Abstract
The method consists in that the formation pressure is measured, and a solvent is fed through a well into the formation. Then a hydrophilizing solution is fed through the same well into the same formation. The supply of the solvent and hydrophilizing solution is effected while keeping the bottom hole pressure approximately equal to the formation pressure.
