The need to maintain the level of production and an acceptable cost of developing oil and gas fields forces us to rely primarily on the existing reserve, that is, to maximize the potential of traditional oil and gas production regions and adjacent territories - the marginal zones. At the same time, it is necessary to develop unexplored sedimentary complexes at depths of more than 3-5 km. Against this background, it is necessary to highlight a special phenomenon that increases the oil and gas potential of the subsoil associated with trap magmatism. The insufficient level of knowledge of the subsoil makes it possible to predict the discovery of large oil and gas deposits of the traditional type, which will ensure their high profitabilitye. Keywords: trap magmatism; profitability of oil and gas resources; marginal zones; hornfels; transformation of carbonates; rocks of trap formations; regional seals.

According to forecast estimates, the depletion of continental oil and gas fields of the Russian Federation is 30 - 50%, and the fields of the continental shelf are less than 1%. Therefore, the main volumes of growth of reserves, oil and gas production in the fuel and energy complex system should be planned at the expense of resources and reserves of the continental shelf. The article considers the principal features of development of oil and gas fields of the continental shelf and criteria determining types of offshore oil and gas fisheries.

A research and comparison of natural and damaged (due to the active development of oil and gas fields) permafrost soils in the Jamalo-Nenets Autonomous Okrug were carried out. The analysis was run of correlation between an average monthly temperature of air, an average monthly sum of precipitation, the weight humidity and the thickness of the seasonal thawed layer. The conclusions were drawn about a poor resistance of landscapes on the permafrost rocks to the anthropogenic interventions, which in its turn is accompanied by the cryogenic processes and unfavorable influences on the Extreme North biosphere.

AbstractOnshore exploration success during the first half of the 20th century led to petroleum production from many, relatively small oil and gas accumulations in areas like the East Midlands, North Yorkshire and Midland Valley of Scotland. Despite this, the notion that exploration of the United Kingdom's continental shelf (UKCS) might lead to the country having self-sufficiency in oil and gas production would have been viewed as extremely fanciful as recently as the late 1950s. Yet as we pass into the new century, only thirty-five years on from the drilling of the first offshore well, that is exactly the position Britain finds itself in. By 2001, around three million barrels of oil equivalent were being produced each day from 239 fields. The producing fields have a wide geographical distribution, occur in a number of discrete sedimentary basins and contain a wide spectrum of reservoirs that were originally deposited in diverse sedimentary and stratigraphic units ranging from Devonian to Eocene in age. Although carbonates are represented, the main producing horizons have primarily proved to be siliciclastic in nature and were deposited in environments ranging from aeolian and fluviatile continental red beds, coastal plain, nearshore beach and shelfal settings all the way through to deep-marine, submarine fan sediments. This chapter attempts to place each of the main producing fields into their proper stratigraphic, tectonic and sedimentological context in order to demonstrate how a wide variety of factors have successfully combined to produce each of the prospective petroleum play fairways and hence, make the UKCS such a prolific and important petroleum province.

The article touches upon the problem of technogenic risks arising in the course of building and operating oil and gas complexes in the Caspian Sea taking into account the adoption of the Con-vention on the legal status of the Caspian Sea and regulation of the territorial division of the Caspian Sea. Technological risks are presented from the position of safety of industrial facilities in the offshore area and in the coastal zone, the impact of these facilities on the ecology of the Caspian is considered. The risk analysis was carried out taking into account world experience, as well as incidents that occurred at the offshore oil and gas production facilities in the Caspian Sea. There has been presented the layout of oil and gas fields at the bottom of the Caspian Sea and the division of the bottom based on adopting the Convention. A general description of the Caspian Sea has been given; unique features of the Caspian and the most unexplored seismic effects have been stated. It has been recommended to conduct a comprehensive assessment of the state of the seabed according to seismological, mud, volcanic and engineering-geological conditions; to develop measures for preventing and reducing the damage from hazardous natural processes and exploitation of oil and gas fields; to forecast the fluctuations of the Caspian Sea level, taking into account today’s economic activity; to study the natural and technogenic factors determining the environmental safety of the Caspian Sea; to monitor seismic phenomena, crustal movement in zones of tectonic faults at the sea bottom, etc. The speed and direction of wind currents in the Caspian Sea have been analyzed. The maps of mud volcanoes location in the Caspian basin (located on land, hidden and identified by seismic, geological, geophysical and geochemical methods, etc.) are illustrated. Conclusions are made about the high risks for developing hydrocarbon deposits in the Caspian Sea basin. There is the need to take into account environmental requirements and standards, to use modern technologies, to prevent incidents at offshore oil and gas production facilities.

Decommissioning offshore oil and gas production facilities have been progressively increasing the concern of the industry, government and other interest groups through the last years. There are at least two reasons for this sudden regard. First, it is the maturing of several oil and gas fields around the world in recent years. Second, it is the growing impact of environmental concerns in international affairs. Despite several works published address to some techniques and to potential problems and risks related to decommissioning offshore oil and gas production installations its procedures are in some extent an innovative issue, especially in Brazil. Therefore, the motivation of this paper is the novelty of the subject in Brazil, since the national industry is just beginning to deal with the end-of-leasing obligations, which involve decommissioning operations. The main ambition is to stimulate debate about appropriate issues.

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

The depth and scale of man-made transformations of steppe landscapes in the course of oil and gas production remain underestimated. The sites provided for the development of oil and gas fields are not allocated to a separate category of the Russian Land Fund . Often there is a mismanagement of subsoil companies to the plots provided to them, provoked by the loyal attitude of the Supervisory authorities. Approved projects of oil and gas development often demonstrate minor significance of section on assessing the impact on the environment. Optimization of this type of land use becomes necessary at this stage of oil and gas production development.

Technical Measures

To increase the efficiency of hydrodynamic well testing after the geological and technical measures, it is proposed to record the pressure change at the bottom of the well during the development by means of the GIC. Such a solution will allow to combine the process of well development after the IPF with the study, thereby increasing the control over the success of the repairs carried out without additional downtime in real time.
