Drilling
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.
This year, we observed a notable increase in activity centered on physical technologies, including cementing tools, zonal isolation barriers, and cement evaluation systems.

Our drilling process is punctuated with discontinuous events that can disrupt the operational flow of the perfect well. Three papers have been selected to provide insights into some of these nonstationary processes that cause bit runs to fall short of perfection. -
Westwood Energy analysts suggest operators have an opportunity to secure rigs at lower rates for their 2027 drilling programs.
