Abstract:In coal seam methane reservoirs, the pre-existing natural fracture network and in-situ stress state are key parameters controlling productivity. A large degree of production variability can result from the interaction of a highly deviatoric stress tensor with the pre-existing fracture network. This effect can be qualified by stress framework and restorative modelling. However, the next step is further quantifying the geomechanical analyses using data from production and hydraulic fracturing treatments.
We use the Baralaba Coal measures as an example to illustrate how a more thorough understanding of this important reservoir parameter can aid hydraulic fracturing treatment design and reservoir developmental planning. We will demonstrate how this data can be used to improve a CSM field development plan.
