Plugging and abandoning a well using a set-delayed cement composition comprising pumice
摘要
Disclosed herein are cement compositions and methods of using set-delayed cement compositions in subterranean formations. In one embodiment a method of plugging a wellbore is described. The method comprises providing a set-delayed cement composition comprising pumice, hydrated lime, a cement set retarder, and water; activating the set-delayed cement composition to produce an activated set-delayed cement composition; introducing the activated set-delayed cement composition into the wellbore; and allowing the activated set-delayed cement composition to form a plug in the wellbore that has a permeability of less than 0.1 millidarcy.
