The system is a modern version of a traditional 2 phase separator. Standard industry methods for water cut and gas/liquid flow measurement are used. Well testing can be done quickly and accurately. This is due to the small liquid volume and short time required to establish equilibrium. Finite element analysis of well conditions and fluid parameters is performed to optimize the CCM's design. This provides assurance of the product's operational envelope at delivery. An integrated control system has been designed by Phase Dynamics to simplify and improve performance for maximum system reliability. Simple operator commands start, stop and display well test results. There are no extra transmitters, PLC's or PC's required. The CCM can be used as a stand-alone system using the local operator interface, control and display, or remotely using the digital interface via Modbus. The first stage of gas liquid separation has a swirl element to create tangential velocity for separation. This creates a force of more than 50 g's on the 3 phase flow. Unlike other systems, which use a simple nozzle to impart the tangential velocity. The second stage completes the separation of liquids from the gas by using additional swirl elements. This provides for very dry outlet gas. The gas is then recombined with the liquid after the control valves. The separated liquid is routed through a full-range microwave water cut analyzer forming an integral part of the CCM. There are no issues with salinity affecting the measurement because of Phase Dynamics' ability to properly handle salinity based on the measurement physics. Coriolis flow meters for the gas and liquid measurement are used for mass flow and density. Observing the density allows determination of the quality of the overal performance of the system. The user then knows that the measurement uncertainty is minimized. The CCM system has been accepted for fiscal well testing in Alaska. |
