Abstract: A method for deriving VOI for a hydrocarbon-bearing reservoir fluid model based on DFA data (“true fluid model”) versus an “incorrect fluid model” includes calculating first, second and third objective functions that are based on NPV(s) of simulated production by a reservoir simulator with different configurations. For the first objective function, the simulator is configured with the incorrect fluid model and control variables that are optimized to derive a first group of control variable values. For the second objective function, the simulator is configured with the true fluid model and the first group of control variable values. For the third objective function, the simulator is configured with the true fluid model and control variables that are optimized to identify a second group of control variable values. The objective functions can be deterministic, or can include statistics that account for uncertainty. A visualization of such results with uncertainty is also described.

Abstract translation: 基于DFA数据（“真实流体模型”）与“不正确的流体模型”相比，用于导出含烃储层流体模型的VOI的方法包括计算基于模拟的NPV的第一，第二和第三目标函数 通过不同配置的油藏模拟器生产。 对于第一个目标函数，模拟器配置有不正确的流体模型和被优化以得到第一组控制变量值的控制变量。 对于第二个目标函数，模拟器配置有真实流体模型和第一组控制变量值。 对于第三目标函数，模拟器配置有真实的流体模型和被优化以识别第二组控制变量值的控制变量。 目标函数可以是确定性的，也可以包括考虑不确定性的统计学。 还描述了具有不确定性的这种结果的可视化。
