Casing/cementing/zonal isolation
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 a case study of oriented tubing-conveyed perforation followed by an acidizing operation to overcome technical challenges posed by a depleted reservoir targeted for a carbon capture, utilization, and storage project.

This paper introduces a fit-for-purpose surface-controlled formation-isolation valve (SFIV) designed for the temporary well suspension required for this strategy. -
Deepwater cementing becomes increasingly challenging as drilling operations move to greater water depths and more-remote locations.
-
ADMA-OPCO had integrity problems in one of its gas wells, and abandonment was the only option available to restore the integrity of the offshore multiwell jacket and revive adjacent wells.
-
In 2012, the number of unconventional tight gas/shale and high-pressure/high-temperature (HP/HT) papers continued to grow. This year, we had some very interesting developments in these and other areas of well construction.
-
The Eagle Ford shale in Zavala County, Texas, is similar to many high-carbonate-content oil-shale formations.
-
To maintain zonal isolation throughout the life of a high-pressure/high-temperature (HP/HT) well, the cement sheath must perform reliably at temperatures that can exceed 315°C.
-
The Granite Wash formation presents several challenges in drilling the build section from a vertical open hole to form a lateral.
-
As operators continue to drill into deeper and more-extreme formations, the demand for technologies suited to these environments increases.
