METHOD OF USING DIVERTER AND PROPPANT MIXTURE

摘要

The flow of well treatment fluids may be diverted from a high permeability zone to a low permeability zone within a fracture network within a subterranean formation by use of a mixture comprising a dissolvable diverter and a proppant. At least a portion of the high permeability zone is propped open with the proppant of the mixture and at least a portion of the high permeability zone is blocked with the diverter. A fluid is then pumped into the subterranean formation and into a lower permeability zone of the formation farther from the wellbore. The diverter in the high permeability zones may then be dissolved at in-situ reservoir conditions and hydrocarbons produced from the high permeability propped zones of the fracture network. The mixture has particular applicability in the enhancement of production or hydrocarbons from high permeability zones in a fracture network located near the wellbore.

主权项

1. A method of stimulating the production of hydrocarbons from a subterranean formation penetrated by a wellbore, the method comprising:
(a) flowing into a high permeability zone of a fracture within a subterranean formation near the wellbore a mixture comprising a dissolvable diverter and a proppant; (b) propping open at least a portion of the high permeability zone with the proppant of the mixture and blocking at least a portion of the high permeability zone with the diverter; (c) pumping a fluid into the subterranean formation and into a lower permeability zone of the formation farther from the wellbore; (d) dissolving the diverter blocking at least a portion of the high permeability zone near the wellbore; and (e) producing hydrocarbons from the high permeability zone and the lower permeability zone.
