This document summarizes a summer internship project evaluating the consistency of a column flow test (CFT) used to measure surfactant effectiveness in fracturing fluids. The intern found that using a massager to mix the sediment column introduced inconsistencies, with voids forming and breakthrough times varying between tests. Removing the massager improved consistency, with displacement rate proving the most consistent metric. The intern concluded the CFT's utility could be enhanced by integrating it with another test accounting for geologic composition and surfactant type.
