Imaging of Damaged Casing

Client Case Study

While trying to set a plug during the abandonment of a well, a Permian Basin operator encountered an obstruction before reaching the intended depth. Already familiar with the VR90 Downhole X-Ray Diagnostic Service from a previous job, the client engaged Visuray to diagnose the cause of the obstruction.

Visuray's operations team reached the well site within hours of the callout. The VR90 tool was run in hole to a depth of 1,960 feet. Real-time images produced at this depth showed a portion of the casing had collapsed and was obstructing the well. The VR90 tool's images also revealed a hole in the casing, which allowed debris to further obstruct the well. A dimensionally-accurate reconstruction of the damaged casing demonstrated that the diameter of the intact casing was about 3''. This diagnosis made it clear that the client's initial plan to mill through the obstruction would possibly compromise the integrity of the casing further, and a safer course of action would be to simply plug the well above the obstruction.

Visuray provided the client with a fast, reliable diagnosis of their obstruction without any costly or time-consuming preparation of the well. Visuray's VR90 Downhole X-Ray Diagnostic Service revealed the nature, dimensions, and state of the obstruction, allowing for a more efficient and cost-effective well intervention.
