Investigations of subsurface mineral precipitation reactions associated with brine injection
Brines are injected into the subsurface every day for a variety of reasons including enhanced oil recovery, hydraulic fracturing, carbon sequestration, and wastewater disposal. Mixing of these injected brines with brines in injection formations in the subsurface can drive mineral precipitation, which can alter the porosity and permeability of the injection formation, and thus the ability to continue to inject fluid into or pump fluid out of the formation. The potential of mineral precipitation to damage a formation, makes the understanding of brine interaction in the subsurface incredibly important ...
