Case Study: Middle East Field Well Operating Company achieves higher production with SLB ACTive Coiled Tubing Services

ACTive Coiled Tubing Services Enable Real-Time MaxCO3 Acid Stimulation Treatment

SLB worked with Middle East Field Well Operating Company, an operator in a challenging Middle East carbonate field, to address poor well productivity caused by high temperatures, uneven zone pressures, scale buildup, and fluid loss into thief zones. The wells required effective matrix acid stimulation, but conventional hydrochloric acid treatments delivered only marginal gains, so the company needed a better way to place acid in difficult-to-reach zones.

SLB used ACTive live downhole coiled tubing together with Jet Blaster scale removal and MaxCO3 degradable diversion acid to optimize the treatment in real time. Real-time pressure and temperature data let the team monitor diversion and adjust the job as it progressed, improving acid placement and uniformity. The result was successful diversion in a well where it had previously been impossible, with higher production rates than offset wells treated with conventional matrix acid stimulation.
