium voltage rating (i.e. 5.0/8.7kV) to ensure a wide range of possible ETH-PiP architectures. The optical system has to maintain insertion loss below 0.5dB and a back reflection below -45dB to comply with the stringent requirements of distributed temperature monitoring sensor system over long distances. The qualification program of the electrical dual barrier penetrator system was performed in accordance with IEC 60502-4 and SEPS-SP-1001. A tailor made sequence had to be developed for the optical system, based on guidance from SEAFOM-TSD-01, considering that the system partly falls outside the associated standard application. The electrical dual barrier penetrator system qualification sequence was developed in two phases; firstly, the electrical transition contacts in the feedthrough chamber were qualified in accordance with IEC 60502-4 and secondly, four electrical double barrier penetrator prototypes were manufactured to allow the completion of the qualification sequence defined as per SEPS-SP-1001. The optical dual barrier penetrator system qualification employed the manufacturing of three prototypes to execute the pre-defined qualification sequence. Following the individual qualification of the electrical and optical dual barrier penetrator systems, subsequent welding and full-scale assembly trials were performed to ensure that the maximum allowable temperatures within the penetrators would not be exceeded during welding to the PLET, and to proof test the assembly procedure. Electrical verification testing was also undertaken during these trials to verify that the integrity of the penetrators had been maintained during the assembly and that the PLET arrangement did not give rise to any electrical stresses that could result in excessive deterioration of the penetrators. Integration of the four electrical and two optical dual barrier penetrator systems to the project PLET was completed in Q1 2020, with the actual subsea installation of the first ETH-PiP section including the PLET in Q3 2020.

Indonesia’s oil and gas industry is the huge contributor to government export revenues and foreign exchange and contributes a substantial amount to state revenue. However, the total of oil production declined around 4,41% per year since 2007, and the sharpest decline was in 2013. This situation gives impact to the performance of oil and gas industry, especially government revenues. Therefore, the purpose of this study is to measure the financial performance of Oil and Gas Industry and to examine the significance differences between the financial performance before and after the decline in oil and gas production. The data were collected from financial report and the period was divided into two periods, before the decline in production (2011 – 2012) and after the decline in production (2014 – 2015). Paired sample t-test and financial ratio analysis (FRA) were used to analyzed the data. The finding shows that the largest oil and gas company in Indonesia is still in good financial condition, although it gained loss. In addition, current ratio and return on equity had significance difference during the period of before and after a decline in oil and gas production. The authors believe that the findings will be helpful for managers who continuously attempt to explore opportunities to provide a higher return.

Rapid development of an oil and gas industry in the north of Western Siberia in the middle of the 20th century has demanded a significant amount of the electric power. This strategic task was carried out step by step in the neighborhood of Surgut (the largest oil and gas industry center on the Middle Priobye). Two gas-fired power stations have been consistently constructed. The integrated reservoir cooler has been built on the river Chernaya for cooling of circulating water in the system of reverse water supply of power plants. The article presents the assessment of consequences of flooding at construction of the Surgut reservoir. The total area of the water area of a reservoir is 2211 hectares, including 50% of forest, 20% of meadow, 5% of peat bog communities were under flooding. The authors of the paper develop the basic ecological map of the reservoir and neighborhood with the indication of natural and technogenic objects. Moreover they give the results of two years' monitoring of microbial community structure in the coastal zone of the reservoir cooler. They find it is important to provide the assessment of intensity of self-cleaning processes of the water object and analyze the sources of anthropogenic load on the water object. The microbiological methods which important to use for bio indication of an ecological condition of the Surgut reservoir have allowed to estimate the trophic status, to reveal ecologically unsuccessful sites of the water area, and to define intensity of self-cleaning processes in the water body.

This paper discusses the most important aspects of the development of the oil and gas industry in Russia. To replace declining oil production in Russia, we need to change the obsolete paradigm of the development of the domestic resource base. In the twenty-first century, the priority tasks in the search for oil deposits should be the Russian Arctic shelves and immature onshore provinces as well as unique unconventional oil accumulations (Bazhenov, Domanik, Khadum, Kuonamka Formations, etc.). In addition, special focus should be placed on the exploration of small and smallest oil and gas fields, which will be developed with the collaboration of small- and medium-sized oil businesses to ensure up to 20% of domestic oil production. The shift from extensive to intensive development of Russias oil and gas sector will require the prioritizing of technological tasks.
