Interpretable Machine Learning for Estimated Ultimate Recovery (EUR) Prediction for the Bakken Tight Oil Play, Williston Basin, USA

Journal of Petroleum Geology, EarlyView.
ABSTRACT Estimated Ultimate Recovery (EUR), often calculated from production decline curve analysis (DCA), is a key indicator of long‐term well performance in petroleum reservoirs, including unconventional plays such as the Bakken Formation in the Williston Basin in the northern United States, which is the objective of this study.
