Drilling

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.

The authors of this paper discuss deep closed-loop geothermal systems as an alternative to traditional enhanced geothermal systems for green energy production that is globally scalable and dispatchable.

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.

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 …

This paper describes an openhole wireline-logging operation in a deepwater Gulf of Mexico well in a high-pressure/high-temperature slimhole environment using water-based reservoir drilling fluid.

The authors of this paper present results of a study that examined formation-damage mechanisms caused by drilling fluids in tight reservoirs in onshore oil fields in Abu Dhabi.

The paper presents predicted vs. measured wear for six wells in the Culzean field, a high-pressure/high-temperature gas condensate field in the central North Sea.

The authors of this paper present a laboratory-based model to determine the detachment of authigenic and detrital particles in formation damage.
