Drilling
Conflict‑driven price gains may be offset by higher costs, supply‑chain risks, and a limited appetite for new drilling activity.
While some idle wells may be brought back into production, many will be plugged and abandoned. This paper considers repurposing certain idle oil and gas wells by using their empty steel casing for the disposal of nuclear waste.
The companies' combined technologies enable real-time control of well placement, hydraulics, and rig operations.

This paper describes preplanning, execution, and results of drilling extended-reach wells with a large-bore design of 12¼-in. as the main stepout section and deploying 9⅝-in. casing at a shallow true vertical depth of 4,200 ft.

The domain expertise and technologies in the oil and gas industry such as integrated project planning and operating, extended-reach drilling (ERD), high-pressure/high-temperature drilling tools, multilateral drilling and completions, geomechanics, flow and thermal dynamics modeling, and artificial intelligence have been fueling the ongoing march for new records on ERD…

This paper presents a laboratory-based study that compares the three methods to measure static gel-strength development that are widely accepted in the industry.
-
The objective of this paper is to review selected completions to provide insights for adoption of multilateral technologies, including lessons learned, operational experience, and recommendations.

The authors discuss a modified ultrasonic-cement-analyzer (UCA) vessel that allows assessment of slurry sealing performance under representative downhole conditions while running otherwise standard UCA equipment.
-
In 2022, the topics of the cementing and zonal isolation papers published were generally similar to those presented in previous years. A noticeable departure from previous years, however, was that many of the authors emphasized that their work would result in a reduction of greenhouse-gas emissions.

This paper compares the sealability performance of an expanding geopolymer with that of an expansive commercial cement in terms of the shear bond strength and the hydraulic bond strength at curing conditions of 25℃ and 34.5 bar.

Nabors is connecting Corva’s platform to its universal rig controls and automation platform, allowing apps built and developed in Corva to monitor and control any rig equipped with the platform.

EcoShield also reduces carbon footprint of well construction over traditional cement systems.

While the ongoing technical studies and technology developments in the area of formation damage are heavily focused on key damage-mechanism scenarios during drilling and production, such as drilling-fluid-induced damage, scaling, clay swelling, fines migration, and incompatibility of fluid/fluid and fluid/rock in conventional sandstone and carbonate reservoirs, there …
