| titleOfInvention | Oil-Swellable, Surface-Treated Elastomeric Polymer and Methods of Using the Same for Controlling Losses of Non-Aqueous Wellbore Treatment Fluids to the Subterranean Formation |
| abstract | An oil-swellable lost circulation material (LCM) formed from an elastomeric polymer and a crosslinker amine is provided. The LCM may be formed from elastomeric polymer particles, a crosslinker amine, an anti-agglomerating agent, and may also be formed using a cure accelerator. A mixture of the elastomeric polymer particles, the crosslinker amine, the anti-agglomerating agent, and in some mixtures the cure accelerator, may be hot rolled at a temperature of at least 120 ° F. for a duration. The resulting LCM may swell by absorbing about 20 to about 34 times its weight when introduced to a loss circulation zone in the presence of a non-aqueous fluid such as a drilling mud or component of a drilling mud. |
