Abstract: As a known source of commercial oil and gas in the Liaohe depression, the lacustrine Shahejie Shale formation is a target of unconventional petroleum exploration. Characterising hydrocarbon generating and phase behaviour evolution is considered to be an empirical method or a prerequisite in resource evaluation and economic estimation. However, this is poorly understood on the lacustrine Shahejie Shale formation as a candidate for shale oil/gas play. According to kinetics of hydrocarbon generation, in this study the source rock potential and physical properties of generated fluids are analysed. Furthermore, this research provides a case study relating experimental data obtained on samples with modelling results. Samples from different wells that represent a range of maturation levels and lithofacies are discussed in this paper. [Received: April 7, 2017; Accepted: September 9, 2017]
