Abstract: Coiled tubing is widely used in oil drilling and production operations. However, extreme high stress variation of coiled tubing during the processes of pulling out, rolling in the reel, and ...

Abstract: An integrated technique has been developed to experimentally and numerically evaluate water control and production increase in a tight gas formation with polymer. Experimentally, polymer has been appropriately selected and ...

Abstract: The development of highly active and stable electrocatalysts is a major challenge for water electrolysis. In this work, we designed bimetallic nitrogen-doped carbon (NiCo-NC) materials with excellent performance, which ...
