A new technique for assessing and capturing uncertainty in Previous HitfaultNext Hit seal analysis of hydrocarbon reservoirs is presented. This allows for the rapid evaluation and modeling of uncertainty for cross-Previous HitfaultNext Hit fluid flow (e.g. via transmissibility multipliers). By utilising the Previous HitfaultNext Hit property visualisation techniques presented, only a small number of scenarios need to be taken through to full reservoir flow simulation.


The natural variability of the input data and limited availability of local datasets often leads to the introduction of uncertain values or properties into Previous HitfaultNext Hit seal workflows. The effect of these uncertainties on the results of a Previous HitfaultNext Hit seal analysis is integral to the workflow presented here.


Measured Previous HitfaultNext Hit rock property values from core samples are used to calibrate Previous HitfaultNext Hit rock clay mixing/smearing and Previous HitfaultNext Hit permeability predictors under for application to structural and stratigraphic models. Inaccuracies and uncertainties in both the input data and Previous HitfaultNext Hit property prediction algorithms are incorporated. The ranking of probabilistic scenarios allows an improved understanding of the likely impact of reservoir cross-Previous HitfaultNext Hit fluid flow, whilst at the same time allowing assessment of possible risk factors.


The fluid flow characteristics are assessed in terms of the Previous HitfaultNext Hit hydraulic resistance and the effective cross-Previous HitfaultNext Hit transmissibility (incorporating host cell properties). The impact of these different cross-Previous HitfaultTop fluid flow property distributions are presented by using streamlines. This visualisation technique allows for the rapid comparison of meaningful properties that can be compared across multiple uncertainty realisation models.


The rapid evaluation of multiple uncertainty realisation models means only the most appropriate, fully risked models need to be passed through to a full flow simulation.
