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 ProblemsSand Problems

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

System SolutionsSystem 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 There are three different types of Sand DetectorsDetectors

• Sand Probe

• Sand Erosion Particle Detector (SEPD)

• Ultra Sonic SensorUltra Sonic Sensor

Sand Probe (Sand Probe (Ceion® Sand Erosion Sensor)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

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

9TU-SMP

• 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)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
