1. INTRODUCTIONThe worldwide oil and gas exploration and production global picture
2. PETROLEUM GEOSCIENCES
Petroleum geosciences definitions
Geosciences applications along the E&P process from preliminary basin regional evaluation to production,
through block/lease exploration, prospect definition, appraisal/delineation, development, production, EOR, and site restoration
The geosciences disciplines and jobsGeologists, geophysicists, reservoir engineers, geo-information, other non-geosciences disciplines
Geosciences “tool box”
Techniques, methods and conceptsExamples: introduction to remote sensing, surface seeps, surface geology/field/outcrop analogues, sedimentology, structural geology, organic and inorganic geochemistry, reservoirs modeling, borehole rock and fluids sampling, logging, seismics, petroleum system, prospect evaluation, …
3. EXPLORATION CHALLENGE EXAMPLES (1)
Petroleum basin characteristics
Seismic imaging challenges
Recent technology breakthroughs in seismic acquisition and processing
Application of the plate tectonic concept: an exploration
cruise across the South Atlantic Ocean: from the pre-salt Tupi/Ulla discoveries in Brazil to the Kwanza basin in Angola; from Jubilee basin margin wedge play, in Ghana to Zaedius discovery in French Guiana
3. EXPLORATION CHALLENGE EXAMPLES (2)
Evolution of the exploration plays from the onshore to the deep offshore. Example from the Niger delta or the Angola passive margin
Some new petroleum provinces in the making
Examples:
Back to the old exploration days: drilling surface anticlines in Kurdistan (Iraq)
The East Africa Tertiary rift system
Offshore East Africa
The Arctic exploration challenges
