The processes of produced water control in oil-gas industry lead to the periodical environmental improvement. Proceeding intensive oil development in Absheron peninsula throughtout over 150 years led to the increase of flooding percentage and oil decrease in geological reservoir. Therefore, due to the fact that the capacity of produced water together with oil exceeds for several times the total capacity of extracted oil, the issues associated with the further recycling and systematic control on produced water are particularly topical. The implementation of fully closed system of produced water control formed in the oil and gas development in Absheron territory is considered the need of the hour. It is necessary to study the current ecological situation in oil-gas fields, increase the production efficiency and reduce the impact on environment, offering more improved methods based on up-to-date scientific and methodological analysis. The reduction of produced water capacity and gradual environmental improvement may be achieved due to the decrease of operation of highly flooded wells in the old oil-gas fields. Due to the produced water deposition from the oil in the sedimentary rocks and scavenger wells, the amount of oil in the water reduced for several times, and in this case it is possible to reduce the effect of hydrocarbons on the soil, water and atmosphere.

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.

Geopolitical Risks

The article is devoted to the consideration of geopolitical challenges for the analysis of geoenvironmental risks (GERs) in the hydrocarbon development of the Arctic territory. Geopolitical risks (GPRs), like GERs, can be transformed into opposite external environment factors of oil and gas industry facilities in the form of additional opportunities or threats, which the authors identify in detail for each type of risk. This is necessary for further development of methodological base of expert methods for GER management in the context of the implementational proposed two-stage model of the GER analysis taking to account GPR for the improvement of effectiveness making decisions to ensure optimal operation of the facility oil and gas industry and minimize the impact on the environment in the geopolitical conditions of the Arctic.The authors declare no conflict of interest

The main sources of soil pollution due to the development of oil and gas fields are analyzed. It is shown that the main sources of oil products entering the soil are sludge accumulators and drilling barns. A new construction of a drilling barn and a scheme of reclamation of the existing ones are proposed. The implementation of such developments will minimize the ingress of oil-containing fluids into the soil and increase the level of environmental safety of oil and gas development processes.

Abstract Ineffective methods of increasing oil recovery have been one of the challenges, whose solutions are constantly sought after in the oil and gas industry as the number of under-produced reservoirs increases daily. Water injection is the most extended technology to increase oil recovery, although excessive water production can pose huge damage ranging from the loss of the well to an increase in cost and capital investment requirement of surface facilities to handle the produced water. To mitigate these challenges and encourage the utilization of local contents, locally produced polymers were used in polymer flooding as an Enhanced Oil Recovery approach to increase the viscosity of the injected fluids for better profile control and reduce cost when compared with foreign polymers as floppan. Hence this experimental research was geared towards increasing the efficiency of oil displacement in sandstone reservoirs using locally sourced polymers in Nigeria and also compared the various polymers for optimum efficiency. Starch, Ewedu, and Gum Arabic were used in flooding an already obtained core samples and comparative analysis of this shows that starch yielded the highest recovery due to higher viscosity value as compared to Ewedu with the lowest mobility ratio to Gum Arabic. Finally, the concentration of Starch or Gum Arabic should be increased for optimum recovery.

The present economic model is intended to provide an example of how to take into consideration risks and uncertainties in the case of a field that is developed with water injection. The risks and uncertainties are related, on one hand to field operations (drilling time, delays due to drilling problems, rig failures and materials supply, electric submersible pump [ESP] installations failures with the consequences of losing the well), and on the other hand, the second set of uncertainties are related to costs (operational expenditures-OPEX and capital expenditures-CAPEX, daily drilling rig costs), prices (oil, gas, separation, and water injection preparation), production profiles, and discount factor. All the calculations are probabilistic. The authors are intending to provide a comprehensive solution for assessing the business performance of an oil field development.
