METHODOLOGY TO ACCELERATE EXPLICIT INTEGRATION BETWEEN RESERVOIR AND PRODUCTION SYSTEM SIMULATORS

Resumo

Integrated models are needed in some situations to analyze the interaction between
reservoirs and production system models. However, the dynamics of the two systems is different and
there are situations in which the production system response is very similar over time. The aim of this
work is to propose a more efficient interaction between the simulators, avoiding repetitions, reducing
the total time of the numerical coupling and accelerating the decision making process for the field. The
methodology of this work proposes a proxy model for the production system, similarly to that done in
decoupled approach with VLP (Vertical Lift Performance) tables previously generated, but with the
proxy model being generated during the integrated simulation using explicit coupling. Integration with
proxy model obtained total time values close to those obtained with the use of VLP tables previously
generated, showing an efficient way of efficient interaction between the reservoir and production
system simulators for the explicit coupling approach, without the need to run unnecessary values, as
done in the generation of VLP tables.
