ABERDEEN, UK – Emerson Process Management has launched its new downhole flow sensor system. The new system will, for the first time, generate multiphase flow measurements from downhole in the well leading to increased operator understanding of reservoir flow and zonal contributions from wells and increased production control and optimization.
Key features of the Roxar Downhole Flow Sensor System include:
• Accurate and reliable flow rates. The technology is built on the Zector platform of Emerson’s third generation multiphase meter with new field electronics, electrode arrangements and improved measurement models. The flow sensor system includes a new water cut measurement tool based on dual velocity measurements and a density sensor, measuring the density of the fluid using gamma rays. The system can operate at pressures and temperatures of up to 10,000 psi and 150ºC respectively.
• A compact and easy to use solution. The 3.5” tool and ¼” cable is compact and easy to install, fitting in both short zones between packers and in 7” liner/casing. There is a single conductor for all well sensors including the downhole gauges and the system can be fitted to existing subsea control systems without the need for modifications. Measurements are performed in the tubing through non-intrusive sensors.
• The flow sensor system is also highly flexible and forms part of a broader downhole solution. The system is modular with users able to pick the tool combination which best suits their needs - water cut only, for example, and is fully compatible with the Roxar downhole product portfolio, which includes high pressure and high temperature gauges. The flow sensor system is also fully integrated with Emerson’s production management system, Roxar Fieldwatch, providing production and reservoir engineers with the tools and data to make better informed reservoir management decisions.
