Basic Petroleum Geology

With time oil companies became under increasing pressure from investors to translate discoveries into cash-flow as quickly as possible. In addition, growing the field complexity in many parts of the oil sector has made the principles and basics increasingly difficult to formulate and execute. Therefore, it is of great importance to introduce the professional basic training for different staffs of geology, geophysics and the others who are working in the field of oil and natural gas production. The attendees will feel that they became more professional, and know more about the source rocks and their maturation, migration and accumulation of hydrocarbons, reservoir rocks as well as cap rocks, their properties, occurrences and characterization. Participants will be introduced to all of these concepts as they are applied to the process of coming up with basic concepts of petroleum geology and the petroleum system components. This course will acquaint engineers, geoscientists, and operating personnel with the basic techniques.

Course objectives

By end of the course participants will learn:

The basics of petroleum geology, the importance of oil and what is the petroleum system?
The origin of oil as well as types and classification of rocks.
the porosity and types of rocks and how to use it to differentiate between the different elements of the petroleum system.
Factors controlling porosity and permeability will be also discussed.
The main elements of the petroleum regime including the source, reservoir and cap rocks and how to differentiate between them?
Thermal cracking and rock thermal maturation will be also a core of discussion.
The oil migration ; evidences and types.
The oil exploration, coring and rock sampling for different purposes.
A review of petroleum system, uncertainities in oil exploration and reserve estimation as well as oil recovery.
