Key VOM Message:
EV’s industry leading camera technology in partnership with an electric line tractor, allowing for real time transmission of video to surface while simultaneously tractoring downhole. This month’s video demonstrates EV’s leading technology partnerships, and how successfully integrating cameras into well intervention can save time and reduce risk for horizontal well inspections.
This Video of the Month is from a new, horizontal offshore oil producer. The operator experienced multiple unexpected completion issues prior to stimulating the well including a liner leak and unknown stimulation sleeve status.
To investigate further, the client decided to deploy EV's Optis® HD E-line camera on an electric line tractor, enabling high quality video to be acquired in real-time simultaneous to tractoring.
Video while tractoring ensured that the source and root cause of the leak could be identified effectively and efficiently simultaneous to tractoring. High quality down view video instantly showed oil entering through the high side of the completion at 20950ft (00:00:10). The root cause of the leak was seen to be a backed-off liner connection with debris build up observed on the low-side directly above the collar. Armed with this information, the operator decided to perform an injection test into the leaking connection.
As the Video While Tractoring system progressed down the well, a number of stimulation sleeves were confirmed to be closed. However, sleeve #23 that was assumed closed from a previous log was also found to be partially open
Based on this information, an electric line mechanical interventional was planned to close the sleeve prior to stimulating lower zones.
Finally, a damaged protection sleeve was unexpectedly located at 23314ft preventing further well access beyond this point. This information proves valuable for future well interventions and potential zonal shut-off planning.
This case study illustrates how EV’s Video While Tractoring system allowed the customer to continuously inspect a long interval of interest in a high temperature well without the requirement to stop and start the system. Although a number of logging runs had been completed prior to the camera being deployed, the high quality, visual information provided the operator with conclusive evidence of sleeve status and completion condition, thus enabling decisive action to be taken.
