Install a 7-5/8 x 9-5/8 in. SET Openhole Liner (OHL) to isolate higher pressure zones so that mud weight could be reduced to combat lost circulation.
Save the wellbore by installing a SET® 7-5/8" x 9-5/8" 53.5# Openhole Liner over a 420.86 ft (128.28m) interval to isolate the weak section.
Challenge: Redevelop an established Gulf of Mexico deepwater field by accessing additional reserves.
Preserve hole size by implementing a contingency plan that included two SET® solid expandable liners and one conventional API liner run below the well’s planned 11-7/8 in. drilling liner.
Install a Solid Expandable Tubular (SET®) system to isolate the trouble zones. Retain hole size across all the depleted sands in a narrow pore pressure/fracture gradient environment....
In the Utica Shale, an Operator drilled three wells and experienced loss zones and formation integrity issues.
A major Operator in the North Sea required isolation of a high pressure gas-bearing zone to enable safe drilling and logging of the reservoir section, as well as, a solution to isolate a leaking stage tool in the 9-5/8 in. base casing.
Enhancements to standard SET technology increases the burst and collapse ratings for enhanced performance and reliability in Enventure’s High-Performance Systems.
3D seismic surveys identified deep exploratory pay interval targets below an existing field development. The Operator wanted to reach these potential pay targets by using the existing well infrastructure (by sidetracking) to drill deeper in the HPHT environment, while maintaining sufficient hole...
