ABSTRACT:
A method of preventing intrusion of fluid into a horizontal well bore. A quantity of liquid composition capable of gelling and containing a breaker is introduced into a horizontal well bore up to a point corresponding to the bottom of the intrusion zone. After the liquid composition gels into a temporary gel, a second liquid composition capable of gelling into a permanent gel is introduced into the zone to shut off fluid flow from the zone. The temporary gel prevents flow of the permanent gel into the horizontal well bore. Thereafter the breaker in the temporary gel causes the gel to revert to a liquid, which is removed from the horizontal well bore upon production of the well.
