Drilling
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 findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.

Operators at a UAE field experienced several challenges while cementing production sections. A systematic approach was applied that used standard cementing best practices as a starting point. -
As the resources that the industry develops become increasingly challenging, access to a broader range of options and new and developing approaches allows more-efficient and -effective recovery.
-
The influx-management-envelope (IME) concept is an advanced, innovative way to assess influx conditions in managed-pressure-drilling (MPD) operations, offering an improved tool for the decision-making process.
-
This paper discusses the successful design, laboratory testing, and performance of an innovative, low-solids, organophilic-clay-free invert-emulsion fluid (OCF-IEF) used to drill the reservoir section of an extended-reach-drilling (ERD) well.
-
Current long-reach technology already has a large effect on oil recovery. Many possible improvements, however, remain, and we see new contributions every year.
-
The Peregrino project, located in the post-salt zone of the Campos Basin, presents immense challenges for drilling extended-reach wells. This paper shares challenges imposed by the well profile and downhole environment on the design and execution phases.
-
This paper presents a concept that enables simultaneous drilling and completion, with an aim to extend well reach substantially and with an ultimate objective of constructing 30-km-long production wells.
-
A producer and a service company have collaborated to develop a downhole system to merge multilateral technology and intelligent completions to create “smart laterals.”
-
As it works to increase production to 1 million BOE/D, Permian mainstay Pioneer is taking a methodical approach to sustaining capital efficiency.
-
A new holistic approach to optimizing wellbore economics is bridging the gap between planning and execution and bringing well construction into the digital era to improve data use, enhance collaboration, boost efficiency, and increase safety.
