Summary:
Conventional well test interpretation is based on employing simplified analytical models for parameter estimation. However, an enhanced use of the well test data for the reservoir characterization is only attained using geological well testing. Geological well testing is used to validate the dynamic response of the model using available pressure transient tests. This paper presents a novel visual steering framework for dynamic validation of the reservoir models using the well test data. The software has the ability of correlating the 3D models with the well test diagnostic curves for detecting the influence of the reservoir and fluid heterogeneities on the transient behavior of the model. The engineer is able to update the geological model using various facilities embedded in the software using manual and/or assisted history matching approaches. We show a challenging well test response in a faulted channelized environment in a gas condensate reservoir and present a sensitivity study to understand and interpret such a complicated well test response using our developed framework. This work is aimed at designing a multi-source, multi-domain framework for efficient data integration within an engineering workflow.
