Permeability control for enhanced oil and gas recovery in unconventional reservoirs using advanced mineral precipitation technologies

Unconventional oil and gas recovery has succeeded because of the ability to increase permeability in tight source rock via fracturing- While this has led to large increases in resource recovery, the ability to modify fracture apertures to allow finer control of permeability in these rocks has the potential to increase recovery efficiency- This SBIR project focuses on developing and commercializing advanced mineral precipitation technology capable of modifying and controlling permeability in subsurface porous media (including proppant) and in fractures in tight shale formations- The advanced mineralization sealing methods are aimed at developing low viscosity fluid-based mineral precipitation sealing technologies which address a wide range of subsurface temperature (and depth) conditions to increase resource recovery efficiency-
