On reasons for the deterioration of the bottomhole formation zone and recommendations for maintaining reservoir properties

Abstract

Abstract The literature on the deterioration of reservoir properties of the bottomhole zone during various operations in the wells and when acting on the reservoir is reviewed. It was revealed that bullhead well control operations and impacts on the bottom-hole formation zone have a very large negative impact if the current geological and physical conditions of the object are not taken into account. Laboratory and field tests of several hydrocarbon-based emulsion formulations were performed. Experiments and tests have shown the effectiveness of the proposed formulations and allow recommend them for use in well repair.
