Independent global completions service company Tendeka has partnered with diagnostic systems specialist TGT to combat the expensive consequences of sand control failure in wells.

The ‘Find Fix Confirm’ sand control collaboration will see that the diagnostic specialist’s Sand Flow product is used to exactly identify the locations of sand ingress within the wellbore.

Tendeka’s Filtrex thru-tubing sand control system can be used to quickly repair the damage.

In mature basins such as the UK Continental Shelf, sand issues account for 10% of all shut-in wells either due to failure of the existing sand screen or onset of sand production due to depletion of pressure or water production.

Tendeka Advanced Completions director Paul Lynch said: “The management and control of sand production is an inherent problem in the oil and gas industry. Often, the first indication of sand issues downhole will be as a result of detrimental effects that can occur at the surface such as fill-in separators or erosional damage to pipework, ultimately resulting in a shut-in well.

“Our Find Fix Confirm sand remediation service addresses both issues to offer a more effective, intervention-based solution.”

Tendeka’s Filtrex system is a ‘one-trip’ remedial solution that allows sand-free production to be efficiently restored.

It is capable of performing sand cleanout, as well as chemical treatments during the deployment of the live well.

Meanwhile, TGT’s Sand Flow system accurately locates sand entry to the wellbore. It provides a qualitative sand count and identifies problem zones, even in challenging flow conditions.

TGT chief marketing officer Ken Feather said: “Our Sand Flow diagnostics are powered by Chorus technology, which captures and decodes the acoustic signature generated by sand particles entering the wellbore to reveal sand ingress locations and sand count.

“Equipped with that information, Filtrex can be targeted to repair the breach, then Chorus can be deployed again to confirm that the breach is fixed. Overall, Find Fix Confirm enables better use of resources and more reliable sand control outcomes.”

In July 2018, Tendeka completed a successful field trial with a major operator to test its sand control technology Cascade³.
