Paper presented at the 8th World Petroleum Congress, June 13–18, 1971
Paper Number: WPC-14107
... While the first scientific theories on the origin of petroleum (Berthelot in 1866; Mendelejeff in 1877) were based on non-biogenic processes, an increasing evidence in favour of the biogenic theory has been accumulated, thanks to the combined contribution of geologists and gewhemists. It is fair...

The results of the theory are then compared to gas production data obtained from a shallow shale reservoir in Western Canada. Production from biogenic shale gas reservoirs tends to be at low rate but is stable over extended periods...

... into the overlying waters. Thus, the detection and characterization of marine seepage may reveal the location of offshore oil and gas deposits. In theory, petroleum-related (petrogenic) gas can be distinguished from microbially-produced (biogenic) gas by the presence of significant quan- tities of ethane-and-higher...

It provides the industry's first predictive asphaltene grading equation of state (EOS) and has proven reliable to predict connectivity in equilibrated oil columns. The theory shows that asphaltene gradients can be large owing to both the gravity term and GOR...
