SA IAH/NCGRT Modellers’ Forum #5

The GEN3 Surat Basin Regional Groundwater Flow Model will be introduced and discussed.



The GEN3 Surat Basin Regional Groundwater Flow Model is the third numerical groundwater flow model to be generated for the QCLNG Project. The model integrates a robust and regionally-consistent stratigraphic framework of the major geological units with the latest hydrogeological conceptualisation of the Surat Basin. The key enhancements compared to previous simulations are the detailed characterisation of the Walloon Subgroup and dual phase gas and water modelling capability. This regional groundwater flow model will be the first time to our knowledge that a model of this scale has been built for groundwater impact assessment with the petroleum industry standard simulator: ECLIPSE. Use of the ECLIPSE software, with its dual phase, porosity and permeability functionality, has allowed cross disciplinary collaboration and innovative hybrid workflows to quantify the drawdown associated with QGC’s coal seam de-pressurisation


Daniel de Verteuil BSc MEng ARSM has overall responsibility for the construction of the GEN3 model. He is a geologist with a masters in petroleum engineering. He has 16 years’ experience as a reservoir engineer modelling and simulating the subsurface for over $6 billion of oil & gas developments on 5 continents, which includes a focus on environmental issues such as CO2 sequestration and waste water disposal.

Patrick McKelvey BSc MSc CGeol is the Groundwater Manager for QGC with  responsibility for water resources management. He is a geology graduate with a masters in hydrogeology. He has 22 years’ experience in groundwater and water resources management for natural resources projects, international development, water supply and environmental engineering.

Rhodri Vaughan BSc MSc MEng is a reservoir engineer with 7 years’ experience in reservoir simulation in oil and gas projects. He has particular expertise in dual phase modelling in conventional and unconventional hydrocarbon systems.
