Acidizing is part of Calfrac’s full suite of pressure-pumping services. Calfrac’s specially formulated acid blends have wide applications to repair and enhance the performance of producing oil and natural gas wellbores. Acid may be used to stimulate and improve the performance of disposal wells.
Acid is also used to stimulate well productivity in carbonate reservoirs, by dissolving portions of the reservoir rock adjacent to the wellbore. Acid jobs can be low-rate squeeze treatment or high-rate acid fracture treatment in conjunction with hydraulic fracturing that places proppant into the channels etched by the acid treatment.
