Drilling
Research by Enervus sees early 2026 permitting activity for the carbon capture and storage wells pointing to a growing approval queue, even while the rate of applications eases.
The new guidelines were released prior to reports that enhanced geothermal developer Fervo Energy experienced a blowout in Utah with no reported injuries.
BP said it expects to keep the Azeri-Chirag-Gunashli (ACG) project in production into the 2040s by tapping into separate nonassociated gas reservoirs.

Scaling buildup inside wellbores is a serious production problem that dramatically reduces the well productivity index. This issue has a significant cost across the industry, mostly associated with loss of production or additional operations such as well intervention. -
By using the four converter-battery systems, the operator estimates it will be able to reduce the runtime of the rig’s on-platform diesel engines by 42%, cutting CO2 emissions by 15% and NOx emissions by 12%.

The complete paper documents the development, laboratory- and field testing, and lessons learned from a project to evaluate coated centralizers.

Optimizing horizontal well placement is not limited to identifying the most-favorable reservoir, but also involves identifying the ideal target window within that reservoir.

Drilling has become a complex operation that requires a multitude of tasks to be managed at the same time. Not surprisingly, then, drilling automation will gain momentum in the near future to deliver consistent execution and performance safely and with good wellbore quality.

This paper covers the 7-year history of drilling-fluids application in a reservoir drilling campaign offshore Abu Dhabi, from the early use of a solids-free, brine-/water-based mud to the recent application of nondamaging, nonaqueous fluids (NAFs) with micronized acid-soluble ilmenite.

This study focus on the design and evaluation of a customized water-based mud (NP-WBM) using silica oxide nanoparticles (SiO2-NPs) and graphene oxide nanoplatelets (GNPs).
-
Recent research has put extensive focus on the magic of graphene in drilling fluids. Graphene, because of its thermal, electrical, chemical, and mechanical properties, improves mudcake stability and minimizes fluid loss that eventually reduces formation damage.

The advent of the rotary-steerable system (RSS) introduced an efficient way to drill both current and future wells. However, current tools still fail to replace positive displacement motors (PDMs).
