Install a 13-3/8 x 16 in. 97.0 lb/ft openhole solid expandable tubular (SET®) system to extend the 16 in. casing section past the trouble zone—preserving the set point for the following 13-3/8 in. standard casing and enabling successful execution of the well plan.
Leverage information gained from the first well in the development project and install Solid Expandable Tubular (SET®) systems to the subsequent wells to save casing points and preserve hole size while drilling through shale formations and depleted zones.
Remove recovery obstacles in openhole laterals by combining SET® solid expandable systems with intelligent well technology.
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.
Isolate a low fracture-gradient zone to enable an optimal completion.
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....
BP experienced losses while drilling a development well due to weak sand formation directly below the 13-3/8in. shoe. Multiple attempts were made to stem the losses - all without success.
A solution was required to isolate the weak sand formation and enable drilling to continue with higher...
Offshore Denmark, Directional Well, 8 5/8 x 10 3/4
The challenge was to set three multilateral windows at an optimum Total Vertical Depth (TVD) in the reservior.
A large independent Operator discovered several leaks and a parted section in the 7 in. production casing from 2,000 ft. to 500 ft. In order to fracture the well, casing integrity had to be restored to handle over 6,000 psi surface fracture pressure to ensure the well could become a viable asset...
