This project aims to provide summative, qualitative, and quantitative models of heterogeneity for key fine-grained unconventional reservoirs and their applications to exploration and production. The project will focus on the following areas:
- Interpret and re-interpret the outcrop and subsurface data of typical fine-grained unconventional reservoirs to investigate the distribution and trend of rock properties, e.g., lithology, grain size, texture, structures, geochemistry, mineralogy, fractures, mechanical stratigraphy, petrology, petrophysics, pore types, pore structure, pore size distribution, fluid compositions, etc., for different facies of a specific geological setting and between different geological settings.
- Develop a systematic approach to qualitatively describe and quantitatively characterize relationship between different property variables and their heterogeneity patterns in time and space at multi-scales.
- Compare the similarities and differences of the heterogeneity of fine-grained reservoirs deposited in different depositional and tectonic settings from regional scale to micro-scale.
- Study the external and internal controls and mechanisms of heterogeneity from source to sink and basin dynamics perspectives.
- Relate the heterogeneity in different depositional and tectonic settings to well log responses, reservoir quality, hydrocarbon accumulation, and production;
- Build database covering most reservoir properties for typical fine-grained unconventional plays for analog, modeling and simulation.
- Establish predictable models of deposition, facies distribution, stratigraphic architecture, and reservoir properties within sequence stratigraphic framework and suggest the potential play fairways of different fine-grained systems.
