Abstract: With the development of drilling technology and reinforced exploration and exploitation of unconventional reservoirs, there has been a great increase of complex wells. Meanwhile, however, consequent casing wear is and will ...

Abstract: AbstractCasing deformation in horizontal shale gas wells is a critical issue during multistage hydraulic fracturing. This study investigates the impact of fracture density and its nonuniformity on casing deformation using ...

Abstract: According to the tubing string failure statistics in the oilfield, fatigue crack of tubing joint thread in high temperature high pressure (HTHP) ultradeep gas wells remains a problem because it can cause tubing strength ...
