03/13/2012
An operator drilling a sub-salt exploration deepwater well in Gulf of Mexico, experienced an unstable wellbore at the base of the salt; which resulted in setting the 9-7/8 in. liner 3,400 ft higher than originally planned.
In exploratory wells, maintaining hole size is critical due...

The Operator had two sections of perforations in 4-1/2 in. casing that needed to be repaired. They required a solution that would repair the 4-1/2 in. casing and still maintain sufficient ID for this well to be used as a power water injector well.

Within a tight timeframe, identify, develop and execute the ~60 load cases defined as necessary and relevant for gas-tight qualification and to ensure fluid compatibility with the elastomers. Accurately place the system, with only a two-meter margin for error and expand the SET liner to...

As part of a multi-well program, isolate severe water-thief zones in a field where squeezing, casing patches and dual packer isolation assemblies rarely worked. The solution increased production and ultimately resulted in higher reserves.

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.

09/19/2006

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.

07/14/2005

Remove recovery obstacles in openhole laterals by combining SET® solid expandable systems with intelligent well technology.

03/03/2005

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.

03/26/2007

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....
