Frac gauge and carriers

Patented design allows for unobstructed flow and consistent flow rates when space is tight.

When space is the issue, Reservoir Group’s Frac Gauge is what you need.

Our patented design builds the pressure sensor into the carrier so flow rates aren’t obstructed. Available in various tubing sizes, this pressure gauge is ideal for slimhole applications where space is tight.

Features

  • Non-intrusive sensor deployment does not affect the flow of the well
  • Full-bore flow area through ID of gauge
  • Capability of monitoring tubing and/or annulus pressures
  • Provides maximum tensile strength for gauge carriers

Applications

  • Frac monitoring
  • H2S and CO2 corrosive environments
  • Production optimization
  • Slickline operations
  • Static, flowing and build-up surveys
  • Stimulation monitoring

Specific Applications

  • Slimhole applications
  • Non-intrusive gauge for monitoring downhole pressures during frac and other stimulation work
