Abstract
Official abstract text for this publication.
A method begins with the step of preparing a drag-reducing additive by mixing a dispersion polymer with a surfactant and a solvent. The method continues with the step of forming a drag-reducing composition by combining the drag-reducing additive with an aqueous treatment fluid. The method further involves the step of injecting the drag-reducing composition into a subterranean formation, a pipeline or a gathering line.
First claim
Opening claim text (preview).
It is claimed: 1 . A method comprising the steps of: preparing a drag-reducing additive by mixing a dispersion polymer with a surfactant and a solvent; forming a drag-reducing composition by combining the drag-reducing additive with an aqueous treatment fluid; and injecting the drag-reducing composition into a subterranean formation, a pipeline or a gathering line. 2 . The method of claim 1 , wherein the step of forming the drag-reducing composition with the aqueous treatment fluid further comprises the step of adding the drag-reducing additive into the aqueous treatment fluid on-the-fly as the aqueous treatment fluid is pumped into the subterranean formation, the pipeline or the gathering line. 3 . The method of claim 1 , wherein the step of forming the drag-reducing composition further comprises the step of adding the drag-reducing additive to the aqueous treatment fluid before the drag-reducing composition is pumped into the subterranean formation, the pipeline or the gathering line. 4 . The method of claim 1 , wherein the step of forming the drag-reducing composition further comprises adding from about 0.01 gallons to about 50 gallons of drag-reducing additive per 1,000 gallons of the aqueous treatment fluid. 5 . The method of claim 1 , wherein the step of preparing the drag-reducing additive further comprises mixing 40-85% by weight of the dispersion polymer with 10-35% by weight of the surfactant with an HLB greater than about 8 and 5-30% by weight of the solvent. 6 . The method of claim 1 , wherein the aqueous treatment fluid comprises an acid. 7 . A method comprising the steps of: preparing a drag-reducing additive by mixing 40-85% by weight of a dispersion polymer with 10-35% by weight of a surfactant with an HLB greater than about 8 and 5-30% by weight of a solvent; forming a drag-reducing composition by combining the drag-reducing additive with an aqueous treatment fluid; and injecting the drag-reducing composition into a subterranean formation, a pipeline or a gathering line. 8 . The method of claim 7 , wherein the step of forming the drag-reducing composition with the aqueous treatment fluid further comprises the step of adding the drag-reducing additive into the aqueous treatment fluid on-the-fly as the aqueous treatment fluid is pumped into the subterranean formation, the pipeline or the gathering line. 9 . The method of claim 7 , wherein the step of forming the drag-reducing composition further comprises the step of adding the drag-reducing additive to the aqueous treatment fluid before the drag-reducing composition is pumped into the subterranean formation, the pipeline or the gathering line. 10 . The method of claim 7 , wherein the step of forming the drag-reducing composition further comprises adding from about 0.01 gallons to about 50 gallons of drag-reducing additive per 1,000 gallons of the aqueous treatment fluid. 11 . The method of claim 7 , wherein the aqueous treatment fluid comprises an acid.
