These factors are related through an empirical relationship known as the Wyllie time-average equation. When the velocity (transit time, Δt, or travel time, t) of the rock matrix and borehole fluids are known, porosity can be computed the following ways (Eq. 1 to Eq. 4). In terms of velocity, v: ....................(1) where 1. ϕ= … See more Use this section to list papers in OnePetro that a reader who wants to learn more should definitely read See more Use this section to provide links to relevant material on websites other than PetroWiki and OnePetro See more WebJan 10, 2008 · Yet another Vs equation.
