REMMS Metering System
The Red Eye® multiphase metering system (REMMS), combines partial separation technology with conventional liquid and gas metering to provide a complete multiphase measurement solution. An advanced controller governs the operation of the system as well as interpreting and recording data and providing communications with external host systems. The REMMS unit can be used for automated well testing at a manifold or on an individual well.
The main components of these multiphase metering systems are a gas-liquid cylindrical cyclone (GLCC) separator, flow metering instruments, and level control valves. The principle of operation is based on inducing bulk separation of the liquid and gas phases by creating a cyclonic flow pattern. Once separated, individual streams are measured with conventional liquid and gas meters. The separated phases are then recombined or transported in separate flowlines. Although this concept and its advantages have been known for some years, recent advances in technology have brought GLCC separators to the forefront of multiphase metering in the oil and gas industry.
Weatherford’s REMMS well testing systems are built to ANSI B31.3 piping code. This provides greater flexibility for designing and building systems to handle any well head or process pressure and temperatures up to 450°F (232°C). It also eliminates the need for a pressure safety valve on the system. Depending on customer requirements, production well testing systems can also be built under ASME Section VIII, Division 1 vessel code specifications.

REMMS Metering System Applications
- Production testing - REMMS replaces conventional two- and three-phase test separators with an automated system incorporating higher capacity and efficiency per footprint and weight. Due to the short residence time in the REMMS separator, well test time may be shortened, enabling the operator to have the latest well performance data. Turn-down ratios from 40:1 with single meters and up to 100:1 with multiple meters can be achieved.
- Individual well monitoring - Weatherford continuous well testing systems can also be used to monitor individual wells. The data can then be used to optimize gas-lift, water, or steam-flood injection rates, or any artificial-lift system. Most importantly, the continuous data can be used to optimize the yield from the entire reservoir, maximizing the company’s return on its investment. When REMMS is installed at each wellhead, the operator has real-time production data, which can be used to provide more accurate statements of production, allocation, and payment of petroleum royalties. Networking the wells offers a tremendous savings in piping costs and instrumentation.
- Client-specific requirements - Weatherford’s units are built per client specifications. They can be designed to meet client expectations in terms of size, metering options, accuracy, redundancy and integration with other existing equipment such as choke valves or MPSVs. REMMS’ mechanical design can be modified if there are any space constraints, and the operating software can be customized to add inputs from any additional instruments that might be required to provide a successful well-testing solution for a particular application.
