Injection log data suggested that a number of perforations may have become plugged, resulting in poor injectivity performance. Possible explanations included salt precipitation, scaling or a build up of injected solids. With multiple possible scenarios, the operator needed a clear and detailed understanding of the situation downhole, to select and execute the most appropriate remedial action.
This video of the month comes from an operation in Canada, where an operator applied EV’s PerforationVA service to understand and overcome declining injectivity performance of a Carbon Dioxide disposal well.
EV’s Optis Infinity Hybrid system was deployed on E-Line to reveal the status and condition of the perforations downhole. With the ability to record 360 degree sideview video to memory, combined with simultaneous transmission of live video to surface, Optis Infinity Hybrid provides comprehensive answers in real-time, directly at the well site.
The camera was run in hole to a depth of 3200m, where the detailed real-time video footage confirmed the presence of salts across all of the perforated intervals. The 360-degree perspective provided by the four sideview cameras revealed the condition of each perforation in detail, and the extent of the salt build up.
