Subsurface mapping is a way to visualize various geologic and hydrologic features in any dimension from a one-dimensional cross section to a 4-D production map. All subsurface map types can be useful, but the key is to know what you are investigating and what map types are most appropriate.This new book introduces different types of geophysical logs and subsurface maps that can be generated from basic well data, and subsurface problems that can be solved using geophysical logs and subsurface maps. “Hands-on” exercises reveal how each map type is generated and what applications they may have. Exercises at the end of each chapter introduce different types of wells and lithologies.
