Drilling
Operators aren’t rushing to drill, even as the closure of the Strait of Hormuz drives oil prices up.
The authors reach conclusions that the industry should define a standard testing method to improve swelling performance, including validation of repeatability, to complement existing guidelines.
This paper establishes that the use of a dual-gradient fluid column during the running of large casing in an extreme-reach deepwater well is an effective method to overcome drag and enable the casing to reach total depth.

The Sidri 36 appraisal well confirmed the downdip westward extension of the Sidri 23 discovery announced last July by the Italian major. -
The Orca-1 and Marsouin-1 wells have derisked up to 50 Tcf of gas initially in place from the Cenomanian and Albian plays in the BirAllah area, more than sufficient to support a world-scale LNG project, partner Kosmos Energy said.

The hybrid power technology cuts fuel consumption and boosts the dynamically positioned rig’s station-keeping reliability, the drilling contractor says.
-
Measured-pressure approaches have offered much promise for some time but have been slow to reach widespread application. A spate of technical developments, deployments, trials, and applications, however, recently has pushed measured-pressure drilling and its nuanced variants to their full potential.
