Unconventional reservoirs frequently have nano-darcy permeabilities, complex fracture networks from natural or induced fractures, and adsorbed gas in organic materials in the rock matrix. Using the ECLIPSE Coal and Shale gas option, the complex physics associated with these phenomena can be modeled and understood.
- Dual porosity model consisting of two interconnected systems representing the rock matrix and the permeable rock fractures.
- Multiporosity model that enables detailed study of transient behavior in the matrix.
- Adsorption and diffusion based on Langmuir isotherms, including the option to model time-dependent diffusion.
- Incorporates rock compaction effect.
