Abstract

An increasing trend in the oil production decline rate observed over the last few years poses risks of failure to meet production targets and to achieve planned oil recovery efficiency in many hydrocarbon fields. Under current conditions, use of physical-and-chemical EOR methods, particularly, flow diverting agents, is of utmost importance. Domestic experience shows that the most efficient among such EOR methods are conformance control in injection wells and flow diverting technologies using various disperse systems.
The paper studies the applicability of a water-repellent filling agent in disperse systems. The authors present the advantages of using this agent compared to the currently applied industrial fillers, such as mud powder and wood flour.

Key words:

sedimentary and aggregate stability, high-dispersive filling agent, polyacrylamide, mud powder, system stability, residual resistance coefficient, oil displacement
