... by the PCDS-I. The cumulative pumping and returning volumes of drilling fluid and their difference are calculated by a program and compared with the volumes of drilling tools, providing a new way to detect the overflow and lost circulation in the tripping operations. Data of other operators are monitored...

... Abstract Lost circulation is one of the frequent challenges encountered in the well drilling and completion process, which can not only increase well construction time and operational cost but also pose great risk to the formation. However, choosing the most useful treatments may still...

Sub-surface current events took place during times when the surface circulation was relatively weak and during times when surface currents were strong and affected by the NBC / NBC...

... Abstract Completions using inflow control devices (ICDs) help provide balanced production inflow, delay water and gas breakthrough, and extend the productive life of the well. For fluid circulation, displacement, and wash down, an ICD completion typically utilizes a washpipe or inner string...
