A comparative study of heterogeneous ensemble methods for the identification of geological lithofacies

open access: yesJournal of Petroleum Exploration and Production, 2020
Mudstone reservoirs demand accurate information about subsurface lithofacies for field development and production. Normally, quantitative lithofacies modeling is performed using well logs data to identify subsurface lithofacies.

Well-log lithofacies classification based on machine learning for Chang-7 member in Longdong area of Ordos Basin [PDF]

open access: yesYouqicang pingjia yu kaifa, 2023
Lithofacies analysis serves as the foundation for reservoir evaluation. However, due to the limited coring quantity and cost constraints, identifying lithofacies using logging data for uncored wells becomes crucial.
