Abstract
The disclosure relates to the oil and gas industry, in particular, to a composite proppant modified by a polymeric carrier for the purpose of improving transport properties and delayed release of inhibitors from proppant. A composite proppant is provided which comprises at least one solid particle attached to at least one polymeric carrier facilitating a decrease in the composite proppant settling rate, where the polymeric carrier comprises inclusions of at least one inhibitor for inorganic or organic scales. The disclosure also relates to a method for manufacturing of such composite proppant and methods for using the same during hydraulic fracturing of a subterranean formation, and for treatment of organic fossils during downhole production after hydraulic fracturing of subterranean formation.
