Abstract: This thesis describes the development of an expert system that automates the design of carbonate reservoir matrix acidizing. There are many rules and constraints that govern the design of this process. Automating these rules speeds up the decision process, and helps novice engineers to make better design, and eliminates the need to have experts around in every design job. The system provides specific acidizing treatment recipes to either remove the damage or enhance the permeability around the wellbore, and ultimately improve the well productivity. The carbonate matrix acidizing treatment starts by giving wellbore cleanout recommendations, followed by pre-flush, main acid, diversion, and post-flush recommendations The developed system in this study includes the treatment selection of the pre-flush stage, the main acid stage, diversion stage, and the post-flush stage. Also, it includes the additives that are recommended to be used in the treatment. The compatibility between the recommended acids with the additives, and the rock mineralogical composition and the crude composition, has been considered to ensure full effectiveness of the carbonate acidizing treatment Application of the developed expert system to carbonate acidizing treatment design has been illustrated using several documented case histories. The acidizing guidelines used in the system replicate the standard field procedures and practices for carbonate reservoir acidizing. Implementation of these guidelines contributes in improving the success rate of the acidizing treatment and avoiding the financial losses associated with design failures
