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...
