Basic Seismic Interpretation

Course ID: t38736

Introduces seismic data interpretation. Lists the four basic steps in structural seismic interpretation. Identifies where to pick the horizon on the seismic waveform and why. Explains why migration changes the reflection times on dip lines, but does not change them on strike lines. Recognizes the location of favorable traps for hydrocarbon accumulations. Explains the timing and the depositional mechanics of faulting and how this impacts oil and gas migration. States the different types of seismic effects that can be misleading during interpretation. Explains the concept of sequences; intervals within which the sediments are genetically related. Describes how the amplitude, polarity, and shape of the seismic signal are important to understanding the geological lateral variations of the subsurface. Differentiates between bright spots, flat spots and dim spots on seismic sections, and explains what causes these direct hydrocarbon indicators. Outlines how crosswell seismology provides high density, depth-calibrated seismic data between two wellbores. Describes how and where seismic attributes are applied.
