ABSTRACT:
A water-producing zone in a reservoir penetrated by a gravel-packed well is isolated by placing a bridge plug in the well tubing adjacent to the top of the water-producing zone, then placing a first coarse sand on the bridge plug, followed by a fine sand on top of the coarse sand, and finally by placing a flowable resin on top of the fine sand where it spreads out through the gravel pack to provide a flow barrier to water.
