Abstract
Evaluation of source rock potential using well log data alone, e.g. density or sonic log, is limited to the assessment of total organic carbon (TOC) content. Well logs that directly measure the most important source quality parameter, the hydrogen content of the kerogen, do not exist. Therefore, a method is proposed that combines log-derived TOC data with calibration schemes relating TOC content to Hydrogen Index and maturity for individual source rock sets. The method has been applied to the compositionally heterogeneous Kimmeridge Clay Formation of the North Sea and the homogeneous Lower Toarcian Shale of N.-Germany. The combination of well log and geochemical data greatly improves the accuracy with which the lateral and vertical distribution of source rocks and their potential can be predicted on a basin and prospect level.
