Objectives
Objective of the Courses:
Primary objectives of the courses are to acquire the basic geology and petroleum geology vocabulary and general concepts. The Courses are designed to teach key terms and concepts that are essential to the oil and gas industry. Topics include: Earth structure, Plate tectonics, Mineral, Rocks and Rocks dating, Tectonic, Sedimentary basins and Sedimentary processes, Exploration applied methodology, Petroleum system assessment, Petroleum formation migration and accumulation.
What you will learn?
At the completion of the courses you will know:
* Fundamentals basic Geology for petroleum engineers
* About different exploration strategies
* About petroleum system and petroleum system assessment
* About source rocks, petroleum reservoirs, Seal rocks and traps and hydrocarbon migration
* The distribution of porosity and permeability in clastic and carbonate reservoirs
* Conventional vs unconventional resources
At the completion of the fieldwork you will know:
* Fundamentals on contour maps and how to use them on the field
* How to collect data (strike, dip and thickness), measure sections, draw up interpretative cross sections and reconstruct comprehensive models of petroleum generation, migration and accumulation.
* How to document the major elements of a petroleum system: source rocks, reservoir rocks, seal rocks and overburden rocks, in relation to their specific depositional environments
* The major functioning petroleum systems in Tunisia
