Degradable perforation balls and associated methods of use in subterranean applications

摘要

Methods of making a degradable ball composition comprising a carboxylic acid, a fatty alcohol, a fatty acid salt, a fatty ester, or a combination thereof comprising the steps of: forming a thermoplastic mass, and allowing the thermoplastic mass to cool as to form a degradable ball that is introduced in subterranean treatments by a carrier fluid.

主权项

1. A method of making a degradable ball composition comprising:
providing a degradable material selected from the group consisting of a carboxylic acid selected from the group consisting of: sebacic acid, stearic acid, pamoic acid, suberic acid, traumatic acid, thapsic acid, azelaic acid, camphoric acid, campholic acid, muconic acid, undecanedioic acid, brassylic acid, melissic acid, p-toluic acid, sorbic acid, dodecanedioc acid, tetradecanedioic acid, α-Aleuritic acid, and combinations thereof; melting the degradable material to form a thermoplastic mass; injecting the thermoplastic mass into a substantially spherical mold; cooling the mold to form a degradable ball; and, releasing the substantially spherical, degradable ball from the mold.
