Drilling
The firm's first-quarter rankings evaluate drilling performance across multiple measures, including total drilled measured depth.
After acquiring the block more than a decade ago, Petrobras has finally found oil in the deepwater area of the Equatorial Margin with the Morpho-1 exploration well.
More than 900 drilling and well professionals from 30+ countries gathered at APDT 2026 in Bali to explore how AI, automation, and advanced well technologies are driving safer, smarter, and more efficient drilling across Asia Pacific.

Bottomhole assemblies (BHAs), as part of the drilling system, have dominating effects on the functionality and effectiveness of other system components. BHA design, usage, and monitoring must promote drilling-system compatibility, efficiency, and reliability. -
Correct placement of the rotary-speed sweet spot of a bottomhole assembly (BHA) provides multiple benefits toward achieving the ultimate goal of drilling to section total depth in a single trip.
-
Microdoglegs are a natural effect of any vertical or directional well that can explain a wide variety of downhole problems.
-
A new fatigue-management work flow provides drillers with a tool to simulate and predict the life expectancy of bottomhole assemblies (BHAs) before fatigue causes problems.
-
Advancements in extended-reach drilling continue from the ExxonMobil-operated Sakhalin-1 project. The latest “super complex” horizontal well stretches 15,000 m, which partner Rosneft says is a “world record.”
-
Researchers have developed a novel water-based-drilling-fluid system compatible with deepwater HP/HT wells in the Lingshui Block on the basis of a conventional drilling fluid and further optimization.
-
new drilling method provides a solution for challenges encountered in drilling of long horizontal wells, incorporating a dual drillstring with a separate channel for the return fluid from the well.
-
The complete paper discusses the advancements in mud-displacement simulation that overcome the limitations of the previous-generation simulator and provide a more-realistic simulation in highly deviated and horizontal wells.
-
A supramolecular viscosifier package has been developed that uses noncovalent associations between additives to enhance the thermal resilience of divalent brine fluids.
