... in 1D (wells), which is a function of porosity (PHIT), total organic content (TOC), oil saturation (S O ) and volume of clay (v cl ). The resultant calibration is applied to the seismic volume using inputs from deterministic inversion to predict most probable oil-prone facies. Generally, areas with high...

With the matrix density derived from spectroscopy measurements, the porosity calculated has a difference compared with the NMR porosity, which confirms the existence of the bitumen in the reservoir. Bitumen and oil volume were evaluated based on the method...

... of PNL include: (1) Neutron porosity, which can be used to calculate formation porosity together with compressional slowness from DSL. (2) Capture and inelastic elemental spectroscopy, which were utilized to obtain accurate mineralogy and in-situ total organic carbon in shale. (3) Thermal neutron capture...

By conducting imbibition and nuclear magnetic resonance experiments on saturated cores, the imbibition degree of the oil phase is analyzed under varying imbibition time and porosity for different pore throat radii. A model for oil phase saturation distribution is developed considering...
