Abstract

Summary

Should fault rock attribute analysis be wider implemented within Wintershall Dea and if so, under which data conditions should it be recommended to estimate fault seal potential using Shale Gouge Ratio (SGR) and when to compute hydrocarbon column heights? This question has been addressed through a comprehensive and detailed project, evaluating Pre-Drill and Post-Drill data analysis and results, run on existing Wintershall prospects. The pre-post drilling comparison of fault seal analysis results demonstrates that understanding the sedimentology is equally important as understanding the structure. It is important to be aware that uncertainties in the input will directly be reflected in the predictive capabilities of the fault seal analysis. For this reason, the integration of a fault seal analysis results in the prospect assessment needs to be decided in dependency of the quality and completeness of the input data. And as each variation of the prospect, will have an impact on the fault seal prediction, the fault seal analysis needs to be in very close cooperation with the prospect geologist to ensure consistency between the prospect model used for prospect evaluation and the fault seal analysis model.
