Mitigate shale formations, in which loss of returns and sticking are common, by combining SET® expandable tubulars with sidetracking operations in order to reach additional reserves with optimized hole size.
Drill through 200 feet of depleted sands, add a casing point and reach the pay target (measured depth between 11,000 to 13,000 feet) with adequate hole size while maintaining the smallest upper wellbore possible.
Optimize project economics, well design and drilling efficiency with application of SET solid expandable technology.
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.
In 2009, a global super-major operating out of Borneo experienced problems with a well it was running from a drillship in over 5,000 feet of water off of the Sarawakan coast. An initial exploration well working a straight hole in a shale formation, the operator encountered an unstable...
A major operator was sidetracking out of an existing well to a nearby reservoir.The first attempt to sidetrack utilizing a conventional casing design failed to reach the target depth and damaged the 13-3/8 in. casing.
The casing design for a...
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.

The challenge was to set three multilateral windows at an optimum Total Vertical Depth (TVD) in the reservior.
