Fully Coupled Flow-Deformation Model for a Naturally Fractured Gas Reservoir
The Lacq gas field, a large scale fractured reservoir subjected to a significant depletion in its production life, has been investigated. A fully coupled model - two phase fluid flow in deformable fractured porous media - has been utilised in the investigation. Spatial discretisation of the governing equations has been achieved using the standard Galerkin method while the finite difference technique is employed for the discretisation of the time domain. A three dimensional finite element model representing a quarter of the reservoir and surrounding rock layers has been created and subjected to the actual course of field production from 1957 to 1989. A good agreement has been found between simulation results and field data on reservoir pressure evolution, maximum ground settlement and subsidence profile along the northwest-southeast direction.
