Abstract
Additives are used in treatment fluids in subterranean operations to prevent fluid loss within a subterranean formation. A method includes providing a treatment fluid that includes a viscosifying polymer and a solid-liquid phase transition temperature modifier and placing the treatment fluid in a subterranean formation penetrated by a wellbore, wherein the solid-liquid phase temperature modifier is added in an amount to modulate the gelling temperature of the viscosifying polymer to a target temperature.
Claims25
A method comprising:
- providing a treatment fluid comprising a viscosifying polymer and a solid-liquid phase transition temperature modifier;
- and
- placing the treatment fluid in a subterranean formation penetrated by a wellbore
- wherein the solid-liquid phase transition temperature modifier is added in an amount to modulate the gelling temperature of the viscosifying polymer to a target temperature.
A method comprising:
- providing a treatment fluid comprising a glycerine carbonate-modified water soluble cellulose ether;
- and
- placing the treatment fluid in a subterranean formation penetrated by a wellbore.
A method comprising:
- providing a treatment fluid comprising a glycerine carbonate-modified water soluble cellulose ether and a surfactant;
- and
- placing the treatment fluid in a subterranean formation penetrated by a wellbore.
A method comprising:
- providing a treatment fluid comprising an organic carbonate-modified water soluble cellulose ether and a surfactant;
- and
- placing the treatment fluid in a subterranean formation penetrated by a wellbore to provide fluid loss control.
A method comprising:
- providing a treatment fluid comprising an organic carbonate-modified water soluble cellulose ether and a surfactant or a non-surface active organic salt;
- and
- placing the treatment fluid in a subterranean formation penetrated by a wellbore to reduce water influx into the wellbore.
A method comprising:
- providing a first treatment fluid comprising an organic carbonate-modified water soluble cellulose ether and a surfactant or a non-surface active organic salt;
- placing the first treatment fluid in a first portion of a subterranean formation penetrated by a wellbore;
- and
- placing a second treatment fluid in the wellbore, wherein the second treatment fluid is diverted away from the first portion of the subterranean formation.
