Leaking DV tool repair – Permian Basin, USA
During the first fracturing stage, a leak was discovered in the DV tool. A Saltel Patch successfully covered the DV tool at 2,000m [6,500 ft] depth and restored well integrity, enabling continued fracturing operations.
The DV tool developped a leak while fracturing the first stage, in a plug & perf horizontal well.
A 26-ft, 5.5-in extra-reinforced patch was selected. The patch was set in just over 3 hours, fully drifted at 4.25in, and pressure tested at 8,500 psi.
The fracturing operations resumed and the remaining 33 stages of the well were successfully fractured at 8,500 psi with an 80 bbl/min flow rate.
