Along with the Research Institute of Petroleum Exploration and Development at PetroChina, the National Energy Tight Oil and Gas R&D Centre in China and the College of Earth Science at Jilin University, DigiM conducted a study of Petrophysical Properties Using Nano-Scale Resolution Electron Microscopy and 3D to 2D Upscaling.


High resolution microscopic imaging is an indispensable 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 the Chang-7 member of Ordos Basin, Northwest China, both high resolution focused ion beam—scanning electron microscopy (FIB-SEM) 3D imaging and 2D large field of view SEM imaging were used as inputs for our multi-scale numerical modeling framework. The predicted 3D rock physical properties from FIB-SEM at nanometer pore-scale were 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 scales were computed with nano-scale properties factored in. The systematic upscaling approach allowed us to investigate the high potential shale oil play in the prospected area in an unprecedented timely and economic manner.
