Abstract

Summary

OMV New Zealand gas/condensate fields’ gas production is limited by commercial demand, which also constrain production of associated condensate. No test separators nor individual well multiphase flow meters are installed, only single-phase gas flow meters (V-cones flow meters and orifice plate) for each individual well. In order to produce the maximum revenue for the fields, the wells with the highest condensate-gas-ratio need to be prioritized, while still ensuring that well and facilities constraints are managed.

An agile crew of engineers, developers and data scientists, have been mobilized to design and create reliable, easy to use and easy to maintain software solutions to solve three different parts of the optimization problem: A live, dynamic visualization of the wells operating envelopes for dynamic monitoring of the current status of individual wells versus the constraints and direct comparison with simulation models results. A software solution to automatically identify step-changes in well gas, water and condensate rates at facility output level, using these changes to improve CGR and WGR allocated value for each individual well. A software application to calculate the best combination of individual well rates to meet gas export demand while maximizing condensate production, within facility limits and well operating envelopes.
