The Sichuan basin’s shale gas fields demonstrate elevated seismic activity, which poses a significant challenge in the development of shale gas. Besides, casing deformation emerges as a prominent ...

The installation of steel casings in riprap-covered macro-tidal estuarine mudflats is governed by a complex interplay of soil, tidal and pore-water pressures, frequently causing the casing to refuse ...

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 ...

A new method to design casing strings is based on predicted and actual wear of strings in the Tarim oil field, China. Casing wear during drilling reduces casing strength, especially collapse strength, ...

Conductor casing Conductor casing is the first string set below the structural casing (i.e., drive pipe or marine conductor run to protect loose near-surface formations and to enable circulation of ...
