Global Warming and Evolving Petroleum Reservoir System
Temperature being one of the critical factors in the generation of hydrocarbons in a source rock (which has already attained a minimum level of maturity), whether, the current apprehension on ‘enhanced mean global temperature’ would actually lead to an ‘enhanced action of heat’ on the organic matter (kerogen) contained in the source rock (clay/carbonate organic-rich muds deposited under low-energy, anoxic conditions) sediments, which would in turn, possibly, lead to an ‘enhanced formation of oil and gas’?
So, more and more, permeable petroleum reservoir rocks will be in communication with the matured source beds (as time progresses) as per the current apprehension?
Since, trap formation must predate hydrocarbon migration, can we also expect that there will be a growing formation of Structural traps (enhanced changes in the shape of the reservoir); and/or, Stratigraphic traps (enhanced variations in lateral continuity); and/or, a combination trap, while @ the larger-scale, are we, also, currently experiencing an enhanced thinning and stretching of the lithosphere caused by an enhanced upwelling of the underlying asthenosphere – resulting from the 'enhanced mean global temperature'?
With cities like New York and Jakarta experiencing a significant differential subsidence as of now, will they become an ideal candidate for great (petroleum) sedimentary basins (with an enhanced dynamic depocentre) in the future (in geological time-scales)?
Are we currently experiencing an enhanced deposition of finer-grained sediments resulting from transgression (relative rise in sea level)?

The question is : where the nutrients come from ? I'm working on paleogegraphy and palaeoenvironnement of London Brabant massif and Wessex (Kimmeridge clay) / paris basin (Boulonnais aera).
