Effective Stimulation of Very Thick, Layered Carbonate Reservoirs Without the Use of Mechanical Isolation

Effective matrix acid stimulation is one of the keys to maximizing and maintaining long-term North Field well productivity.<br>ExxonMobil and RasGas Company Limited (RasGas) had jointly developed an integrated methodology to optimize matrix<br>stimulation for layered Khuff reservoirs, specifically for K1-K3 and K4 completions. The integrated methodology is a<br>continuous process which consists of five main elements to help overcome the well and reservoir challenges, including<br>reservoir objectives, completion strategy, stimulation design, implementation, and evaluation.
