PROCEDURES AND COMPOSITIONS FOR COMPLETION OF WELL AT OUTBREAK OF WELLS WITH STEAM Russian patent published in 2011 - IPC E21B43/24 

Abstract RU 2435946 C2

FIELD: gas and oil production.

SUBSTANCE: washing fluid containing common oil dissolver is injected into near well bore zone of at least part of well borehole. Also, water washing fluid is injected into the near well bore zone. Water fluid contains surface active substance - SAS- facilitating wetting silicon oxide with oil. Further, into the near well bore zone there is injected processing solution containing hardened resin. While being injected, hardened resin is in a non-solidified state. Upon solidification hardened resin is stable at least to 350°F (177°C). To outbreak the zone near well bore there is injected steam.

EFFECT: raised efficiency of stabilisation of near well bore zone and recovery of hydrocarbons.
