The Centre for Enhanced Hydrocarbon Recovery and CO2 Solutions (formerly the Hydrocarbon Recovery Mechanisms project) has been investigating various hydrocarbon recovery mechanisms to improve the current understanding of the pertinent processes and produce information required for the efficient planning and management of field production. Unique laboratory core test facilities, high pressure flow visualisation in micromodels, mechanistic and numerical modelling of flow through porous media are used to achieve research objectives.
High pressure flow visualisation at the pore level is performed in three high pressure micromodel rigs resulting in more understanding of the reservoir processes as well as quantitative information. Four core test facilities operating at simulated reservoir conditions, including X-ray local saturation measurement capabilties, are used to produce field specific and generic data. Mechanistic and numerical modelling of flow through porous media, based on in-house experimental observation and measurements, are conducted to generalise research results.
The research programs, which are based on the view of project sponsors, are prepared and successfully conducted using the available unique facilities helping both theoretical and experimental teams of expertise.
The research areas include flow of gas-condensate near the wellbore, well deliverability improvement, trapping of hydrocarbon by water and its subsequent remobilisation by depressurisation, water alternating gas (WAG) injection, miscible WAG and simultaneous injection of water and gas (SWAG) and recovery from naturally fractured reservoirs.
