Earth Science and Engineering and Energy Resources and Petroleum Engineering Graduate Seminar

Abstract

Value creation is achieved only when we can make robust and high-quality decisions. The key input for decision-making is the forecast/prediction capability. Nevertheless, one can’t make good decisions without embracing uncertainties.

Forecast/Prediction competence is nowadays enabled by either models (physics based) or data driven (Machine Learning and Artificial Intelligence) or hybrid (Physics Informed Neural Networks type) methodologies.

The type of decisions ranges from asset level (single reservoir) to area development (multiple reservoirs) and further on to a higher-level portfolio/strategy optimization.

The paradigm-shit that we propose is to move gradually from the data/model/hybrid driven reservoir management towards a decision-driven reservoir management. Starting with a decision space (more than one decision, e.g., alternatives) one should be able to have access to fit-for-purpose models/data/tools tailored to the decisions in hand.

The talk will cover fundamental concepts/technology development/state-of-the-art methodologies/research/algorithms for model calibration (data assimilation), optimization (gradient based and gradient free) and a decision-making workflow which are part of our current research in UiS and their applications/implementations in real life applications.
