Abstract: Process of fracturing subterranean, oil- and/or gas-bearing formations by injecting an aqueous fracturing fluid into a wellbore at a rate and pressure sufficient to penetrate into the formation, and to initiate or extend fractures in the formation, wherein the aqueous fracturing fluid is obtained by mixing at least an aqueous base fluid and an aqueous polyacrylamide concentrate having a concentration of 3.1 to 14.9% by weight of polyacrylamides, relating to the total of all components of the aqueous polyacrylamide concentrate, and wherein at least a part of the aqueous fracturing fluid injected additionally comprises a proppant.

CPC classification number: C08L33/26 , C09K8/588 , E21B43/162
Abstract: Process of providing polyacrylamides to a site-of-use comprising at least the steps of mixing a polyacrylamide powder at a manufacturing site with an aqueous liquid, thereby obtaining a homogeneous aqueous polyacrylamide concentrate, transporting said concentrate in a transport unit from the manufacturing site to the site-of-use, and removing the homogeneous aqueous concentrate from the transport unit at the site-of-use. Process of treating subterranean, oil and/or gas bearing formations by injecting an aqueous treatment fluid into at least one wellbore, wherein the aqueous treatment fluid is manufactured by mixing at least an aqueous base fluid with said homogeneous aqueous polyacrylamide concentrate at the site-of-use.
