Expro‘s solution
Expro Meters’ ActiveSONAR™ flow meter has been successfully deployed on drilling operations and has attributes that make it the ideal flow meter for this application.
Expro’s SONAR clamp-on flow meter technology attaches to the outside of the existing drilling fluids flow line. For the inflow measurement, the SONAR meter is well suited for installation on the standpipe, off the rig floor to conserve rig space and downstream of the mud pumps to provide a true measurement of the flow rate of mud into the wellbore. For mud returns measurement, the SONAR meter can be installed on existing pipework (the pipe must be full, so special consideration should be given to piping geometry to ensure the pipe is full of liquid at the measurement point). Due to its non-intrusive design, the SONAR meter can be installed and rigged down without flanging-in pipe work and shutting down the process. SONAR meters are calibrated to +/- 2% accuracy and can be, easily, interfaced to rig data collection system to provide real-time flow rates.
About SONAR
SONAR meters employ array processing techniques to determine the rate at which naturally occurring flow turbulence, known as coherent vortical structures, travels past an array of sensors. These coherent vortical structures are created by the flow in a pipe due to the pipe wall shearing mechanism, inherent in virtually all flow streams. These structures maintain their characteristic shape, or are coherent, for a sufficient flow length (20-40 pipe diameters) to allow them to be tracked as they pass through the sensor array. The speed at which these vortical structures pass through the array is a direct indication of volumetric flow rate.
The SONAR processing techniques make the resulting flow measurement robust to multiphase conditions that are seen in drilling mud, specifically solids and entrained gas. Ultrasonic meters, by contrast, use time-of-flight or Doppler techniques which are less tolerant to multiphase conditions.
Expro’s non-intrusive clamp-on SONAR meters additional benefits include:
- One man rig up
- Non-intrusive design, no wear-parts, maintenance free and rugged, reliable design
- No in situ calibration requirements
- Suited for Oil based and Water based drilling fluids
- High accuracy flow measurement in fluids with high solids content
Wide turn-down to cover all expected flow rates during drilling operations. Changes in fluid properties do not affect measurement performance
- Location on high pressure discharge side of pump; can be mounted on the standpipe, conserving rig floor space and eliminating the need for a flow meter on the suction side of each mud pump.
- ATEX./IECEX Zone 1 and US/Canada Class1/Div2 rated for rig floor operations
- Compatible with industry standard mud logging systems
