Identification of obstruction
During a well intervention run, the wellbore was blocked for unknown reasons.
The Vision WellCAM®️ was run to identify the cause of the blockage.
The ball dropped to open a sleeve, was still sitting in the ball seat.
The Vision WellCAM®️ was conveyed on tractor (logging while tractoring) providing real time images at surface.
On the high side of the wellbore we see the well producing oil during the camera operation.
The WellViewer™️ inclinometer shows the inclination to be approximately 90 degree horizontal.
This video shows a WellCAM® inspecting a GLV for damages and potential scale. Since the camera has a continuous side-view capability, its possible to just run quickly trough the well and do the closer inspection in the recorded data.
This video shows images captured with a WellCAM® camera. The images shows the screen in a water well where they had experienced decreasing flow.
Since the WellCAM® have the ability to record continuous side view, doing closeup inspections of the holes is an easy operation.
The images, captured with a WellCAM® Drill Pipe camera, shows a tubing before and after milling operation. The WellCAM® Drill Pipe Camera is part of the standard Vision iO WellCAM® platform. It retains all the standard features including full hemispheric images with pan, tilt & zoom ability allowing down-view and side-view of the wellbore on the same tool.
The camera is protected from impact using a bump absorber that allows the camera to retract inside the running sleeve.
Typical applications for the WellCAM® Drill Pipe Camera includes;
BOP inspection, wellhead inspection, identify fishes, riser inspection, tubing hangers, sealing areas and subsea conductors.
This video shows images captured with a WellCAM® E-Line camera. Here we can clearly see the slips marks made by a stroker tool.
The video shows images captured with a WellCAM® E-Line camera. The main objective on this run was not to inspect this valve, but since the WellCAM® records full hemispheric images, its possible to pan & tilt even after the job is done.
Full hemispherical view
The Vision iO WellCAM® uses an extreme wide angel lens in combination with a custom made software to ensures full sight coverage in both memory and e-line mode.
With 180 degrees side view in full 360, nothing will be overlooked in its way trough the well.
The Vision WellCAM® platform can be run on all types of conveyances.

This was run on CT in memory mode and actually proved to be parted tubing. The CT team had been milling between 2 to 3 weeks and concerns came up as to whether they were inside the liner, creating an opening or if the well was scaled up. Due to the fact that the expected results were not achieved a decision was made to run the WellCAM® downhole camera. The camera run provided feedback which led to the conclusion that the CT did not enter the lower section of the liner, but instead ran outside, resulting in a sidetrack of about 160 meters.
Oil seeping through cement plug
Images captured with a WellCAM® E-Coil camera.
Same run as above (Washing Cement Plug). When pumping was stopped it was observed that oil droplets started to seep through the cement. This confirmed that the WellCAM® was also good at confirming small leaks.
