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...

Implement an ESeal solution that would enable targeted completion with packer seats while also repairing the damaged vertical section of casing in the Barnett.

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...

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.

An Operator needed to isolate a damaged interval in the existing 5-1/2 in. casing, when two previous patches attempts failed pressure testing.

A Major Mid-Continent Operator needed a solution that could cover four perforations that were prematurely shot in the heel of the horizontal Woodford Shale well.  The ESeal HP Liner was successfully tested to 13,500 psi and passed 31 fracturing stages to re-establish the fracturing program.

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...
