Abstract:

Eleven petroleum source rock samples have been examined by Emission Fourier transform infrared spectroscopy FTIRES.and by Rock-Eval thermal analyses. FTIRES has been used to estimate the amount of C H aliphatic and C H aromatic signal lost during thermal treatment at Rock-Eval temperatures. In particular, the loss of signal from 1508C to 3008C has been monitored and compared to the yield of oil obtained over this range by Rock-Eval analysis. Likewise, signal loss between 300 5008C and 500 7008C was monitored. Correlations of FTIRES changes with Rock-Eval pyrolysis derived parameters were not found because FTIRES reflects changes in composition of undistilled material during pyrolysis. However, by relating Rock-Eval and FTIRES derived parameters a source rock quality index can be derived. This index can be useful as a quick routine method for scanning samples to determine if the free oil in the source rock was generated by thermal maturation of the same source rock.
