TO ADDRESS the issue of sand control failure in wells, independent global completions service company Tendeka, has launched a new cost-effective single trip sand control solution.
The Filtrex remedial sand control system provides the flexibility to be installed thru-tubing, through the tightest of restrictions. The first of its kind, the Filtrex system provides the ability to perform sand cleanout whilst installing the tool.
Using an open-cell reticulated depth filter, the tool is run in hole compressed, once set, the filter will expand into the casing or failed screen filling the annular gap. The filtration is fully protected during deployment and will not be exposed until at the correct location. The tool will retain sand whilst allowing fluid flow through the depth filtration media. Once set, the tool requires no further intervention.
Eilidh McKay, technical support manager at Tendeka said: “Sand control failure is a common occurrence in the industry, and as such, there is a challenge to regain sand control in existing damaged completions without the requirement to perform a workover.
“The process of thru-tubing sand control can be costly and time-consuming, requiring the removal of sand prior to installing a sand control solution, with most existing solutions enabling the wellbore to refill with formation sand reducing productivity, and are susceptible to erosion failure.”
In mature basins, sand issues account for eight per cent of all shut-in wells either due to failure of the existing sand screen or onset of sand production due to depletion or water production.
Filtrex prevents the need to perform a full workover. It will be the only tool on the market that can perform sand cleanout and install a permanent solution at the same time which prevents multiple trips.
Brad Baker, CEO of Tendeka added: “We have recently invested in a sand lab at our Aberdeen headquarters and have looked outside the box to come up with a simple and effective solution that can have a real impact on an industry-wide issue.
“We are known in the sector as sand management specialists and we are already seeing interest from several operators around the world.
