Drilling
This paper presents laboratory-testing methods and evaluation criteria designed to improve understanding of both the origin and extent of formation damage associated with CO2 injection.
This work introduces an analytical model for nonisothermal CO2 injection that accounts for both Joule-Thomson cooling and interformation heat exchange.
As managed pressure drilling gains traction, its principles are influencing a wider range of well-construction activities.

This paper reviews a successful managed-pressure-cementing (MPC) operation and presents findings and lessons learned. -
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.
-
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.
-
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.
-
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.
-
An early commitment to integrate MPD into an HP/HT drilling operation can make MPD more than just an enabling tool and turn it into a performance tool that offers significant operational benefits.
