We have developed a specific workflow to evaluate prospects in gas/oil shale exploration which integrates Rock-Eval data, TOC log interpretation, basin modeling and prospect evaluation using a single working platform (OpenFlow Suite). This workflow is based on a combination of modified classical approaches and recent or newly developed ones. These new and modified approaches are innovative because they focus on what “remains” in the source rocks. Accordingly, Rock-Eval, still a fast tool for source rock evaluation, has now a new experimental protocol which is able to better evaluate the S1 peak. Estimation of organic content (Carbolog) is now available in our well log interpretation software (EasyTrace)). As part of an integrated workflow, all the data and results are easily transferred between the different tools (EasyTrace, TemisFlow) thanks to a transverse data base under OpenFlow Suite. This shared platform makes log interpretation, map construction and numerical modeling (1D, 2D, 3D or Multi1D) easier. Basin simulator has also been improved in order to be more predictive both on the fluids (mobile and adsorbed phases) and on the solid matter which are still present is the source rock, making calibration phases faster and easier. All these developments are making breakthroughs for unconventional source rock evaluation.
