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, ...

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 ...

Photos that reveal the industrial design of Apple Inc.'s next-generation MacBook Pro notebooks have been making the rounds on the Internet since late last week, AppleInsider has learned. People ...

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 ...

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 ...

The mechanism of casing deformation during multi-fracturing in shale gas wells has emerged as a key topic of political and scientific discussion 1,2, due to concerns that this event would seriously ...
