Shaly Sands (SS), Laminates (LAM) and Low Resistivity Low Contrast (LRLC) pay reservoirs are and always have been the primary problem with log analysis. This course separates and characterises these three overlapping reservoir types and sets out the data sets and petrophysical integration to best identify and evaluate each reservoir type; accurately. This course steps through a logical process to identify cheap, powerful and commonly available data which is useful to the evaluation. It sets out the essential routine and contingent special logs and core data to arrive at fit-for-purpose results. SS, LAM and LRLC pay reservoirs are defined, delineated and treated separately or together, as each petrophysical method demands. All modern logs including NMR, Dielectric, Spectral GR and image logs are covered, together with established and novel core data integration techniques. Quick look evaluation is included and demonstrated using real-time interactive petrophysics demos. Numerous micro-practicals, videos and open discussion sessions keep this class a memorable learning experience!
