Production Separators

Sand Separation in Produced Water

FLUXUS® WAGs its tail WAG (Water-Alternating-Gas) injection can boost oil recovery from reservoirs, but sometimes at the cost of increased sand production.

One major Norwegian oil company faced with this problem installed Online Vessel Desanders (OVDs) to remove sand from the separator vessels.

To operate the OVDs correctly, the company needed to measure produced water in 50.8 mm (2 inch) pipes on the inlet and outlet of each unit.

The answer was the FLUXUS® ADM8127 ultrasonic flow measurement system, which can withstand rough and hazardous offshore environments.

Because of the tremendous success of the system, the company bought 16 dual-channel units with 32 hazardous area certified transducer pairs to monitor the OVD units.

FLUXUS® overcame the following challenges:

Sand erosion of insertion meters
Space and weight constraints
Accurate measurement of multiphasewater/sand mix
