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
Sand Problems
• Sand in oil or gas
• Pipe wall erosion
• Damage to production equipment
• Reservoir degradation
• Filter replacement - time and expense
• Solids cleaning
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
There are three different types of Sand
Detectors
• Sand Probe
• Sand Erosion Particle Detector (SEPD)
• Ultra Sonic Sensor
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
Sand Erosion Particle Detector
(SEPD)
Overview
• Patented technology
• Ceion® metal loss for cumulative damage
• Integrated passive acoustic element for
instantaneous sand detection
Embedded CEION® DSP Acoustics
Measures:
• Cumulative metal loss
• Erosion rate
• Instantaneous sand detection
• Sand rate detection (0.01g/s estimated)
• Flow regime indication

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

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
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
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
