Geology of oil and gas

The subject aims at giving fundamental knowledge for the nature of oil and gas, their origin and occurrences in the subsurface. The basic topics, that course gives answers to are when, where and how the hydrocarbons form, migration pathways from the generative pod and what are the geological conditions for accumulation and preservation of economic fields. “Geology of oil and gas” can be considered also as practical petroleum geology, because it is based on many different geological and geophysical disciplines. A good background in basic chemistry and physics is also desirable.

The introductory provides a short overview of some aspects of petroleum geology to introduce the subject and the problems. The other chapters will then expand the knowledge to give a better background in relevant topics. The main goals and tasks of petroleum geology, its history and relationships to other fundamental, natural and applied sciences are well outlined. Special attention is paid on the oil and gas features as raw materials, which separate them in an independent group among natural resources. Then the accent is put on the variety, composition, properties and importance of oil, gas, condensate, gas hydrate, plastic and solid bitumens. The modern achievements in closely examination of hydrocarbon origin are also presented. The geological conditions for generation, accumulation and preservation of oil and gas are consecutively studied in details. There is a short delineation of oil and gas perspectives and methods of prospecting in Bulgaria
