... on the reservoir EUR distribution of changes to any combination of the input uncertainty distributions. This approach incorporated gross rock volume (GRV) uncertainty ranges from channel mapping, petrophysical parameter ranges (by interval) based on an extensive regional analogue database, and a probability...

... by eigenvectors of the data corresponding to the largest eigenvalues. Divided into 10 groups using K-means clustering, we choose the same number of ensembles from each group. Clustering helps to sample unbiased ensembles. It can be a biased sampling without the clustering procedure. We compare uncertainty ranges...

..., the base case. Fractured resource plays, with their abundance of data but extreme variability, provide surprising insights on how uncertainties ranges evolve. This paper will present a practical method to develop confidence curves for important parameters. IDENTIFICATION OF UNCERTAINTIES Ensuring...

.... The study showed that, using currently available data, the major factors affecting the uncertainty are the erosional unconformity surface (PUU), and the facies distribution. Modeling & Simulation uncertainty range porosity geologic modeling Upstream Oil & Gas volumetric estimation...

... estimates with Monte-Carlo derived uncertainty ranges that exclude the actual porosity. Core data provides the best means of quantifying actual uncertainty in the petrophysical deliverables. Methodologies for deriving uncertainties quantitatively by comparison with core data will be presented...

... Abstract In this paper we present two methods for calculating uncertainty ranges for connected hydrocarbon volumes as applied to the Sunrise gas-condensate field, Timor Sea. A "quick look" approach which uses a simplified, exploration scale fault data set. A more detailed fault...
