Expandable-tubular technology involves a process that expands casing in oil wells drilled in especially challenging environments, such as deepwater. Until now, operators have had to use progressively smallerdiameter pipe as a well was drilled deeper; but expandable-tubular goods are designed for...

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...

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...

In the 15 years that solid expandable technology (SET) has been available, more than 1600 systems have been installed globally. This equates to enough solid expandable pipe to reach the International Space Station and beyond - over 260 miles. A growing portion of this pipe is designed for HPHT...
