Electrical rock typing using Gaussian mixture model to determine cementation factor [PDF]
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.
