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.

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.

The authors discuss recent developments in oil and gas production in Newfoundland and Nova Scotia and the legal and regulatory regimes which affect both interest holders and oil and gas practitioners. The authors pay particular attention to jurisdictional issues arising from the intersection of federal and provincial legislation and clarify when particular legislation does or does not apply. The authors then examine the legal requirements for the approval of and implementation of oil and gas development plans, the impact of provincial royalty and tax regimes on development, and the criteria for the granting of significant discovery licenses. Finally, the authors discuss the roles of provincial and federal bodies with respect to regulatory and environmental inter-jurisdictional issues.

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 boom in Australian oil and gas development continued in 2013, with record overall investment of $60 billion. This investment resulted from spending on the seven LNG projects under development, together with that on numerous other oil and gas developments. These projects are expected to collectively contribute up to 665 million barrels of oil equivalent (MMboe) to Australia’s oil and gas production, which totaled 513.8 MMboe in 2013. LNG, presently Australia’s seventh largest export, is likely to soon rival the nation’s largest export, iron ore. By the end of 2013, three of the LNG projects under construction—Gorgon, Queensland Curtis LNG (QCLNG) and Gladstone LNG (GLNG)—were more than 70% complete; first LNG will be before the end of 2014 for QCLNG and in 2015 for Gorgon, GLNG and Australia Pacific LNG (APLNG). The other three LNG projects—Wheatstone, Prelude and Ichthys—are close behind. These new LNG projects follow Pluto, Australia’s third LNG project, which commenced production in 2012. A full year of production from Pluto drove increased gas production in 2013. Woodside also completed the North Rankin redevelopment and continued development of the Greater Western Flank, both of which will extend the life of the North West Shelf (NWS) project. A number of other projects also commenced production. In the Carnarvon Basin, oil production began at Santos’s Fletcher-Finucane Field, and at BHP Billiton’s Macedon project, domestic gas production started. In the Timor Sea, PTTEP’s Montara Field began production of oil. In Victoria, the ExxonMobil Kipper-Turrum-Tuna project came online, with the production of gas from Tuna and oil from Turrum. Production of gas from Origin Energy’s Geographe Field (as part of the Otway Gas Project) commenced in mid-2013. Onshore oil production grew in 2013, with the Cooper-Eromanga Basin now producing more oil than any other onshore Australian basin. A major effort is underway to increase production from the western flank oil trend and to develop both the conventional and unconventional gas fields in the Cooper Basin. Spending on the development of new projects probably peaked in 2013 and there is growing concern about a dearth of future projects, with expansion of existing LNG projects and development of new projects being pushed back due to a combination of increased costs and growing international competition. There are also ongoing industry concerns about impediments to onshore gas exploration and development generally.

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.
