Casing/cementing/zonal isolation
This case study from ARC Resources and DarkVision outlines the use of acoustic imaging tools in two active fracturing programs in Canada to monitor well casing deformation.
This case study outlines a full-scale testing program focused on the behavior of thermal casing connections subjected to severe bending and low-cycle fatigue loading.
As managed pressure drilling gains traction, its principles are influencing a wider range of well-construction activities.

This paper describes the first application of the 10¾-in. CV in a deep-well sour environment. -
The most common method used for the placement of cement plugs is the balanced-plug method using drillpipe, tubing, or a combination of both.
-
Many good well-construction-technology papers came out last year, as well as a couple on older technologies that either had not been published earlier or had been released and were underappreciated.
-
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.
