Drilling

The effects of aging and temperature on the performance of one-part “just add water” granite based geopolymers are studied for application in well cementing and abandonment. Further studied is the role of zinc as a strength enhancer over a long curing period.

New studies examine whether two innovative well designs should have a bigger role to play in the race to get more value out of tight rock reservoirs.

Backed by more than $28 million in fresh investments, XGS Energy is prepping to introduce a new technology called thermal reach enhancement.

This paper describes an autonomous drilling approach using an autocurve-drilling mode to automatically drill curved sections without human intervention and complete autonomous well construction.

This paper presents an approach for automatic daily-drilling-report classification that incorporates new techniques of artificial intelligence.

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…

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…

The oilfield service giant said it has taken another big step toward fully autonomous drilling operations in its latest project offshore Brazil.

The companies have integrated their platforms in an effort to increase flexibility and interoperability.
