Casing wear is an increasingly typical problem that leads to a decrease in collapse resistance in deep wells, ultradeep wells, horizontal wells, and extended reach wells. Casing wear is an ...
New equations for calculating the collapse strength of worn casing can aid future casing string design. During any drilling, it is inevitable that drill pipe rotation and tripping will cause casing ...
During high-intensity injection and production in underground gas storage (UGS), the biting behavior of packer slip teeth on the casing’s inner wall can cause damage, leading to anchoring failure and ...
