Subsurface Mapping

This course details indicators of normal and reverse faulting, using faulted and unfaulted well logs. Two common problems with computer-generated contours are discussed. How faulting is indicated on a structural contour map where faulting is contemporaneous with deposition is explained. Isopach maps are defined and their use is described. The differences between isopachs and isochores are explained. How structure maps can help identify deposition, faulting and folding events and timing is explained.

The course discusses isolith maps and how they are useful for reservoir engineers. The purpose of paleo-structure maps is described. How a reservoir’s spill point helps in the understanding of the reservoirs ability to trap and hold hydrocarbon accumulation is detailed. How both timing and trapping mechanisms must work together to achieve hydrocarbon maturation, migration and accumulation is discussed. The five workflow steps that use both structure and isopach maps to define the paleo-structure and post-structural movement are listed.
