Stimulation / Acid Gellants

One of the most common methods of stimulating acid soluble formations is by pumping acids at greater than the formation stresses, creating a fracture. The acid etches the fracture face; creating a void in the formation when the fracture closes.

A problem in fracture acidising is loss of fluid to the formation through created wormholes. The loss of fluid to the formation decreases the effective fracture length. Increasing the viscosity of the acidising fluid reduces fluid loss by bridging the developed wormholes. The result is a longer fracture with higher conductivity.
