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.

The complete paper presents a case study in which offline cementing improved operational efficiency by reducing drilling times and provided significant cost savings. -
This study used ultrasonic logging to evaluate reference barrier cells constructed with known defects. The cell concept was developed with an emphasis on low cost and ease of use.

This case study discusses the methodology that underlies the successful determination of the depths and the radial locations in the outer casing strings of multiple leaks in an offshore well.
-
This paper describes the mobilization of a snubbing unit and blowout preventer (BOP) stack in the Middle East that enabled a well with an underground blowout and surface broaching to be brought under control within a short time.
