Abstract
Methods of treating a subterranean formation including shale include preparing a treatment fluid by mixing an aqueous base fluid and a dry polyvinyl pyrrolidone (PVP) in flake or powder form having a molecular weight between about 500,000 and about 2,000,000 and introducing the treatment fluid in the subterranean formation.
