    Abstract: Method in an oil and/or a gas production system comprising a plurality of oil and/or gas wells each producing a multiphase fluid stream, adapted for predicting change in produced fluids resulting from change in manipulated variables. Fitted model parameters which express the relationship between the change in manipulated variables and the produced fluids are determined from a set of historical production measurements. The method comprises the steps of: a. choosing a model structure which predicts change in produced fluids as a function of the change in manipulated variables, where the predicted change in produced fluids depends on the value of fitted model parameters; b. determining fitted model parameters so that predictions of produced fluids match said historical production measurements as closely as possible; c. determining a quality tag that describes the uncertainty of said predictions of change in produced fluids.

    Abstract translation: 一种在油和/或气生产系统中的方法，所述系统包括多个油井和/或气井，每个油井和/或气井产生多相流体流，适用于预测由操纵变量的变化引起的采出流体的变化。 根据一组历史生产测量结果确定拟合的模型参数，这些参数表示操纵变量和产出流体的变化之间的关系。 该方法包括以下步骤：a。 选择一个模型结构，预测产出流体的变化作为操纵变量变化的函数，其中产出流体的预测变化取决于拟合模型参数的值; 湾 确定拟合的模型参数，使得所生成的流体的预测尽可能接近所述历史生产测量; C。 确定描述所产生的流体变化的所述预测的不确定性的质量标签。
