DEGRADABLE BALL SEALER

摘要

High strength, degradable ball sealer for temporarily sealing off lower zones in a wellbore from the flow of a fluid injected into the well. The degradable ball sealer may also seal openings formed through slidable packers or sleeves received within a tubing string in the well, from the flow of a fluid injected into the well. The ball sealer includes an aluminum-based alloy matrix containing gallium, with graphitic carbon particulate and salt particulate homogeneously distributed within the aluminum-based alloy matrix.
