Economic Evaluation and Estimation

This chapter outlines a method for cost-effective evaluation and estimation of matrix acidizing projects. It details the essential expenses involved, such as acid, additives, equipment, and labor, and elucidates on how to compute them based on factors like acid type, concentration, injection rate, and volume. Moreover, it delves into estimating flow rate changes post-acidizing, considering reservoir characteristics, acid-rock interactions, and stimulation efficiency. The discussion extends to estimating costs and profits resulting from acidizing, employing net present value (NPV) as a key metric. Additionally, the chapter introduces the concept of the fold of increase (FOI), a measure of the incremental profit-to-acidizing cost ratio, and elaborates on maximizing it through well-informed decisions. Ultimately, the chapter endeavors to offer a practical and valuable tool for the economic analysis and optimization of matrix acidizing projects.
