Petro Danial Kish is proud to be among the companies at the forefront of the oil and gas industry, successfully designing and executing a selective acidizing operation using a packer in the Sepehr Field, one of the industry's challenging and complex projects. With downhole pressure exceeding 10,000 psi and temperatures above 120°C, the well presented significant challenges for inflatable packer installation due to the high presence of aromatic compounds, H₂S, and CO₂. Drawing on extensive technical expertise and field experience, our specialists developed a carefully engineered solution for the selective acidizing operation, which was successfully implemented. The success of this project not only contributed to increased production, but also demonstrated the technical capability, engineering expertise, and innovative approach of our specialists in addressing complex operational challenges.
