  • Use of an acid soluble or degradable solid particulate and an acid liberating or acid generating composite in the stimulation of a subterranean formation
    Patent number: 10662748
    Abstract: The flow of a stimulation fluid may be diverted from a high permeability zone to a low permeability portion of a subterranean formation by use of an acid soluble or acid degradable solid particulate and a composite of an acid or an acid generating compound adsorbed onto a water-insoluble adsorbent. Conductive flow of hydrocarbons from an occluded fracture may be resumed by release of the acid from the adsorbent or the acid generating compound.
    Type: Grant
