Preemptive detection of high water-cut wells in Delaware basin using a joint unsupervised and supervised learning approach

J Foster, S Misra, Y Falola, M Bhatia - Gas Science and Engineering, 2023 - Elsevier
High water cut has been an issue in the Delaware basin for many years now. Volume of
produced water continue to increase, resulting in adverse environmental impacts and higher
reservoir-management costs. To address these problems, a data-driven workflow has been
developed to pre-emptively identify the high water-cut wells. The workflow uses
unsupervised pseudo-rock typing followed by supervised classification trained on well logs
from 17 wells in the Delaware basin. The workflow requires a suite of 5 well logs from a 500 …
