Geologic,geophysical,and petrophysical interpretation of core data and well logs

摘要

Modern reservoir characterization requires close integration of multidiscipline and multiscale subsurface data, including core measurements, well logs, seismic surveys, and production curves. Core measurements and well logs are on the small end of the data spectrum, and they provide indispensible high-resolution information for validating and calibrating geologic models. Integration of core data and well logs into reservoir description workflows is particularly important for deepwater subsalt or presalt reservoirs and mature onshore fields with complex production history. Meanwhile, the emerging unconventional resources pose additional technical challenges in interpreting core data and well logs due to their different storage and flow mechanisms. The best interpretation practices maximize the values of core data and well logs by extracting all relevant geologic, geophysical, and petrophysical attributes to interface with seismic and engineering data for constructing verifiable reservoir models.
