Abstract
A variety of systems, methods and compositions are disclosed, including, in one method, a method for well treatment may comprise providing a treatment fluid comprising an aqueous base fluid; and a nanofribril cellulose additive, wherein the nanofribril cellulose additive comprises nanofribril cellulose and a surfactant adsorbed onto a surface of the nanofribril cellulose; and introducing the treatment fluid into a well bore penetrating a subterranean formation. Additional systems, methods and compositions are also disclosed.
Claims17
A method for well treatment comprising:
- preparing a treatment fluid comprising:
- an aqueous base fluid;
- and
- a nanofibril cellulose additive, wherein the nanofibril cellulose additive comprises nanofibril cellulose and a surfactant adsorbed onto a surface of the nanofibril cellulose, wherein the nanofibril cellulose additive is a particulate with a size ranging from about 5 microns to about 1,500 microns;
- and
- introducing the treatment fluid into a well bore penetrating a subterranean formation.
A method for well treatment comprising:
- preparing a treatment fluid comprising:
- an aqueous base fluid;
- and
- a nanofibril cellulose additive, wherein the nanofibril cellulose additive comprises nanofibril cellulose and a surfactant adsorbed onto a surface of the nanofibril cellulose, wherein the nanofibril cellulose and the surfactant are present in a weight ratio ranging from about 1:5 to about 1:12, wherein the nanofibril cellulose additive is a particulate with a size ranging from about 5 microns to about 1,500 microns;
