Drilling
Updates about global exploration and production activities and developments.
One major challenge for drilling-fluid engineers is the design and management of optimal drilling-fluid formulations in emerging frontiers—fractured formations and high-pressure geothermal environments. Recently, operators have leveraged cutting-edge technology such as machine learning and expanded data-driven techniques to facilitate the development of new drilling-f…
This research aims to develop a fluid-advisory system that provides recommendations for optimal amounts of chemical additives needed to maintain desired fluid properties in various drilling-fluid systems.

As I read through the abstracts and papers that have been presented in the past year, I notice several key themes: verification of cement placement, development of new materials as a barrier, development of new additives to improve the cement barrier, and enhancement of existing techniques.

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.
-
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.”
