3. Why do we need sand detectors?
Early warning of sand production
Identification of individual wells producing sand
Optimising production Monitoring accumulation of sand
Preventing lines filling with sand
Checking integrity of sand screens
Reducing the risk of erosion

4. Sand Problems Sand in oil or gas Pipe wall erosion
Damage to production equipment
Reservoir degradation
Filter replacement - time and expense
Solids cleaning

5. System Solutions
Provides quantitative and qualitative indication of solids production
Optimisation of production rates
Enables damage assessment of pipes & valves
Determination of methods of control

6. There are three different types of Sand Detectors
Sand Probe
Sand Erosion Particle Detector (SEPD)
Ultra Sonic Sensor

7. Sand Probe (Ceion® Sand Erosion Sensor)
Intrusive
Cost Effective
Can be used on straight pipe (Angle Probe)
Accrete readings for Wall Loss of pipe
Real Time or Stand alone

8. Sand Erosion Particle Detector (SEPD)
Overview
Patented technology
Ceion® metal loss for cumulative damage
Integrated passive acoustic element for instantaneous sand detection
Measures:
Cumulative metal loss
Erosion rate
Instantaneous sand detection
Sand rate detection (0.01g/s estimated)
Flow regime indication
Embedded CEION® DSP Acoustics
Acoustic
Erosion
TU-SMP 8 8

9. Embedded CEION® DSP Acoustics
SEPDTM Probe
Other features:
Embedded DSP for real-time frequency analysis.
1MHz sampling speed
Frequency analysis up to 500kHz
FFT completed every ms and averaged 1000 times. (i.e. result every 1s)
Configurable band pass filtering
Configurable gain amplification
High S-N ratio
Embedded CEION® DSP Acoustics
TU-SMP 9 9

10. SAM 400 SAM 400 SAM 400 TC Passive acoustic transducer technology
Measures sand production in oil, gas or multiphase wells
Compact and ultra sensitive
Detects smaller particles at lower flow velocities than competitors
Non-intrusive

11. Measurement principle (ultra sonic)
The detector is installed down stream of a 90° bend
Sand impacts the inner pipe wall
Detection Limits:
Velocity >1.0 m/s,
particle size > 15 m

12. RSI-650 Sand Injector
The injector will inject a calibrated amount of sand into the stream at a current velocity for a set time.
Up stream of Roxar Sand Sensor.
With a Analogue or a digital barrier we can hook up to the PLC
