Patent Images
1. A method for mitigating condensate banking in the vicinity of a wellbore for a gas condensate reservoir, the method comprising:
- contacting a sandstone formation in the vicinity of a wellbore for a gas condensate reservoir with a polymer solution, wherein the polymer solution comprises a charged polymer with a first net charge, thereby forming a modified sandstone formation; and
contacting the modified sandstone formation with a particle suspension, wherein the particle suspension comprises charged particles with a second net charge, wherein the first and second net charges are opposed.
