Successful application of invisible acid completion fluid boosts Tahe Oilfield's reserves and production

Sinopec News Network reported on April 2, a new invisible acid completion fluid was successfully promoted and applied in Tahe Oilfield TKC1-1H, TK7252H and TKC1-2H wells.

Stealth acid completion fluid optimizes and transforms the reservoir through four key technologies: clay stabilization technology, acid dissolution technology, high-efficiency chelation technology, and anticorrosion and corrosion inhibition technology, which can eliminate various organic and inorganic precipitations caused by the previous working fluid.

The Northwest Oilfield is one of the oilfields with the highest well control risk of Sinopec Group.

Popularize the application of invisible acid completion fluids in Tahe Oilfield completion operations, mainly for the turbidity changes of invisible acid completion fluids at different temperatures, the pH value of invisible acid completion fluids with temperature changes, and the effects of invisible acid completion fluids.

It is understood that since 1998, invisible acid completion fluids have been widely used in many domestic oil fields, as perforation fluids, sand control filling fluids, and kill fluids and workover fluids in workover operations.
