Prospects of applying formation water and heavy brines derived therefrom in oil production and national economy

Abstract

In recent years, the amount of minerals recovered from the earth interior exceeds their production over the entire past human history. The reserves of some rare elements have been significantly reduced and the demand for them has increased dramatically through the use of new techniques and technologies. The task of developing new types of mineral raw materials from formation waters has become ever more relevant. In the process of formation water preparation during the production of table salt the fluids and heavy brines are obtained, which are suitable for their further use in oil production. The fluid obtained through deferrization of formation water has reduced content of magnesium ions. The use of this fluid makes it possible to increase the mechanical strength of the cement stone, the tightness of the “column-cement stone” contact zone, and to reduce magnesia corrosion.

Prospects for the use of advanced computer modeling systems in planning geological and technical activities

“…About 15-20 years ago, the lion's share of capital works at wells was occupied by physico-chemical, mechanical and thermal effects on the bottom-hole zone of the formation, the introduction of installations for simultaneous separate operation, simultaneous separate injection, drilling of lateral and horizontal shafts in order to involve previously undrained oil and gas reserves. This was due to the need to build up the potential of deposits ahead of time relative to the development periods and to some extent was a prerequisite for even more intensive wear of downhole equipment [5][6][7][8].…”

Comparison of the effectiveness of flow diverting technologies with hydrodynamic oil recovery improvement methods

“…The efficiency of oil reserves development sharply decreases, although the recovery from the initial recoverable reserves does not exceed 40-50%. Most of the geological reserves remain outside the development system [1][2][3][4]. To change the current state and improve the efficiency of the existing development system, flow diverting technologies (FDT) can limit the filtration of injected water through the flooded areas of the reservoir and direct it to undeveloped oil-saturated zones.…”

Technical and technological justification of repair and insulation works at oil fields of the Republic of Tatarstan using special compositions

“…It is known that the efficiency of oil field development is largely defined by the state of production and injection well stock, which determines the continuity of their operation and high technical and economic indicators [1][2][3][4][5].…”
