Enhanced oil recovery from productive formations is a primary innovative goal faced by oil producers. It can be reached only by implementing new modern techniques and technologies.
1. SP Technology
Due to temporary well plugging by linked polymers and viscoelastic systems (SP) of the most permeable productive layers of the section, there occur a drop in water consumption by washed high-permeability layers with anomalously high rate of reserve recovery, reduction of liquid rate and increase of pressure draw down in producing wells.
As a result of pressure differential increase between injection and recovery zones, reverse in place filtration flows direction, the active reserve recovery process involves oil saturated sublayers of low permeability and water content, not or partially covered by water flood before.
It results in wider producing layers coverage and oil production increase.
