Abstract
In this paper, we demonstrate how we can combine reservoir physics, data and knowledge with fit-for-purpose machine learning algorithms in a graphical network model to utilise reservoir models as part of an efficient discovery process. Contrary to a traditional reservoir modelling approach, where we integrate data in a sequential manner, we train the graphical network model by utilising the information in all available simultaneously. This help overcome the common pitfalls in reservoir modelling, which typically limits the value of reservoir modelling efforts in asset teams today. We demonstrate the value of the solution on a study conducted on the Norwegian continental shelf. By having the ability to quickly generate reservoir models that all are plausible given the current available data, under different prior assumptions regarding the subsurface, we both increase our subsurface understanding, by also the confidence in our reservoir management decisions.
