Drilling
The London-headquartered independent acquires position in the US Gulf while preparing Zama for final investment decision.
This study identifies critical knowledge gaps in wellbore integrity and underscores areas that require further investigation, providing insights into how wellbores must evolve to meet the technical demands of the energy transition.
This study illustrates the new capabilities, tailored for CO₂ storage applications, of a modeling framework that provides a quantitative, risk-based assessment of the long-term integrity of legacy plugged and abandoned wells.

Well control training programs for deepwater drillers and key rig personnel are undergoing a major overhaul that has been years in the making. -
Recent experience with a newly introduced sampling-while-drilling service has shown that it is possible to make reliable downhole formation-fluid-property estimates during sampling-while-drilling operations.

After the 2010 subsea blowout of the Macondo well that resulted in 11 deaths and the worst oil spill in US history, early kick detection technology found itself at the top of the wish list for regulators and offshore companies seeking to avoid similar accidents.
-
Researchers at the University of Texas at Austin (UT) have set an audacious goal to halve the time, cost, and number of rig personnel required for drilling every type of well, from unconventional shale to ultradeepwater.
-
Technology developers are working on a new ultrasonic flowmeter for drilling fluids aimed at obtaining better measurements than current systems with far fewer disruptions to rig systems.
-
There is a lot of information buried in drilling reports written every day, but little of it appears in computer databases.
-
For the past several years, automated drilling has promised to deliver major improvements in drilling performance. But the technology is facing new obstacles that might affect its progress and commercialization.
-
For the past quarter of a century, underbalanced drilling (UBD) has been a niche technology known to many and practiced by few. It has seen acceptance in the North Sea, where UBD is used to drill through depleted reservoirs.
-
There are headlines every day that discuss the ethics and safety behind oil and gas operations, particularly hydraulic fracturing.
