Kv/kh permeability
TīmeklisTo fix ideas, we will formulate the transformed problem for a single-phase, compressible flow with a constant horizontal permeability kh in the areal (x, y) coordinates, and a variable permeability kv(z) in the layered, vertical z direction. The matrix porosity ϕ(z) may vary with z. Tīmeklis1997. gada 1. okt. · The demonstration of Hashin and Shtrikman [55] is based on a model of the medium built of composite spheres (see Fig. GR3).Each composite sphere is defined by an isotropic sphere with a constant permeability K in and an isotropic concentric shell with a K out permeability. By using the method of self-consistent …

Tīmeklis12 Vertical-to-Horizontal Permeability Ratio • This value may be representative of the matrix kV/kH ratio if there is sufficient core data. • However, core data cannot determine the effective vertical permeability when there are large-scale barriers to vertical flow, as shown in the Figure. Tīmeklis2024. gada 4. apr. · The Kv/Kh range assessment was done after integration with whole core data and pressure transient data. The impact of Kv/Kh on water and miscible WAG injection processes has also been investigated. ...
