resolution microscopic imaging is a tool for unconventional
resource prospecting, exploration and production, due to the nano-scale
hydrocarbon storage units and their complexity. However, balancing the appropriate
high resolution detail with a representative, large-enough field of view has
always been a challenge. Focusing on Chang-7 member of Ordos basin, Northwest
China, we use both FIB-SEM and a 2D large field of view SEM imaging as
inputs to our multi-scale numerical modeling framework. The predicted 3D rock
physical properties from FIB-SEM at nanometer pore-scale are integrated with
laboratory measurement data on mineralogy and geochemistry to enable direct
numerical simulation of petrophysical properties on 2D SEM images. The
corresponding properties at larger and facies-representative scale are computed
with nano-scale properties factored in. The systematic upscaling approach allows
us to investigate the high potential shale oil play in the prospected area in
an unprecedented timely and economic manner.
