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 the Marcellus Shale, fracturing rates and pressures can be substantial, but there are other problems also associated with completing these wells, which can promote casing failure or compromise the pressureintegrity of a well. A...

A major operator in the Eagle Ford began a well recovery program to re-activate over 30 wells that stopped producing due to compromised well integrity (leaks).

An Operator, in the Ardmore Basin, was unable to put a well onto first production due to casing damage at a 5½” to 4½” casing crossover.

An Operator, in the Permian, discovered they did not obtain cement coverage along the entire length of the lateral after cementing their production casing.

A major Operator in the Marcellus required a solution to seal squeeze perforations which would have to withstand high pressure frac operations. The area Regulatory Agency had suspended operations, not allowing completion of the well due to poor cement behind the production casing. The Operator...

An Operator in the West Virginia Marcellus Shale required a cost-effective solution to seal off old perforations to enable high-pressure refrac operations.  The ESeal RF Liner was successfully installed in the horizontal wellbore and tested to 9,500 psi.

A major Operator in the Permian wanted to start its frac program on a well, but found that nearly 200 ft of the 5-1/2 in. production casing had collapsed.  The ESeal HP Liner ID was sufficient enough for the planned frac treatment to be completed ensuring a return on the $2M investment to drill...
