This course will introduce the participants to oil and gas exploration by providing an
understanding of the fundamental principles of today’s petroleum exploration
developed from the early important breakthroughs in technology to 3-D seismic.
The course is geared for the practical explorationist, the analyst, or the layman.
Using samples of maps, seismic sections, wells, geochemistry cores and cuttings, the participants will be able to develop an understanding of how exploration companies assess a particular region. The presenter will use examples from both the offshore and onshore basins of North America, North Sea, South East Asia and Australasia.
Comparisons will be made between Australasian basins and other basins in the world and will show how the Australasian basins are generally under-explored.
A state-of-the-art account of the major petroleum plays will utilise key site-specific reconstructions of basin evolution with an emphasis on
- Reservoir geometry and quality
- Seals
- Source rock and migration
- Traps and structural integrity.
The economics of each play will be reviewed and predictions made concerning its future development.
The following basins will be discussed:
- Selected onshore basins of the USA and Canada.
- Gulf of Mexico.
- North Sea.
- The Northwest Shelf Province, including its extension into Papua Guinea.
- The offshore southern margins of Australia including the Great Australian Bight Otway, Bass and Gippsland Basins and their extension into the Taranaki Basin in New Zealand.
- The onshore and offshore Perth Basin, Surat, Eromanga, Cooper, Pedirka, Canning and Amadeus Basins.
- Some selected Basins in the Southeast Asia-Pacific region.
By using sets of examples from different basins, and in different geological and economic settings, the course teaches the participants how to:-
- Make a preliminary assessment of a basin using key wells, seismic lines and other general geological information (a basin analysis).
- Prepare a basic exploration program to explore and develop the basin.
- Make a risk profile based on the risk analysis of:
- Source
- Seal
- Reservoir
- Trap
- Economic setting.
- After a series of fields have been discovered, plan future exploration of the region by assessing the risk analysis (above) in conjunction with a predicted oil and gas trend analysis within an economic framework.
Because sediments are laid within predictable natural systems, such as coastal plains, deltas, and reefs, the participants will learn how comparisons to these modern examples can help the explorer make trend predictions.
It is stressed that the course objective is to create confidence in the participants' ability to understand the nature of the search for oil and gas no matter what their background.
