Self-supervised similarity models based on well-logging data
Sergey Egorov, Narek Gevorgyan, Alexey Zaytsev
Adopting data-based approaches leads to model improvement in numerous Oil&Gas logging data processing problems. These improvements become even more sound due to new capabilities pr…
Usage of specific attention improves change point detection
Anna Dmitrienko, Evgenia Romanenkova, Alexey Zaytsev
The change point is a moment of an abrupt alteration in the data distribution. Current methods for change point detection are based on recurrent neural methods suitable for sequent…
Deep learning model solves change point detection for multiple change types
Alexander Stepikin, Evgenia Romanenkova, Alexey Zaytsev
A change points detection aims to catch an abrupt disorder in data distribution. Common approaches assume that there are only two fixed distributions for data: one before and anoth…
Similarity learning for wells based on logging data
Evgenia Romanenkova, Alina Rogulina, Anuar Shakirov +6
One of the first steps during the investigation of geological objects is the interwell correlation. It provides information on the structure of the objects under study, as it compr…
