Multiphase

Achieve flexibility and accurate flow rate measurements in the most challenging fields

Multiphase Metering Principles

Operators today are looking for flexible, scalable and accurate multiphase meters that meet field requirements, yet also provide value for money in the most challenging of fields. Through developments in signal processing and field electronics alongside a modular approach, multiphase meters are rising to the challenge, delivering increased flow assurance and production optimization and meeting all field and cost requirements.

How It Works

Direct and continuous multiphase flow monitoring at the wellhead ensures greater measurement accuracy and eliminates the need for dedicated test lines and test separators.

The Multiphase and Wetgas meters apply a combination of electrical impedance measurements with cross correlation for velocity measurements. Depending on the application and measurement needs, the system can be extended with Venturi measurements, a gamma density system, a sand monitoring system, salinity measurements and a Wetgas operating mode.

Operators that use multiphase meters to monitor their wells will obtain real-time and continuous well flow information. This will allow for early detection of water/gas breakthrough and improved well control. Knowledge of the individual phase flow rates of a producing well are required to facilitate reservoir management, field development, operational control, flow assurance and production allocation.

With instantaneous flow rates, operators can make real-time decisions on their well’s production capabilities and determine the volumes of each phase produced and monitor critical events like water and gas break through.

The cost of separators can vary considerable depending on the sophistication of the solution, philosophy, geographical location, application and use. Multiphase meters potentially allow for significant CAPEX and OPEX savings in many examples compared to traditional solutions. By using a multiphase meter, there is often no need for the test separator, test manifold and test line. Each well can be monitored continuously without having to redirect them through a test line or use a mobile well test separator.

Applications

Accurate measurements in flowback operations, and initial, mid-and late life production in the North American shale industry. By adopting well-pad designs that are using one Roxar 2600 Multiphase Flow Meter per well instead of separators, operators achieve accurate well allocation measurements, as well as reduced well pad footprint and reduced pipe line costs.

Shale Oil

Mobile Well testing with Roxar 2600 Multiphase meters installed in trucks or fixed well testing installations is a common application. The Multiphase meter is supported by Fieldwatch software that enable post processing of measurement data to allow for well testing without complete PVT data available at the time of testing the well. Optimizing the workflow and saving costs&time in the field for the well testing company.

Real time well testing

For assessing the optimal production strategy, for monitoring water production or GOR trends, the Roxar MPFM offers direct and continuous data from the well enabling production optimization and flow assurance strategies to be perfected.

Reservoir monitoring

Reservoir Management & Production Optimization

On offshore- and often unmanned wellhead platforms direct and continuous well monitoring is crucial and space and power resources are limited. The Roxar 2600 MPFM is ideal to be used under such circumstances. With 100% remote operations, no moving parts and low power consumption, compact size, the Roxar 2600 MPFM is the field proven Multiphase metering solution to be used for wellhead platforms

Unmanned Wellheads

One Multiphase meter per well is finally possible for onshore low producing wells. The MPFM 2600 modular design enables a simple cost efficient well monitoring set up. This one meter per well strategy saves pipelines, manifolds, test separator costs and in addition provides real time well measurement data to monitor production. The Roxar 2600 MPFM comes with easy set up wizards and remote connectivity to minimize operators to spend time in the field.
