Summary CO2-water-alternating-gas (CO2-WAG) flooding generally leads to higher
recovery than either continuous CO2 flooding or waterflooding. Although CO2 injection …

We consider robust ensemble-based (EnOpt) multiobjective production optimization of on/off
inflow-control devices (ICDs) for a sector model inspired by a real-field case. The use of …

With an increase in the number of applications of ensemble optimization (EnOpt) for
production optimization, the theoretical understanding of the gradient quality has received …

We consider robust ensemble-based multi-objective optimization using a hierarchical
switching algorithm for combined long-term and short term water flooding optimization. We …

Abstract Statoil is implementing “Fast Model Update (FMU),” an integrated and automated
workflow for reservoir modeling and characterization. FMU connects all steps and …

Typical optimization problems in reservoir management (eg injection rates allocation in a
waterflooding project) usually involve a high number of variables to be controlled. Model …

The number of installations of intelligent well (I-well) completions, which are providing layer-
by-layer monitoring and control capability of production or injection, is growing. However …

We consider the problem of finding optimal long-term (life-cycle) recovery strategies for
hydrocarbon reservoirs by use of simulation models. In such problems the presence of …

Field implementation of chemical EOR is subject to significant uncertainty economic and
technical. This study presents a workflow and a method to produce optimal Chemical EOR …
