This year's Petroleum Geology Conference in London included the following item on the agenda:

Peak Oil: Advancing the topical debate over the timing of peak oil & gas

The aim of the Geological Society's Peak Oil evening meeting is to further discuss and debate the timing and impact of Peak Oil & Gas. Have we become so efficient at exploring and producing petroleum resources that we are we already there as Colin Campbell ASPO) would argue? Or will technology solutions and a move to more unconventional deposits save the day as Mike Daly (BP) and Glen Cayley (Shell) would suggest? And let's not forget gas. Malcolm Brown (BG Group) sees a longer future for gas but will the progressive use of gas as a substitute for oil hasten its decline? Lots of questions, but do we really have the answers? Come along to the Geological Society on the evening of Tuesday 15th April and join in the debate. Our four invited speakers will present their case, to be followed by a panel discussion.
