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.

Our industry is involved in the development of several automated tools and processes to improve the quality of drilling operations. -
The paper demonstrates the successful application of advanced automated managed-pressure-drilling (MPD) technologies on the Dover well close to Fort McMurray, Alberta, Canada.
-
The development of the Kanowit field offshore Sarawak, Malaysia, requires the drilling of two subsea development wells with a semisubmersible rig.
-
It has been an impressive comeback for a technology that once stood on the brink of failure. The upstream oil and gas industry has largely resolved crippling technical challenges that shortened the life of fiber-optic cables in downhole applications and is now working on a big encore.
-
The list of wells drilled using dual gradient includes one drilled in the “eastern Gulf of Mexico,” which could be more precisely described as offshore Cuba.
-
The Troll field is one of the largest gas producers discovered off Norway, but ensuring its long-term future required finding ways to drill wells in an increasingly fragile formation to develop its rich oil reserves.
-
Two years ago, as drillers approached the bottom of a deepwater well in the Lula field, they were stopped again and again by total drilling fluid losses.
-
Dual-gradient drilling has long been described as the drilling method of the future for challenging offshore wells. Now, indications show it could start being used with some regularity.
-
The variables defining drill-bit performance cover a lot of ground. There is a lot of attention given to cutters studding diamond drill bits, but just as important are what is in the rest of the drillstring and the decisions made by the driller.
-
A previous attempt to drill an exploration well in ultradeep water in the Gulf of Mexico (GOM) did not reach its objective.
