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.
