titleOfInvention | LOW-TOXIC STAGGER AND METHODS OF ITS APPLICATION |
abstract | Reduced toxicity thickening compositions are used in treatment fluids in underground operations; The methods include preparing such treatment fluids containing a thickening composition and a water based solution, the thickening composition containing hydroxyethyl cellulose from about 10 to about 60% by weight of 2-pyrrolidone and from about 10 to about 60% by weight of a water-soluble propylene glycol monoalkyl ether, essentially no effect of swelling on hydroxyethyl cellulose, the mass ratio of hydroxyethyl cellulose to 2-pyrrolidone is from about 1: 2 to about 2.6: 1, and the method involves placing the treatment fluid into the subterranean formation. |
