3 Sand production trending Finding Maximum Sand Free Rate (MSFR). Quantitative Measurement Requires input of flow data / flow speed How much sand are you producing Finding Maximum Acceptable Sand Rate (MASR). Quantifying the Signal The particles are quantified by applying the measured ultrasound signal and flow information to an algorithm. Quantifying the Signal Kinetic Energy = Mass * Velocity2. (Raw Value-Zero) = Sand Rate * Step Sand Rate = (Raw Value-Zero) / Step Raw Value = sensor Output (Acoustic Energy). Zero = Sand Free Raw Value Step = Calibration Factor related to velocity Alarming Average sand rate Average sand rate 58 Average sand rate 45. 3 slugs, 1 lb each lbs/day Amplitude lbs/day Amplitude = lbs/day Amplitude =.

4 Sand rate: Sand rate alarms may be based on erosion models, but should include delays to minimize nuisance alarms. Mass: Mass alarms focus on the quantity of sand produced rater than the real time sand measurement.

Next generation technology, available today. DSPII capabilities include: Increased processing power Increased memory capacity Simultaneous measurements, sand, flow, vibration Capable of running complex algorithms internally DSPII Internal Processing DSPII processing allows the sand calculation to be performed internally by the sensor . Configuration and calibration and real time calculated data is available over the Modbus protocol.

5 SandQ Benefits The SandQ Monitor will provide flow information/data directly from the FlowQ . The SandQ Monitor will recognize/detect well flowing changes The SandQ Monitor will detect particles simultaneously with the FlowQ . The SandQ system can be implemented in the existing clampon DSP-06 already installed system with a small Plug-In module in the software to give it upgraded capabilities (DSPII).
