Differential etching in acid fracturing |
| abstract |
A method for fracturing a subterranean formation is provided in which inert masking material particles are injected into the formation with a dissolution agent so that the masking material inhibits dissolution where it contacts a portion of one or both fracture faces. The undissolved regions provide support to keep the fracture open after the treatment and the dissolved regions provide a conductive pathway for flow of fluid to or from the wellbore. |
