Abstract The quest to gain more knowledge of the subsurface and to reduce uncertainty in the interpretation of subsurface data has been an age-long effort in the oil and gas industry. To achieve this, asset owners use tools with improved resolution, utilize different types of logging tools and integrate the interpretation from these logging tools. This paper will review some projects where data from borehole imaging tools were used to support geosteering decisions and to gain more knowledge of reservoir structure. Borehole images are logs based on the circumferential measurement of a petrophysical parameter along a borehole wall. Logging-while-drilling borehole images can be used for structural, sedimentological and petrophysical analysis. These near-wellbore analyses contribute greatly to the success of most geosteering jobs. Geosteering is a process used in placing high-angled and horizontal wells in subsurface intervals of interest. It involves the use and integration of data from varied sources. This paper will show different scenarios, in different depositional environments, where borehole imaging supported the geosteering process and how geological interpretations from geosteering brought more clarity to borehole imaging analysis. Examples of these will highlight the stratigraphic relationship between geological structures and wellbore trajectory, detection of subsurface structural discontinuities, primary sedimentary structures, and the interpretation of complex geological structures. This paper will broaden our understanding of the applications of borehole imaging and how it integrates with geosteering in achieving oil and gas well objectives.

The purpose of the study is to improve the professional competence of students in the field of modeling technological processes in the oil and gas industry and performing strength calculations of the oil and gas equipment operation based on mathematical software (MathCAD). The research relies on the analysis of scientific and educational literature, generalization of the experience of specialized universities, comparative analysis of teaching methods used in the area, as well as a pedagogical experiment, which confirmed the effectiveness of the results achieved. The study resulted in the development of specialized courses (MathCad-based modeling of the technological equipment operation and Modeling of technological processes of the transportation of oil and gas products) based on the formulated mathematical problems for the MathCAD system, which effectively improved the professional competence of students in the field of modeling oil and gas production processes based on computer mathematics. The acquired competences can further contribute to the improvement of academic performance and more effective training of engineering students. The specialized courses and fundamental approaches to the use of mathematical software to facilitate the solution of engineering problems can be widely implemented in the learning process to train specialists in the oil and gas industry and related sectors.

In recent times, with the advent of exploSration activities in deeper hydrocarbon reserves, drilling of wells in HPHT conditions is one of the most studied field in the upstream oil and gas industry. Water-based fluids are the most common and frequently used drilling fluids oil and gas well construction. Although, water-based drilling fluids are environment friendly and relatively in-expensive, it is often associated with many problems when used in HPHT conditions. In order to overcome these problems in such viable conditions, modified surfactants are used with the mud to counteract the problems associated with it. This paper discusses the different applications of anionic and non-ionic surfactants in water-based drilling fluids both in laboratory and field scales. The paper also discusses the mechanisms of the surfactants and the effect on various mud properties to overcome hole problems like wellbore instability, rheology and filtration loss, foaming and flocculation of mud.

PT ABC is a subsidiary of PT PXZ (state owned companies under SKK Migas and PT Pertamina supervision) which is engaged un upstream sector in Indonesia. Seeing the continuing decline in oil and gas reserves in Indonesia and increasing demand, the government request all upstream company to find more source. PT ABC is trying to continue to increase production of oil and gas by opening a new potential project. Revenue sharing will use the gross split method. The purpose of writing this final project is to help PT ABC analyze new projects that will be undertaken. The analysis is carried out by looking at the business situation externally and internally and will be followed by economic analysis and risk analysis to identify the factor that has impact of the project. External analysis shows that the oil and gas industry is still an attractive industry for the government to run and support. However, in its implementation the company have to follow the applicable regulations since oil and gas industry are one of the strategic industries. In addition to funding activities, PT PXZ as the holding company is in a healthy financial condition. The results of economic analysis on the PT ABC project show that this project can be implemented and will generate profits for the company. The NPV to be obtained is USD 46.701.182, the IRR obtained is 17.15%, PBP will last for 5.52 years, and the PI has a value of 1,98. From the risk analysis, there are several factors that affect the economic results of the project, namely the price of oil and gas, the percentage of oil and gas sales, capital expenditure, and the percentage of oil and gas split.

Federal tax revenues from the main sectors of the Russian economy after the 1998 crisis are examined in the article. Authors present the structure of revenues from these sectors by main taxes for 1999-2003 and prospects for 2004. Emphasis is given to an increasing dependence of budget on revenues from oil and gas industries. The share of proceeds from these sectors has reached 1/3 of total federal revenues. To explain this fact world oil prices dynamics and changes in tax legislation in Russia are considered. Empirical results show strong dependence of budget revenues on oil prices. The analysis of changes in tax legislation in oil and gas industry shows that the government has managed to redistribute resource rent in favor of the state.
