Abstract
A method of treating a subterranean formation comprising: forming a treatment fluid by adding a desired volume of a liquid concentrate suspension to at least a base fluid, wherein the treatment fluid comprises the liquid concentrate suspension and the base fluid, and wherein the liquid concentrate suspension comprises: (A) water; (B) an additive; and (C) a magnesium silicate clay, wherein the clay increases the viscosity of the water, wherein the liquid concentrate suspension is stable for a time period of at least 2 weeks; and introducing the treatment fluid into the subterranean formation.
Claims17
A method of treating a subterranean formation comprising:
- forming a treatment fluid by adding a desired volume of a liquid concentrate suspension to at least a base fluid, wherein the treatment fluid comprises the liquid concentrate suspension and the base fluid, and wherein the liquid concentrate suspension consists essentially of:
- (A) water;
- (B) an additive in a concentration of about 50% to about 80% by volume of the water;
- wherein if the additive comprises a hydrophobic group, the liquid concentrate suspension then additionally comprises a surfactant;
- and
- (C) an organically functionalized magnesium silicate clay, wherein the clay increases the viscosity of the liquid concentrate suspension to a viscosity of about 500 cP to about 2000 cP, wherein the clay is in a concentration in a range of about 0.2% to about 2.5% by weight of the water,
- wherein the liquid concentrate suspension is stable for a time period of at least 2 weeks;
- and
- introducing the treatment fluid into the subterranean formation.
A liquid concentrate suspension for use in a subterranean formation consisting essentially of:
- water;
- an additive in a concentration of about 50% to about 80% by volume of the water;
- wherein if the additive comprises a hydrophobic group, the liquid concentrate suspension then additionally comprises a surfactant;
- and
- an organically functionalized magnesium silicate clay, wherein the clay increases the viscosity of the liquid concentrate suspension to at least a viscosity of 500 cP, wherein the clay is in a concentration in a range of about 0.2% to about 2.5% by weight of the water, wherein the liquid concentrate suspension is stable for a time period of at least 2 weeks.
