Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A degradable article constructed of a high strength material comprising: an aluminum-based alloy matrix containing gallium; and a plurality of carbon particles and a plurality of salt particles homogeneously distributed within the aluminum-based alloy matrix, wherein the concentration of gallium in the degradable article is highest at the outermost surface of the degradable article and the article is galvanically corrodible. 2. The…
