Ensemble-based methods have been applied with remarkable success for data assimilation
in geosciences. However, they sometimes fail to preserve the geological realism of the …

The current research trend in history matching is to consider more realistic reservoir models
with complex geology. Hence, it is important to be able to update facies models during the …

History matching a channelized reservoir with multiple facies has always posed a great
challenge to researchers. In this paper, we present a workflow combining the ensemble …

Current theoretical formulations of assisted history matching (AHM) problems within the
Bayesian framework, eg, ensemble Kalman filter (EnKF) and randomized maximum …

Preserving plausible geological features when updating facies models is still one of the
main challenges with ensemble-based history matching. This is particularly evident for fields …

The steam-assisted gravity drainage (SAGD) recovery process is strongly impacted by the
spatial distributions of heterogeneous shale barriers. Though detailed compositional flow …

Intelligent wells (I-wells) provide layer-by-layer production and injection control. This flow
control flexibility relies on the real-time operation of multiple, downhole interval control …

Inverse modeling techniques for estimating reservoir parameters (eg, transmissivity,
permeability) utilize some dynamic (secondary) information (eg, hydraulic head or …

The impact of reservoir heterogeneities in the form of shale barriers on steam-assisted-
gravity-drainage (SAGD) production can be analyzed by generating a large number of …

Reservoir characterization is a key step to define the facies connectivity in channelized
reservoirs. Recently, a new paradigm combining production data with geostatistics has been …
