Drilling
This paper presents a study that confirms glass-reinforced-epoxy-lined tubing as a reliable, cost-effective solution for long-term water-injection service in moderate-salinity offshore environments.
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.

A North Sea field development included installation of long 4½-in. completion liners in the horizontal reservoir sections of each well. To minimize overall risk, the operator planned to use managed-pressure drilling (MPD). -
A field well was designed, built, and used to demonstrate the concept of real-time monitoring of the flow of drilling mud and smart cement and the hardening of the cement in place.
-
This paper discusses an expandable-liner-hanger (ELH) system that provides liner rotation during the liner deployment and the cementing operation while providing a hydraulically energized liner-top seal upon setting.
-
Despite cement’s remarkable properties, the search continues for enhancements in the areas of cost and isolation performance. Efficiencies and enhancements have been explored even to the point of replacing cement with other materials.
-
The conductor anchor node (CAN) technology was introduced as part of the architecture for Centrica’s Ivory deepwater exploration well in the Norwegian Sea to optimize efficient operations for the well’s riserless section.
-
Aggressive drilling growth in the Permian and other shale plays belies the cost of those wells, which in many cases are in the red.
-
Deepwater operators continually face technical and environmental challenges to drilling and completing wells safely and efficiently.
-
The industry has developed a deep and healthy respect for systems-engineering processes and the associated full considerations during the deployment of new technologies. The result has been a significant improvement in the successful use and broader deployment of these attractive technologies.
-
This paper focuses on the application of radio-frequency-identification technology to enable an operator to eliminate an intervention run (or intermediate liner) for a 10,000-ft reservoir section.
-
One common issue among operators in determining whether to install a managed-pressure-drilling (MPD) system for a campaign is the significant upfront cost.
