Several Russian oil field case histories have demonstrated that expandable-profile tubulars or pipes have proven to be an effective way to control formation caving and sloughing problems in ...

To produce slotted pipe, a pattern of very fine cuts is made right though the wall by a high pressure sand/water jet. When the expansion force is applied this pipe opens up to a strong but highly ...

The idea of using expandable pipe in oil wells, once just a promising notion, is starting to become standard operating procedure with the rapid evolution of this technology developed in Houston. In ...

Tatneft has developed guidelines for running expandable-profile liners in wells with complex geology, based on operations in Iran, China, and Tatarstan. Since the early 1980s, expandable casing ...

Threaded oil-well pipe or casing after expansion shows Von Mises stresses at maximum deformation. Red indicates highest stresses, not failure. Enventure engineers use nonlinear FEA from Ansys Inc. to ...
