摘要： A wellbore treatment fluid is disclosed herein, the fluid comprising a butenediol vinyl alcohol copolymer. Also, a wellbore treatment fluid comprises a dissolvable material capable of forming a gel upon hydration, the dissolvable material having a cylindrical cross-sectional shape. Methods of treating a subterranean formation includes introducing a treatment fluid comprising a butenediol vinyl alcohol copolymer, and creating a plug with the treatment fluid.

摘要： Methods of treating formation damage or other service induced damage in a near wellbore region of a wellbore of a subterranean formation, by treating a zone or zones in the near wellbore region, and diverting treatment fluid stages from the treated zones to untreated zone(s) with an acid precursor material and optionally also with fibers. The acid precursor material has an average particle size less than 1000 microns.
