Red Eye® Multiphase Metering Systems (REMMS) Method of Separation

Weatherford’s REMMS well testing system can be designed to handle any three-phase flow condition. Three-phase fluid enters the GLCC through a narrow tangential inlet. This forces the liquid and gas to accelerate through the inlet and around the vertical axis of the GLCC, creating a vortex.

This vortex causes the gas to separate from the liquid and due to the large density difference between the gas and liquid phases, the gas migrates quickly to the top of the GLCC and the liquid travels to the bottom.

Flow Metering

Oil and water flow rates are measured using a liquid flowmeter and the Red Eye 2G water-cut meter. A gas flowmeter is used to measure the gas rate and then the two phases can be recombined or transported in separate flow lines. Level inside the GLCC is monitored by using a differential pressure transmitter. Gauge pressure and temperature transmitters are also installed on the separator to measure the process temperature and pressure conditions. Liquid and gas control valves are used to maintain an optimum separation level inside the GLCC. The signals from all these instruments are sent to the REMMS remote terminal unit (RTU) which controls the separation and metering processes and displays the well testing results.

The cyclone effect in the GLCC has some damping capability and when coupled with control valves on the gas and liquid legs, it produces an efficient separation system with a very wide operating range. The result is an engineered system that can handle the whole range of flow regimes from steady state to slug flow.
