| titleOfInvention | Methods for improving coatings on downhole tools |
| abstract | The present invention relates to the use of degradable coatings suitable for use on downhole tools. In particular, the present invention relates to pliable coatings for use on downhole tools that have been designed to be able to resist flaking or breaking off of the tool in response to a physical shock. Some embodiments of the present invention provide methods of reacting lactic acid, glycolic acid, or a combination thereof in a polymerization reaction to form a degradable polymer; combining the degradable polymer and a plasticizer to form a coating composition; applying the coating composition to a downhole tool; placing the coated downhole tool into a portion of a subterranean formation; and, hydrolyzing the degradable polymer of the coating composition to release an acid and degrade the coating. |
