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.

Recent research shows that, in addition to hardness, other rock properties, such as lithology types, heterogeneity, and abrasiveness, have equal importance in bit evaluations. Consequently, the discussion must move from rock-strength analysis to rock-drillability analysis. -
Helmerich & Payne’s first 100 years have required constant reinvention. Now the company hopes its new drilling software platform built on the acquisitions of two startups will propel it through the next century.

Visuray is using its unique X-ray technology to improve downhole imaging.

This paper demonstrates a work flow to determine optimal lateral lengths and trajectories in the Midland Basin by studying the effect of the lateral length and trajectory on well production.
-
This paper presents an approach to modeling the cuttings-lag-depth distribution caused by the dispersion of cuttings-transport velocity in directional drilling.
-
This paper describes a new approach to evaluating the effectiveness of the rotary-steerable-system (RSS) steering mechanism on wellbore tortuosity in horizontal wells.
-
The shift toward lower prices in the industry has resulted in the necessity for more wells to be drilled at lower cost. Numerous other industries have shown that they are able to constantly reduce cost per unit. Where do we stand today and what will the future possibly look like?
-
With drilling on the rise, US oil production is expected to continue to increase. However, many industry professionals are concerned that the “brute force” model, which has seen a massive influx of capital flow into completion and hydraulic fracturing operations, is not economically sustainable.
-
With the arrival and development of rotary steerable systems in the late 1990s, the industry thought that drilling a perfectly smooth and controlled trajectory would not be an issue. Two decades later, we’re still talking about wellbore quality, especially with long and complex horizontal wells.

The use of organophilic clays as additives to provide proper rheological and filtration properties in nonaqueous drilling fluids (NADFs) has long been a topic of study. This paper introduced a modified rectorite designed for biodiesel-based drilling fluid (BBDF).
