The inherent uncertainties in numerical reservoir simulation can lead to models with significant differences to observed dynamic data. History matching reduces these differences but often neglects the geological consistency of the models, compromising production forecasting reliability. To address this issue, this work proposes a geological modelli...

The Norne Field reservoir sandstone comprises Early–Middle Jurassic interbedded sandstones and shales to massive sandstones with some thin continuous cemented interlayers. A detailed characterization of the geological heterogeneities through electrofacies analysis, together with the simulation grid refinement, has been used to derive representative...

Some difficulties are frequently associated with the integration of seismic and flow simulation datasets, especially related with the low vertical resolution of the seismic data and the uncertain estimations in the areas between the wells. One challenge is then the integration of both datasets in different scales, in order to take advantage of thei...

Integrating different datasets such as flow simulation and seismic data is still a big challenge to the industry mainly because these datasets have different resolutions. A current practice, in quantitative approaches, is based in upscaling/downscaling methods to equalize the different scales. Upscaling methods normally yields a smooth effect and t...

Here we present the main results of a study of the high-resolution stratigraphy of the Lower Jurassic organic-rich marine series in the Lusitanian Basin, Portugal. In this basin, the Lower Jurassic consists mainly of an alternating marl–limestone succession (upper Sinemurian–Toarcian), with some intervals enriched in organic matter (upper Sinemuria...

This work presents the main results of the Project ”High resolution stratigraphy of the Lower Jurassic organic-rich marine series in the Lusitanian Basin (Portugal)”, supported by the Portuguese Foundation for Science and Technology. This project was focused on a multidisciplinary stratigraphic analysis based on the study of a range of biotic and a...

Abstract: This work provides detailed information of outcrop gamma-ray logging from the Lower Toarcian marly-limestone series of the Lusitanian Basin (Portugal). The study included total and spectral gamma-ray measurements in outcrop and laboratory and whole-rock mineralogical characterization by X-ray diffraction, carried out in three different se...

This work provides detailed information of outcrop gamma-ray logging from the Sinemurian-Pliensbachian organic-rich units (Agua de Madeiros and Vale das Fontes formations) of the Lusitanian Basin, which are recognized as one of the most important potential oil source rocks interval of Portugal. The study included total and spectral gamma-ray measur...
