Optimize project economics, well design and drilling efficiency with application of SET solid expandable technology.

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...

  • Operator was experiencing trouble formation caused by narrow pore pressure/fracture gradient window which caused casing to be set higher than planned.
  • Operator decided that expandables were the way to go.
  • All of the customer's operating objectives were met.

The customer was sidetracking the well, and unable to run their 16-inch liner. The 13-5/8 inch and 11-3/4 inch casing were both set high, which would compromise the originally planned 8-1/2 inch hole size.

 

The operator selected a 9-5/8 x 11-3/4 in. SET®...

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...
