WebJun 1, 2016 · Abstract. Pore-space characteristics are of fundamental importance for production forecasting and reservoir management, especially in complex carbonate reservoirs, as they influence both electrical and hydraulic processes taking place in the interconnected, fluid-filled pore space. For theoretical model calculations of permeability … WebThe data show that hydraulic conductivity varies over a wide range. There are few other physical parameters that take on values ranging over 13 orders of magnitude. In practical terms, this wide range of values suggests that an order-of-magnitude knowledge of hydraulic conductivity can be useful. Conversely, it implies that if a third decimal ... WebMay 5, 2024 · The established models for hydraulic conductivity, for example, Mualem , account only for capillary flow and neglect all non-capillary flow processes. However, water in films on solid surfaces and in corners contribute also to hydraulic conductivity, which becomes more and more important in the medium to dry moisture range. dancing cartoons images
