This video of the month showcases how the application of RestrictionVA, supported by Optis Infinity technology, helped a leading operator in Russia diagnose and overcome their wellbore access problems.
The operator experienced a restriction within their oil producing well during a production optimization intervention. The well has a history of corrosion, with a replacement wellhead recently installed as a result, and any further integrity issues would force the operator to plug and abandon the well. With multiple unsuccessful drift runs, and no clear indication of the cause of the hold up, the operator needed a clear understanding of the restriction to determine the future of the well.
EV’s Optis Infinity M125 system was deployed on slickline with both downview and 360 degree sideview footage acquired to diagnose the restriction and evaluate the integrity of the well.
The camera was run downhole to 44 metres where the detailed 360-degree footage revealed the cause of the restriction to be an over-torqued tubing connection. Downview footage revealed a clear change in diameter at the connection and, by assessing all remaining tubing connections, confirmed this to be an isolated incident. Thirteen individual measurements were made by an EV analyst around the ID of the restricted connection. Although the restrictions are relatively small, their apparent square-edged nature may have been problematic for the passage of some BHA’s.
