Lost BHA
On a land well in the USA during a routine intervention operation, the customer twisted off the BHA during a drilling campaign. The only indication of a problem was that the operator was not making hole so they pulled out to investigate further. Several over-shots were deployed to retrieve the BHA with no success.

EV was called to run their surface read-out e-line downhole camera, the Optis™ Electric Line system. After running through casing collars and past the casing shoe, the footage clearly shows the twisted off drill pipe in 6 3/4" casing, and just below the fish, the part-sheared pipe. The images showed the customer the problem and the nature of the fish. In this typical application, the camera can be run at the same time as a spear thus helping the customer speed up the fishing campaign by guiding the spear into the broken BHA. Many US$$$ were saved by running the camera. This is a great example of how running a downhole camera has tangible benefits in reducing time, saving money and reducing non-production time.

Good wellbore preparation is key to gaining successful images. The client fully understood this requirement and was proactive in assisting EV in developing the operational programme which led to the successful run.

EV is an independent company enjoying a four-fold growth in the last year.
