METHOD AND MATERIAL FOR WELLBORE STRENGTHENING IN SUBTERRANEAN OPERATIONS

摘要

The present invention relates to methods related to plugging near-wellbore voids for wellbore strengthening. A method of wellbore strengthening may include providing a wellbore strengthening fluid comprising a drilling fluid, a particulate, and a fiber; introducing the wellbore strengthening fluid into a wellbore penetrating a subterranean formation, forming a plug comprising the particulate and the fiber in a void near the wellbore, the plug being capable of maintaining integrity at about 1000 psi (6895 kPa) or greater overbalance pressure.
