Patent application title: Water Swelling Rubber Compound
[0021]A new water-swelling rubber compound has been discovered that gives improved water swelling volumes under the same conditions as compared with conventional compounds. Through the combination of at least two polymer families, as well as the optimization of other components, a rubber compound has been developed for use in downhole applications that will swell in water-based fluids such as water based muds or brines to an improved extent.
