ADJOINT-BASED CONDITIONING OF PROCESS-BASED GEOLOGIC MODELS

摘要

A method for correlating data predicted by a process- orphysics-based geologic model to describe a subsurface region withobtained data describing the subsurface region. Data is obtained describingan initial state of the subsurface region. Data describing asubsequent state of the subsurface region is predicted. The predicteddata is compared with the obtained data taking into account whetherthe obtained data or the predicted data represent a discontinuousevent. A sensitivity of the predicted data is determined if the predicteddata is not within an acceptable range of the obtained data. The datadescribing the initial state of the subsurface region is adjusted basedon the sensitivity before performing a subsequent iteration of predictingdata describing the subsequent state of the subsurface region. Arepresentation of the subsurface region based on the data describingthe subsequent state of the subsurface region is outputted.
