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

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

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

• 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 gt1.0 m/s,
• particle size gt 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
