Fundamentals of Production Geology.
ABOUT THE COURSE:
OThe objective of the course is to transmit the basic concepts of Geology used in the oil industry to personnel whose original formation does not include Geology. It begins with a summary of the theories that, on a mega scale, have tried to explain the Earth origin and formation, and the processes that influence the formation of reservoirs. Then we proceed to define and detail those branches of Geology that govern the generation and characteristics of the reservoirs: the structural component and its influence on traps, definition of the different structural processes and their results, types of traps, etc.; sedimentology and stratigraphy in the reservoir geometry, genesis of the rocks and the minerals that compose it, importance of elements such as clay distribution, pore geometry, destructive and constructive effects of the diagenesis on the reservoirs, etc. Petrophysics to define the properties of the rock and its flow and storage capacity, definition of porosity, permeability and fluid saturations; the geochemistry to show the reservoirs fluid migration and the laws that regulate this process such as flotation pressure, hydrocarbon composition, etc. Finally, the integration of all of them to define the reservoir; tops, thicknesses, rock quality, fluid contacts to conclude with a model and applications from the economic point of view: reserves, development plan, definition of opportunities.
The course has a high component of graphic examples that illustrate the topics and help the transmission of knowledge.
