METHODS FOR INCREASING THE SURFACE AREA OF FRACTURES OR TO INCREASE THE DEPTH OF PENETRATION FRACTURES IN LOW PERMEABILITY OIL AND GAS RESERVOIRS CONTAINING SHALE TO INCREASE PRODUCTIVITY |
摘要 |
A method of treating a subterranean formation includes providing capsules comprising at least one of a mineral acid, a Lewis acid, a hydrolysable acid precursor, and mixtures thereof; providing a carrier fluid; placing the capsules and the carrier fluid into a zone in a shale formation, the zone comprising fractures; allowing the capsules to at least partially dissolve. Upon the hydrolysis of the acid, etching of the faces of the fractures occurs. |
