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
