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.
As the oil and gas industry has matured, three broadreaching and long-standing issues that affect virtually every well have assumed heightened importance: conservation of hole size, hydraulic isolation of selected zones, and maximization of well life. All of these issues involve one of the...
- Operator was experiencing trouble formation caused by narrow pore pressure/fracture gradient window which caused casing to be set higher than planned.
- Operator decided that expandables were the way to go.
- All of the customer's operating objectives were met.
By ensuring optimal hole size, well designs using solid expandable tubulars have a far-reaching effect on drilling, evaluation, completion and life-of-well solutions. Enventure Global Technology's Kevin Waddell, Jerry Fritsch and Kristaq Mitrushi discuss the growing influence of solid...
An major operator received one of the first post-Macondo permits to continue drilling an exploratory well in the deepwater Gulf of Mexico using subsea BOP's.
The operator needed to achieve zonal isolation across shallow hydrocarbon-bearing sands and to reduce ECD's during cementing...
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.
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.
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...
