Abstract
A liquid suspension composition for wellbore operations can include a diutan gum, a viscosifier, and a carrier fluid, wherein the diutan gum is suspended in the liquid suspension composition to form a suspended diutan gum. A wellbore servicing fluid can include the liquid suspension composition, and methods of making and using the wellbore servicing fluid.
Claims24
A wellbore servicing fluid comprising:
- a liquid suspension composition for wellbore operations comprising:
- a diutan gum;
- a viscosifier;
- and
- a carrier fluid comprising brine;
- and
- a base fluid,
- wherein, prior to contacting the base fluid, the diutan gum is suspended in the liquid suspension composition to form a suspended diutan gum, which is not substantially hydrated, wherein the not substantially hydrated diutan gum has about 1.0% to about 15% weight of diutan gum per volume of brine, and
- wherein an amount of the base fluid is effective to hydrate the diutan gum to form a hydrated diutan gum, and wherein the hydrated diutan gum is present in the wellbore servicing fluid in an amount effective to suspend a particulate material.

A method of making a liquid suspension composition for wellbore operations comprising:
- contacting a diutan gum, a viscosifier, and a carrier fluid comprising brine to form the liquid suspension composition,
- wherein the diutan gum is suspended in the liquid suspension composition to form a suspended diutan gum, which is not substantially hydrated, wherein the not substantially hydrated diutan gum has about 1.0% to about 15% weight of diutan gum per volume of brine;
- and
- contacting the liquid suspension composition with a base fluid to form a wellbore servicing fluid, wherein the base fluid is present in an amount effective to hydrate the diutan gum and form a hydrated diutan gum, and wherein the hydrated diutan gum is present in the wellbore servicing fluid in an amount effective to suspend a particulate material.
1 more element
A method of performing a wellbore servicing operation, comprising:
- (a) transporting a liquid suspension composition to a location proximate to a well penetrating a subterranean formation, wherein the liquid suspension composition comprises:
- a diutan gum;
- a viscosifier;
- and
- a carrier fluid comprising brine,
- wherein the diutan gum is suspended in the liquid suspension composition to form a suspended diutan gum, which is not substantially hydrated, wherein the not substantially hydrated diutan gum has about 1.0% to about 15% weight of diutan gum per volume of brine;
- (b) contacting the liquid suspension composition with a base fluid to form a wellbore servicing fluid, wherein the base fluid is present in an amount effective to hydrate the diutan gum and form a hydrated diutan gum;
- and
- (c) placing the wellbore servicing fluid in the well.
