Abstract Virtual Flow Metering (VFM) is an increasingly attractive method for estimation of
multiphase flowrates in oil and gas production systems. Instead of using expensive …

There has been great progress in data assimilation within atmospheric and oceanographic
sciences during the last couple of decades. In data assimilation, one aims at merging the …

The use of ensemble Kalman filter techniques for continuous updating of a reservoir model
is demonstrated. The ensemble Kalman filter technique is introduced, and thereafter applied …

A method based on the ensemble Kalman filter (EnKF) for continuous model updating with
respect to the combination of production data and 4D seismic data is presented. When the …

In the management of reservoirs it is an important issue to utilize the available data in order
to make accurate forecasts. In this paper a novel approach for frequent updating of the near …

This paper applies the ensemble Kalman filter (EnKF) to history match a North Sea field
model. This is, as far as we know, one of the first published studies in which the EnKF is …

A recursive ensemble Kalman filter (EnKF) is used as the data assimilation scheme to
estimate strength and stiffness parameters simultaneously for a fully coupled hydro …

Most model-based control and estimation techniques put limitations on the structure and
complexity of the models to which they are applied. This has motivated the development of …

Fractured reservoirs are highly heterogeneous and can be characterized by the probability
distributions of fracture properties in a discrete fracture network model. The relationship …

Advancements in horizontal-well drilling and multistage hydraulic fracturing have enabled
economically viable gas production from tight formations. Reservoir-simulation models play …
