Wormholes Models for the Optimum Matrix Acidizing in Mi4 Unit-Ahdeb Oil Field

Innovative laboratory research and fluid breakthroughs have improved carbonate matrix stimulation technology in the recent decade. Since oil gas wells are stimulated often to increase output maximum recovery, this has resulted acidizing is a less costly alternative hydraulic fracturing; therefore, it widely employed because of its low cost fact that may restore damaged their previous productivity give extra production capacity. Limestone Mishrif reservoir never been investigated; hence revealed fresh insights into process. Many reports stated Ahdeb field's unable be due high injection pressures, which make difficult inject acid formation; (ii) only few jobs successful wells, while bulk others unsuccessful. Based on an efficiency curve, ideal gel (HCl 15%) rate for was 2.16 cc/min. This produces optimal wormhole least amount utilized. The optimum pore volume breakthrough propagation 2.73, interstitial velocity 0.6 cm/min. Researchers developed new formulae compute skin factor anisotropic carbonates generated from first time. experiment need acidify at rate.
