This video showcases how the application of LeakVA, supported by Optis Infinity technology, helped an operator in South East Asia locate & evaluate a downhole leak in their gas well.
Leaks can undermine the production potential of a well and become a serious risk to safety and the environment. The most common leaks occur between the production tubing and production casing annulus, having an immediate impact on the safe operation of a well, but often proving difficult to pinpoint with conventional production logging and integrity evaluation services. For well operators, it’s crucial to determine the location, size and scale of any leaks, as implementing the correct remediation technique can avoid costly well workover operations and rapidly restore production to its optimum level.
The presence of sustained ‘A-Annulus’ pressure was reported during routine pressure diagnostics. The pressure was proving difficult to bleed down to a minimum. With the integrity of the well seriously compromised, the operator needed to quickly understand the root cause of the pressure build-up, to enable effective remediation and safe guard production from the well.
Having performed a leak detection survey, EV’s Optis Infinity Memory Camera was run on Slickline with both downview & sideview footage acquired to confirm the leak location, measure its extent and evaluate the condition of the surrounding area. Armed with this information, the operator would be able to understand the root cause and the severity of the issue, enabling them to select the most appropriate remedial action.
