1. A method of treating a subterranean formation penetrated by a wellbore to mitigate the production of undesirable fluid from the wellbore, the method comprising:
- producing the undesirable fluid from a zone predominantly containing the undesirable fluid so as to form a cone from a zone predominantly containing desirable fluid into the zone predominantly containing the undesirable fluid;
forming a treatment fluid comprising a carrier fluids and at least one of an oil-wetting or water-repelling surfactant;
introducing the treatment fluid into the wellbore; and
,subsequently producing from the zone predominantly containing the desirable fluid.

Abstract
A method of treating a subterranean formation penetrated by a wellbore to mitigate the production of unwanted fluids from the wellbore is carried out by forming a treatment fluid containing at least one of an oil-wetting or water-repelling surfactant and a carrier fluid. The treatment fluid is then introduced into the wellbore. The treatment or treatments may be performed remedially or prophylacticaly. The treatment may include the completion and production of zones containing the undesirable fluid(s) and the deliberate formation of cones therein.

18. A method of treating a subterranean formation penetrated by a wellbore to mitigate the production of undesirable fluid(s) from the wellbore, where a cone of the undesirable fluid exists in the zone predominantly containing the desirable fluid, the method comprising:
-
forming a treatment fluid comprising a carrier fluid and at least one of an oil-wetting or water-repelling surfactant; introducing the treatment fluid into the wellbore; and
