Rezen

Simulation Project Manager

Rezen provides a hierarchical data structure for managing all the simulation runs in a reservoir simulation project. A project contains one or more ensembles, each ensemble representing a scenario the engineer wishes to investigate. Within each ensemble a number of simulation decks can be created, edited and run. The output data vectors can be analysed and plotted on an ensemble or deck basis.

Simulation Run Management

Rezen provides reservoir simulation run management capabilities, supporting a range of industry standard reservoir simulators.Simulation decks can be submitted individually or as a group. Rezen's own job manager can be tailored to each site or Rezen can be interfaced to your existing queueing system.

Proxy Simulator, Proxy Decks and S-Curve Plot

Given a user specified objective function, Rezen can build a proxy simulator equation from the output of the experimental design generated reservoir simulation runs. This proxy simulator is a function of the uncertainty variables. By assigning a probability distribution to each uncertainty variable, proxy decks can be generated and objective function values quickly calculated with the proxy simulator. These values are then sorted and plotted as an S-curve from which p10,p50,p90 values can be extracted.
