The aim of this work package is to optimise, and fully prepare for, the intercomparison testing programme and consists of the following tasks:
1. Specification and provision of the transfer package and associated certifications and other documents. This will consist of instrumentation and other physical elements that will be deployed alongside each MPFM in turn. The transfer package will include flow pattern observation and visualisation technology.
2. Test matrix and protocols. A test matrix defining the test points, in terms of laboratory flow conditions, for optimally selected permutations of test laboratories and MPFMs will be developed. An agreed set of intercomparison testing protocols (methods) will also be agreed. This will build upon the protocols developed and piloted in the preceding EMPR project ENG58, which will be appropriately amended to ensure compatibility with the enhanced range of test laboratories and MPFMs included in this project.
3. Logistics plan. This will include testing schedules and shipping details. The intercomparison scheduling will be optimised taking account of windows of availability for key experimental assets.
NEL will lead the work package, building on their experience as coordinator of JRP ENG58.
The aim of this work package is to acquire the intercomparison test data, using the agreed transfer packages specified, test matrices, test protocols and logistics plan detailed from WP1.
The organisational aspects of this work package will be led by NEL. However, it should be emphasised that VTT, as independent arbiter, will be responsible for ensuring that agreed protocols are competently followed at all test locations throughout the intercomparison test programme.
Following completion of intercomparison tests at NEL, DNV GL, CMR and Rosen reproducibility testing of the transfer packages, with each designated MPFM, will be carried out at NEL to quantify the reproducibility of the transfer package and provide a check for instrumentation drift.
The aim of this work package is to further develop modelling techniques, building on the progress that was made in the preceding EMRP project EGN58, for significantly improving the metrological characterisation of multiphase flows.
Results anticipated are:
1. Inter-laboratory analysis. An analysis of the inter-laboratory differences will be carried out, including the geometrical variances, as a focus for the modelling work.
2. Small-scale modelling. Results from small-scale experimental modelling will be conducted to better quantify the key inter-laboratory influences, such as those above.
3. CFD simulations. Several CFD simulations will be produced that can be validated against small-scale and full-scale experimental data and, thereby, support data rationalisation in the intercomparison test programme.
4. Full scale experimental research. Using the NEL and DNV GL facilities, further experimental research at full scale will be carried out to both assist the intercomparison data rationalisation directly as well as provide appropriate verification data for CFD modelling.
WP3 will be led by University of Glasgow to ensure the activities relating to small scale experimental modelling, CFD modelling and full-scale experimentation are carried out in a coordinated and complimentary fashion.
The aim of this work package is to analyse and rationalise the intercomparison data from WP2 in a robust way to provide the technical basis for a formal reference network that can provide comparable measurements.
The analysis will compare findings, identify anomalies, deduce their method of investigation and the resolutions achieved. The proven methods from ENG58 will be extended and adapted to cope with a much greater number of test lab variants and metering technologies being deployed in this project.
The outputs of the WP will be used as supporting evidence of comparability in establishing the formal reference laboratory network.
VTT, as independent arbiter, will lead the WP with University of Glasgow, NEL and DNV GL acting as key technical advisors who will adapt and specify the methods of analysis.
The results of this project will impact the oil and gas community that is becoming increasingly reliant on multiphase metrology. It will do so by creating an enlarged, comparable, network of multiphase flow measurement reference facilities. This will provide oil and gas operators and instrumentation developers with a renewed confidence in the testing and reference measurement infrastructure. In turn, this will lead to lower uncertainty of measurement and greater confidence in the deployment of multiphase metering technology.
The work package will support the development of new standards and guidelines for harmonised multiphase testing and uncertainty estimation and to provide input to improve regulations.
Further to this, the project will produce a case study for demonstrating to end users how the outputs of the project could be used to reduce uncertainty and increase end user confidence in the metering technology being evaluated. The partners will work with the end user advisory group to develop a case study that is realistic, to maximise impact.
The project will be managed and coordinated by NEL who will be supported by the project management board consisting of representatives from each partner, including the leaders of each work package.
