ABSTRACT:
A method of protecting a permeable formation penetrated by a well bore against damage by subsequent treatment operations. In protecting the formation against damage by cement used in installing a casing, a well bore is drilled through the formation and liquid composition capable of gelling is introduced into the area of the formation. After the gel is formed it is drilled out, leaving a sufficient amount still plugging the voids in the formation wall. Subsequently, after installing the casing, the gel reverts to liquid form, leaving the permeable formation in condition for production of the well. Preferably, the gel contains a breaker to cause the gel to revert to liquid form after a predetermined period of time.
