COMPOSITION IN PARTICULATE FORM COMPRISING A POLYMER AND A PROPPANT USEFUL FOR HYDRAULIC FRACTURING OPERATION

摘要

Composition for fracturing operation comprising at least one water-soluble or water swellable polymer and at least one proppant wherein the composition is a free-flowable powder in particulate form combining the proppant and the polymer both is in a particulate form, said particulates of water-soluble polymer before they are solubilized or particulates of water swellable polymer before they are swelled and having an average particle size comprised between 10 and 1000 microns. Hydraulic fracturing process using said composition.
