Ecological and economic aspects of by-pass water deposits use in the eastern oil region of Ukraine

Abstract

Formulation of the problem. Oil deposits in the eastern region of Ukraine are confined to the upper zone of the lower hydrogeological floor (zone of stagnant regime). This zone lies at depths from 1.5 to 5.5 km, including most of the Paleozoic deposits, is characterized by the development of primary pore sandy-aleuric and cavernous-fractured carbonate reservoirs with high porosity and permeability in which broaching systems of formation, massive-reservoir and massive reservoirs are filled with sedimentogenic brines.

Most of the deposits are depleted or are being developed in the final stages, in which, along with oil, there is also by-pass water in the extracted fluid.

Factors affecting the environment during oil production are considered. The schemes of by-pass water impact on the environment are given.

Results. In the article w show the urgency of stratal water use as hydromineral materials. Bromine, iodine, lithium are the main chemical components whose content defines water as a valuable raw material. Practical use of stratal water in Ukraine will increase the mineral resource base and reduce the impact on the environment.

The authors analyze stages of the field development in terms of the extracted fluid water content. The water coefficient in produced fluid extracted on the oil field is the main element that increases the cost of oil. In the article the theory using stratal water is presented, which allows the transfer of these waters expenditure component in revenue.

The authors describe theoretically "perfect" conditions in which the oil companies developing oil fields will work with profit. There are basic parameters that influence the overall profit of the company in terms of water production formation and considers in detail the income and expense components.

Scientific novelty and practical significance. The article compares profitable work of the oil company without implementing related-field water as raw hydromineral. The authors graphically expressed how oil companies can increase their profits by using stratal water and keeping on development period. The paper determines that concentration of chemical components in water is the main indicator showing possible industrial development and building price on hydro- raw materials.
