Drilling
Westwood Energy analysts suggest operators have an opportunity to secure rigs at lower rates for their 2027 drilling programs.
The Essington-1 well is the first discovery in the Otway since 2021.
Ranger acquires American Well Services for $90.5 million, adding 39 workover rigs and boosting its fleet by 25%.

Field N is a complex heavy-oil field in the north of the Sultanate of Oman. The dynamic behavior of Field N is characterized by strong aquifer and is dominated by bottomwater drive. -
ADNOC’s drilling subsidiary has increased its rig fleet to 95 and plans to add “dozens” more by 2025.
-
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%.
-
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.
-
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).
-
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.
