"The Filtrex system is unique for two main reasons. One is the filter media that compresses within the running tool during deployment and then expands providing full compliance to the casing diameter or damaged screen. Secondly, it can be deployed into a live well, without the need to perform a full workover. So intervention timings are potentially cut in half, with associated run charges reducing by at least 50%."
Tendeka saw the need to develop the remedial sand control system after holding a meeting with a familiar feel to it.
"We held a Dragon's Den event within our technology group with teams coming up with ideas for new technology. The team presented plans to the Dragons, with the hope of securing R&D funding.
"A reliable remedial sand control system has always been the holy grail for addressing sand ingress and restoring productivity in failed sand control completions.
"The cost and impact associated with this are enormous. In mature basins, for example, sand issues can account for up to 10% 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. Hence, we knew this was an area we had to address."
So the winners stood out to the Dragons, and given the green light to research and develop their idea.
"The development of Filtrex has been quick compared to many new technology developments, within two years from proof of concept to kicking off qualification testing. To develop, test and qualify Filtrex, Tendeka invested in a purpose-built sand laboratory in Aberdeen to perform sand retention testing. The main challenge for developing Filtrex was that industry-standard, sand-retention test setups were not suitable. We had to create a standard for evaluating the Filtrex filter media. We are currently at the final stages of development before full commercialisation and have engagement with several operators for field trial.
"Initial trials of the filter media were all hugely successful, which was unexpected for a new development project!
"We built on the initial success of the sand filter media and started looking at the tool as a whole. We wanted to determine how to deploy it and how to anchor the assembly in the well. By performing further repeatability testing, as well as manufacturing trials, we could learn the most effective techniques to build the tool. With the development of our sand lab, further trials were conducted on the filter media to compare to the performance of standard mesh/wire wrap screens.
"Our team at Tendeka sees the benefit that this technology is bringing to the industry, particularly in maximising economic recovery. I'm looking forward to seeing the papers we receive on remedial sand control techniques as I feel this is an area of the industry where we can really learn from each other and push the technology even further."
