Abstract
A method of treating a subterranean formation penetrated by a wellbore utilizing a preformed high solids content slurry is prepared and transported to the wellsite. A portion of the slurry is admixed with a treatment fluid whereby the resultant solids content of the fluid is reduced and the fluid is introduced into a wellbore penetrating the subterranean formation. The high solids content slurry is substantially stable and the particulate does not substantially settle within the fluid prior to admixing with the treatment fluid thereby permitting large quantities of particulate to be rapidly admixed with a treatment fluid.

A Method for forming a particulate containing treatment fluid for introduction into a subterranean formation comprising:
- preparing a treatment fluid containing a gelling agent;
- preparing a particulate slurry by admixing a particulate with a gelled aqueous fluid of certain visco-elastic properties such that said particulate is present in an amount of at least about 23 pounds per gallon of fluid;
- intermixing streams of said treatment fluid with said particulate slurry to form a particulate containing treatment fluid;
- and introducing the particulate containing treatment fluid stream into a wellbore penetrating a subterranean formation.
A method for treating a subterranean formation penetrated by a wellbore comprising:
- preparing a treatment fluid containing a gelling agent to viscosity the fluid;
- preparing a particulate slurry by admixing a particulate with a gelled aqueous fluid wherein said particulate is substantially non-settling in said gelled aqueous fluid and said particulate is present in an amount of at least about 23 pounds per gallon of fluid;
- pumping a stream of said treatment fluid at an elevated pressure and pumping a stream of said particulate slurry at an elevated pressure and admixing said streams whereby a particulate containing treatment fluid is formed;
- and
- introducing the particulate containing treatment fluid into a wellbore penetrating a subterranean formation.
