摘要： Methods of using water-soluble hydrophobically modified polymers to treat intervals of a subterranean formation having variable permeabilities. An exemplary embodiment provides a method of treating an interval of a subterranean formation having a permeability that varies. The method comprises contacting the interval with a water-soluble hydrophobically modified polymer capable of selectively reducing the effective permeability of the interval to water without a comparable reduction of the effective permeability of the interval to hydrocarbons. The hydrophobically modified polymer modifies the interval to have a more uniform permeability without substantially preventing the flow of fluids through the interval. The method further comprises introducing a treatment fluid into the interval. The more uniform permeability of the interval allows for a more uniform treatment of the interval by the treatment fluid than would be allowed without treatment of the interval with the hydrophobically modified polymer.

摘要： The present invention provides a method of controlling fluid loss to a permeable formation penetrated by a wellbore. A novel fluid loss agent is prepared by forming a crosslinked polymer gel which then is sheared to break the gel into discrete particles of a particular size range. A slurry then is formed of the particles by dispersing the particles in an aqueous fluid having a density similar to that of the gel particles. The slurry then is introduced into contact with the permeable formation and a filter cake of the particles is formed upon contact with the formation and loss of the slurrying fluid to the formation. The filter cake provides further fluid loss control to the permeable formation.
