1920 X 1080 Water Shutoff

Water shut-off

The best way to tackle unwanted water production is to shut it off downhole

Water shut-off

Welltec offers versatile solutions to meet the diverse challenges of water shut-off, covering everything from completion to intervention.

Applications

  • Leak remediation utilizing the award-winning Isealate Springblade Patch.
  • Setting straddle packers, shifting sliding sleeve doors, shifting flow control devices utilizing mechanical services.
  • Multi-zone horizontal completions, utilizing Density Activated Recovery (DAR) technology.

Award-winning technology

Due to various factors such as geological conditions, operational conditions, materials, design, and old age, the reality is that ‘minor’ leaks in production tubing are a common problem, where corrosion or other damage leads to unwanted issues like water production/ingress, or loss of integrity. 

A fast and efficient solution with a minimal footprint is ideal, and this is achieved via lightweight e-line deployment of the award-winning Isealate Springblade Patch.  This makes leak remediation possible with only a 4 mm reduction in the tubing's inner diameter, and multiple patches can be set on a single run - see video.

Welltec solution benefits

Deployment of an Isealate Springblade Patch allows for patch-thru-patch applications with an ulta-slim 4 – 10 mm thickness, offering total flexibility for customized relining, repair, and well integrity.

Welltec has performed many rigless downhole water shut-off operations with the use of Well Tractor® technology.

In combination with Well Stroker® and Well Key® tools, the benefits of this approach to water shut-off include: 

  • Downhole water shut-off
  • Straddle packers set on electric line hydraulic stroking tools
  • Sliding sleeve doors and flow control devices shifting with Well Stroker and Well Key
  • Rigless intervention
  • Minimal footprint on offshore platforms
