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 ...
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 ...
A robot's attempt to get a sample of the melted fuel at Japan's damaged nuclear reactor is suspended
This photo provided by the Tokyo Electric Power Company Holdings shows what they call a "Telesco-style" extendable pipe robot on July 10, 2024. (TEPCO via AP) (Uncredited) TOKYO – An attempt to use an ...
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 ...
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 ...
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 ...
An attempt to use an extendable robot to remove a fragment of melted fuel from a wrecked reactor at Japan’s tsunami-hit Fukushima Dai-ichi nuclear power plant was suspended yesterday due to a ...
