Client: Confidential Location: Onshore Brazil Optimising gas production ‘gas field-well-network’ systemXodus provides integration of multiple gas fields, wells and network elements to optimise dynamic interactions of a complete petroleum engineering system. ChallengeThe operator was seeking expertise for production strategy and field development plans to achieve long term gas contract volume flexibility. A decline in Non-Associated Gas (NAG) and uncertainty over historical data called for rigorous sensitivity analysis. Gas contract requirements drove an aggressive timeline for new fields becoming available for fast-track development. Assignment scopeXodus provided a highly qualified professional who worked with the client to: Review and evaluate available data, resources, organisation and skill sets Provide data acquisition plans for field shutdown, production optimisation and wells Revise static and dynamic models by history matching and well modelling ResultsSuccessful implementation of optimised data acquisition programmes for all wells Effective co-ordination with the production team resulted in a field shutdown of just a few days and a cost saving of millions Dynamic modelling of existing field identified a region of undrained gas that was found to contain in excess of 40 Billion cubic feet (Bcf) of gas at the original reservoir pressure Creation and evaluation of multiple development scenarios successfully extended the production plateau and deferred the start of compression Compression mimicked by using pressure constraints Model results used to feed data to detailed design and engineering, and pipeline size requirements provided to procurement team for fast-track development plans.
