Developing "Super Basins" is probably a good way to continue providing oil and gas production with is low carbon intensity and low cost. We'll continue our series of webinars on this topic a week on Oct 22, with a talk from John Dolson, Adjunct Professor at the University of Miami, Florida and consultant with Cairn Energy India. He has his own consultancy, DSP Geosciences.
Mr Dolson is a geologist with 40 years experience, including 28 years with Amoco/BP. He is a former VP of the American Association of Petroleum Geologists (AAPG), and author of a book "Understanding Oil and Gas Shows and Seals in the Search for Hydrocarbons" (Springer, 2016).
The talk will review the update of the AAPG's Giant Fields database, with a Giant Field defined as being greater than 500 mmbo equivalent. This is the first update in 20 years. It shows some paradigm shifts which have occurred in petroleum geology over this period into what it takes to find a new super basin.
Mr Dolson will end with geological questions which may need more thought, such as factors allowing drilling at greater than 10km, why many giant fields are over oceanic or greatly thinned continental crust, possible hydrodynamic modifications in such over pressured settings, concerns about upward basin hydrodynamic flow, which could completely flush prospective traps.
One approach is took look at the deepest petroleum systems and oldest basins underlying proven, shallower hydrocarbon bearing systems.
Geochemical finger-printing, deep seismic imaging and tools like Fluid Inclusion Stratigraphy may unlock new concepts on the deepest and least explored parts of proven basins.
The tectono-stratigraphic history of many, if not most, onshore basins is complex, and in many basins older Paleozoic, Neoproterozoic terranes, or deeper rift systems underlie shallower Mesozoic and Cenozoic plays, and offer untapped potential.
