註釋A method of examining hydrocarbon gas and total organic carbon data from drill cuttings has been used to identify potential petroleum source rocks and to indicate the level of thermal diagenesis of the organic matter contained in the sediment. As the mechanical disaggregation of the cuttings and the extraction and analysis of the hydrocarbon gases are both rapid and inexpensive, the analyses can be completed almost concurrently with sample collection. Calculation of the regression equations and correlation coefficient for the least squatres line of a plot of gas concentration against organic carbon content classifies the gaseous hydrocarbons as either epigenetic or syngenetic. Source potential is evaluated from a consideration of the abundance and composition of the total released gas.
