Description
This presentation will provide information on commonly used frac fluid systems and requirements for conducting successful fracturing treatments in the Eagle Ford Shale. Included in the discussion will be an overview of friction reduced—“slickwater”—fluids, linear gels, and cross-linked frac fluid systems; guidelines on generating proper frac fluids; and the application of common breakers. Background information on commonly used frac fluid recipes and additives, such as pH buffers, biocides, scale inhibitors, instant/delayed cross-linkers, surfactants, and common clay control products will be presented. Additionally, accepted “best” practices and field-level troubleshooting of frac fluids will be covered, with examples of “good” and “not-so-good” fluids drawn from case histories.
