Abstract
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.
Claims15
A method comprising:
- introducing into a subterranean formation a treatment fluid comprising a dissolvable material capable of forming a gel upon hydration, wherein the dissolvable material comprises:
- a plurality of particles;
- a plurality of flakes;
- and
- a butenediol vinyl alcohol copolymer,
- wherein the dissolvable material is configured to dissolve at or below about 150° F. and within about 8 hours, and
- wherein the dissolvable material is about 0.5 wt % to about 5.0 wt % of a total weight of the treatment fluid.
A well treatment fluid comprising:
- a dissolvable material capable of forming a gel upon hydration, wherein the dissolvable material comprises:
- a plurality of particles;
- a plurality of flakes;
- and
- a butenediol vinyl alcohol copolymer,
- wherein the dissolvable material is configured to dissolve at or below about 150° F. and within about 8 hours, and
- wherein the dissolvable material is about 0.5 wt % to about 5.0 wt % of a total weight of the well treatment fluid.
A well treatment fluid comprising:
- a dissolvable material configured to dissolve within about 8 hours, the dissolvable material comprising:
- a plurality of particles;
- a plurality of flakes;
- and
- a butenediol vinyl alcohol copolymer,
- wherein the butenediol vinyl alcohol copolymer is about 0.5 wt % to about 5.0 wt % of a total weight of the well treatment fluid.
