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...

Establishing and maintaining hydraulic integrity between liner hangers and the base casing in which they are set has long been one of the most problematic areas facing operators. With failure rates on pressure seals in overlaps now exceeding 40% in some regions, the need for a solution to this...

For years, the reduction of tubular inside diameter (ID), or “telescoping effect,” limited the exploration and production of oil and gas. Using conventional technology, operators faced significant loss of ID in the course of the normal drilling process, during reentry and deepening of existing...

Larger SET® Systems were designed to mitigate the risks inherent in drilling complex and exploratory wells.

Larger solid expandable systems are planned as a basis-of-design (BOD) in the upper portion of the wellbore. This enables operators to maintain internal diameter (ID) early in the...

Multinational Energy Company Equinor experienced damage to the 18-5/8 in. casing at approximately 740m (2,428 ft.) MD in a well on the Oseberg B field in the North Sea. The client required a repair solution that would cover the damaged section while providing post-expanded drift ID of at least...
