As a commonly used chemical agent, surfactant is used to improve the efficiency of oil-and-gas exploitation. Since the conventional surfactant technology fails to meet the requirements of oil-and-gas resources exploitation currently, this paper deeply researches on the studies of cutting-edge technology of oil-and-gas exploitation, and learns the advanced experience from foreign countries. It aims to point out that the needs of China’s demand for oil-and-gas exploitation can be met with through technology innovation, preparation methods improvement and key technology mastery of surfactant in oil field.

Research relevance. Main Russian reserves, including oil and gas, are currently focused at northern and Arctic territories. Their exploration requires all necessary assets: labor, non-human, and financial. People employment for oil and gas deposits exploitation is connected with a drive-in drive-out method first of all. Personnel employment plan reliability should take into account the drive-in drive-out method development trends and existing contradiction overcoming. Research aim is to analyze the use of the drive-in drive-out method as applied to oil and gas fields development in the conditions of the North and Arctic by the example of the Yamalo-Nenets Autonomous District, determine the developing trends and existing contradictions requiring overcoming. Research methodology includes generalization and analysis of the data on drive-in drive-out method application, as well as the methods of matching, grouping, averaging, and analog. Results. In course of research the practicability of drive-in drive-out as a method of employing people for oil and gas resources exploitation. Time-dependent changes in the drive-in drive-out method application have been revealed (total and relevant number of workers, change in the composition of drive-in drive-out employees, the share of regional drive-in drive-out, and change in the composition of foreign labor). The prerequisites for the drive-in drive-out method have been formulated; they have first been conditioned on the lack of qualified workers among local population and the legacy of the Soviet period when the professional training of skilled personnel was not given due attention. The current situation with the drivein drive-out method of employing people is characterized by the distribution of drive-in drive-out workers across the territory of the Yamalo-Nenets autonomous district, depending on the location of the developed and potential oil and gas fields, as well as the historically formed contour of urban and rural settlements: the oil and gas producing south, the developed gas producing central regions, the transport and logistics hub with the mining Polar Urals, new arctic (peripheral) oil and gas producing regions, developing east 78 "Izvestiya vysshikh uchebnykh zavedenii. Gornyi zhurnal". No. 5. 2020 ISSN 0536-1028 and depressive southwest. The contradictory aspects of the drive-in drive-out method have been established. The practicability of drive-in drive-out from an economic point of view raises no objections. The social aspect is assessed negatively (the social aspect includes work organization, turnover, the sociopsychological situation; the medical aspect includes constant acclimatization and re-acclimatization). The negative impact on the growth of unemployment has not been confirmed. There must be no unreasonable limitation of the drive-in drive-out method, especially as the current situation will objectively require an increase in drive-in drive-out scale. Summary. Drive-in drive-out method of employing people for oil and gas resources exploitation is generally accepted and applied both in home and abroad. Drive-in drive-out scale should be noted. Under these conditions, in order to increase the reliability of investments plan related to the labor support of projects, it is necessary to take into account the identified trends in drive-in drive-out development and provide for measures to prevent or mitigate the identified contradictions of the drive-in drive-out method.

Abstract Conservation partners are concerned that oil and gas development in the Prairie Pothole Region may reduce the abundance of breeding duck pairs using associated wetland habitat. We conducted wetland-based surveys for breeding pairs of 5 species of dabbling ducks in the Bakken oil field during 2015–2017 across a gradient of oil and gas development intensity to test the hypothesis that the abundance of breeding duck pairs on survey wetlands would decrease as the development of oil and gas resources increased. We included covariates traditionally used to predict breeding duck pairs (i.e. wetland size and class) and a spatiotemporal index of disturbance when developing zero-inflated Poisson models relating pair abundance to environmental predictors. Similar to past analyses, pair abundance was strongly associated with wetland size. Our results were mixed and suggested that the abundance of early and late nesting species was positively and negatively related, respectively, to an index of disturbance that was largely driven by oil and gas development. Regardless of the direction of the relationship, effect sizes were small and not considered biologically significant. Our findings indicate that in our study area, strategies to conserve wetland resources for breeding duck pairs should not deviate from previous prioritization metrics within the range of oil and gas development we observed. We believe that our findings may have implications to similar landscapes within the Bakken.

AbstractThis paper examines the environmental history of petroleum pipeline canals and their impact on wetland loss in Coastal Louisiana, and how politics and wetland science have shaped restoration efforts over time. Since the 1930s, Coastal Louisiana’s wetlands have provided America with abundant oil and gas resources. The expansion of this vital energy production and transportation corridor, however, has come with a huge environmental price tag, one that will persist for generations, long after the hydrocarbons are depleted. Louisiana has the world’s seventh largest wetlands and produces the lion share of America’s domestic oil production. Yet Louisiana’s wetlands are disappearing and have been for sometime, along with the habitat, wildlife, culture, and traditional socio-economic activities that is unique to the region. Most of this loss has occurred between the 1950s and late 1970s, the era of intense petroleum production. The reasons for this high loss rate are complex and unique, involving a mixture of both natural and human-induced changes over time. Scientists argue that one of the major causes of this wetland loss has been the long-term direct and indirect impacts of oil-led development, namely the construction of pipeline, access, and navigation canals through the marshes, barrier islands, and bays. The energy and environmental tradeoffs have been particularly challenging given the enormous oil resources produced in the region over the decades and because of the Mississippi Delta’s complex geologic structure. Understanding how the two have interacted over time raises important questions about ecological restoration and the long-term impacts of energy production on fragile landscapes.

Unconventional remaining oil and gas resources such as tight oil, shale oil, and coalbed gas are currently the focus of the exploration and development of major oil fields all over the world. Therefore, to make best understand of target reservoirs, enhancing the vertical resolution of well log data is crucial important. However, in the face of the continuous low-level fluctuations of international oil price, large scale use of expensive high resolution well logging hardware tools has always been unaffordable and unacceptable. In another aspect, traditional well log interpolation methods can always not realize high reliable information enhancement for crucial high frequency components. In this paper, in order to improve the well log data super-resolution performance, we propose for the first time to employ Locally Linear Embedding (LLE) technique to reveal the nonlinear mapping relationship between 2-times-scale-difference well log data. Several super resolution experiments with well log data from a given area of Daqing Oil field, China, were conducted. Experimental results illustrated that the proposed LLE-based method can efficiently achieve more reliable super-resolution results than other state-of-the-art methods.
