Abstract
A method for enhancing the clean-up of a hydrocarbon-producing well, in which particles are pumped into the well to promote the recovery of the hydrocarbons. The particles are coated with a water-repellent composition to prevent, or at least minimize, the coating or adsorption of any gel polymer from the carrier fluid for the particles.
Claims86
A method comprising dry coating particles with a water-repelling composition, and pumping the particles downhole into a well to promote the recovery of hydrocarbons from the well.
A method for treating particles to make them water-repellent, comprising dissolving an oil-soluble composition in a solvent, admixing or spraying the resultant solution on the particles, and then evaporating the solvent to form a film encapsulating the particles.
A product made by coating particles with an organo-silicon compound.
A method for treating a hydrocarbon producing well comprising mixing particles in a carrier fluid comprising a water-based polymer to form a mixture, pumping the mixture downhole in a well to form a gravel pack, and coating the particles with a water repellent composition wherein the particles are coated before being mixed in the carrier fluid whereby the coating prevents absorption of the water-based polymer on the surfaces of the particles.
A method for treating a hydrocarbon producing well comprising mixing particles in a carrier fluid comprising a water-based polymer to form a mixture, pumping the mixture downhole in a well to a fracture in a formation adjacent the well to function as a proppant, and coating the particles with a water repellent composition, wherein the particles are coated before being mixed in the carrier fluid whereby the coating prevents absorption of the water-based polymer on the surfaces of the particles.
