Acid Stimulation in Deep Wells: Addressing Productivity Challenges

STIMPRO Case Study

Acid stimulation is a proven technique to enhance well productivity, but its effectiveness can be short-lived, especially in deep, formations like the Gulf of Mexico (GOM). In one GOM well, after frac-packing and two rounds of acid stimulations, performance improved initially, but the Productivity Index (PI) dropped from 2.10 Bbls/psi to 0.6 Bbls/psi. This decline left operators searching for answers: what went wrong, and how could they improve the long-term performance of the well?
