Integrated approach for development of acid treatment designs for wells of R. Trebs oilfield is considered. Optimal acid blends were selected for the target high temperature carbonate reservoirs. Based on the wormhole growth model the acid treatment model was developed. The model was calibrated and adapted for the given field conditions using results of core flow tests.
