| titleOfInvention | Composition and method of derivatives for acid stimulation of subsurface formations |
| abstract | It has been discovered that solid, particulate dicarboxylic acids are useful as derivatives in methods of acidifying subsurface formations to improve the uniformity of the acid treatments (acid displacement) by diverting acid to intervals with relatively less permeability. Particularly suitable solid, particulate dicarboxylic acids include, but are not necessarily limited to, those which are insoluble in both aqueous and hydrocarbon liquids, but which are soluble in mutual solvents or alcohol mixtures. These acids can have melting points of from about 82 to about 149 ° C, formula molecular weights of from 146 to 400, and mesh sizes from about 841 to about 38 micrometers (US standard mesh range from about 20 mesh to about 400 mesh). Specific dicarboxylic acids which fit this description include, but are not necessarily limited to, dodecanedioic acid, undecanedioic acid, decanedioic acid, azelaic acid, cork acid and mixtures thereof. |
