Subsurface Facies Analysis

Estimated Time to Complete:

2 hours 40 minutes

(average of 20 minutes per Subtopic)

Reviews basic parameters in defining a facies--lithology, sedimentary structures, paleontology, geometry and associated environments. Discusses information sources, including cores, cuttings, well logs and seismic, and summarizes diagnostic features of major facies. Presents case studies on environmental diagnosis of productive sandstone and carbonate reservoirs.
