Drilling
A report commissioned by Havtil, the Norwegian Ocean Industry Authority, calls for better dialogue regarding pore-pressure uncertainty and higher-end drilling techniques like managed pressure drilling as methods to reduce the risk of well-control events.
This guest editorial addresses the need for high-temperature directional drilling technologies as the number of rigs used to develop next-generation geothermal wells is set to rise in the coming years.
This study aims to systematically assess casing integrity and corrosion risks associated with CO2 injection in oil-recovery operations.

This paper presents an approach for automatic daily-drilling-report classification that incorporates new techniques of artificial intelligence. -
The authors of this paper present the results of implementing a rig-automation solution applied to 20 wells in Ecuador in 2022.

Casing deformations are common in the south-west shale regions of China and the Middle East, where the widespread use of 5.5-in., 26- and 26.8-lb/ft casing is the norm. In these regions, the majority of frac plugs are designed with an outer diameter (OD) of 4.055 in. or slightly larger, which frequently encounter restrictions resulting in the loss of bottomhole assemb…

In recent years, operators and service companies have optimized drilling activities and reduced operational costs by accelerating the deployment of digital solutions. Among other applications, predictive data analytics are commonly used to estimate rock properties, reduce operational uncertainty, improve equipment maintenance processes, and optimize scarce human resou…

Typically, oil and gas producing wells are abandoned toward the end of their life cycles with reservoir pressures depleted compared with the virgin pressures. Carbon capture and storage projects, however, present different operating conditions.

SponsoredWith more surface facilities and infrastructure in oil and gas fields, well casing integrity is becoming an even bigger challenge. This article sheds light on the optimum way to deal with the increasing casing integrity challenges in the Middle East through field monitoring and time-lapse casing-integrity and corrosion-inspection logging.
