Abstract
Chemical treatment agents are supplied to a well or borehole extending through an earth formation by subjecting the well to a fracturing treatment with a high pressure fluid and proppant particles. The proppant particles are thereby trapped in fractures in the earth formation. Some or all of the proppant particles are of porous insoluble inorganic material, and are impregnated with a chemical treatment agent, such as a scale inhibitor or a corrosion inhibitor. The porous particles may be of a ceramic or oxide material, for example a silica and/or an alumina-based material.
