Petroleum development geology is a hybrid discipline. The concepts are important for exploration geologists as well as development geologists. The book overlaps the following disciplines: structured geology, stratigraphy-sedimentation, reservoir engineering, drilling engineering, well log-analysis, reflection seismology, petroleum land manager, economics and organic chemistry.
