A Small-Scale Fracture-Conductivity Study

A series of acid-fracture-conductivity tests was conducted that simulated flow in a hydraulic fracture, both in the main flow direction along the fracture and in the fluid-loss direction. Three commonly used acid-fracturing fluids were tested at 200 and 275°F. The acid-fracture-conductivity apparatus is similar to a standard American Petroleum Institute (API) fracture-conductivity cell, but with the ability to hold core samples that are 3 in. thick in the leakoff direction.
