This paper presents an expert system-based tool used in the matrix treatment area to determine the sequence of fluids to pump. The reasoning is performed in two steps and is based on chemical rules. Multiple solutions which are ranked are provided, along with dynamic explanations. Corresponding generic chemical descriptions and proprietary products occurs in the final mapping phase, which also ensures product compatibility.

The software has been tested by compassing the conformity of the predicted sequence of fluids against actual expert designs.
