Thermal Regime & Geothermal Potential for Africa

This short course will review the thermal regime of Africa as it affects both geothermal potential and the prediction of source rock maturity.  The principles of heat and temperature in the subsurface are first reviewed before considering the causes of the numerous thermal anomalies around the continent. Geothermal potential in Africa generally relies on temperatures sufficient to generate electricity and therefore on very high geothermal gradients.  We will focus for the practical part of the course on the East African Rift System, where two short interactive exercises will be run in a basin with geothermal potential using data gathered from petroleum exploration. These will demonstrate the techniques applied and the risks inherent in geothermal exploration. Finally we will consider synergies between the geothermal and petroleum exploration industries, including the consideration of hydrothermal systems and the importance of thermal conductivity, both of which are vastly underrated in importance in the evaluation of petroleum systems.



The times below are listed in Central Daylight Time (CDT).

09:15 - 10:00 Exercise 1: Geothermal Gradients

10:00 - 10:15 Break

10:15 - 10:45 Geothermal Potential

10:45 - 11:30 Exercise 2

11:30 - 12:00 Other Regions / Wrap-Up / Discussion


Speaker: Duncan MacGregor

Duncan Macgregor is a former BP geologist, and has consulted for the past 24 years for a number of companies, mainly on African ventures, including much of the East African rift system. He is now a specialist on the regional geology of the African plate (see www.macgeology.co.uk for his latest work on a paleogeographic atlas of the continent). He is also a former technical chair of the PESGB/HGS London conferences and has presented several times. His work on the thermal regime of Africa, referenced below (which is a recommended pre-read), was the most downloaded paper from Journal of African Earth Sciences for that year. He now works part time and still presents a number of Africa-focussed courses. The Geothermal Atlas of Africa currently being compiled includes many contributions from him.
