This self-directed course covers visual and numerical log analysis methods for a wide spectrum of unconventional and unusual reservoir types. A case-specific petrophysical model for each unconventional reservoir is provided, including spreadsheet models for most calculations. Total organic carbon (TOC),coal bed methane (CBM), gas and oil shales, tight gas and oil, bitumen bearing oil sands, laminated sands, low resistivity pay, igmeous and metamorphic rocks, gas hydrates, geothernal wells, evaporites .... more to come as time pernits.
