Deep convolutions for in-depth automated rock typing [PDF]
Computers & Geosciences, 2020 The description of rocks is one of the most time-consuming tasks in the everyday work of a geologist, especially when very accurate description is required. We here present a method that reduces the time needed for accurate description of rocks, enabling the geologist to work more efficiently.

Electrical rock typing using Gaussian mixture model to determine cementation factor
Journal of Petroleum Exploration and Production Technology, 2023 Many studies have worked on the estimation of fluid saturation as an important petrophysical property in hydrocarbon reservoirs. Based on Archie's law, proper determination of cementation factor (m) can lead to accurate values of water saturation.
