The Philosophical Doctrine of Accurate The Philosophical Doctrine of Accurate Subsurface Interpretation and Mapping Subsurface Interpretation and Mapping The object of this class is to give you the basic principles of describing the subsurface with limited remote sensing information And to introduce you to new computer oriented techniques for visualizing and analyzing this subsurface data. We will use the 10 key points of (Teapock and Bischke, 2006) philosophy of subsurface interpretation as the bases for this class. Brown, Nunn, and OSears, 08

10 Key Aspects of Accurate 10 Key Aspects of Accurate Subsurface Interpretation and Mapping Subsurface Interpretation and Mapping 1. All subsurface interpretations must be geologically and geometrically valid in three dimensions. 2. An interpreter must have a fundamental, classic education in geology and a strong background in structural geology for the tectonic setting being worked. 3. Sufficient planning, time and detail are required to generate reliable prospects. Haste makes waste. Brown, Nunn, and OSears, 08

10 Key Aspects-Cont’ 10 Key Aspects-Cont’ 1. All subsurface data must be used to develop a reasonable and accurate subsurface interpretation. 2. Accurate correlations (well log and seismic) are required for reliable geologic interpretations. 3. The use of correct mapping techniques and methods is essential to generate reasonable and correct subsurface interpretations. Brown, Nunn, and OSears, 08

10 Key Aspects-Cont’ 10 Key Aspects-Cont’ 1. All important and relevant geologic surfaces must be mapped and the maps integrated to arrive at a reasonable and accurate subsurface picture. 2. The mapping of multiple horizons is essential to develop reasonably correct, three-dimensional interpretations of complexly faulted areas.
