WebTraditionally, permeability upscaling is carried out either using analytical upscaling methods like arithmetic/harmonic averaging or numerical upscaling methods like local/global flow-based averaging. Analytical upscaling methods are only accurate for layered or homogeneous medium. WebPermeability: Harmonic-Average Permeability. Permeability variations can occur laterally in a reservoir as well as in the vicinity of a well bore. Consider Figure 2‑24 which shows an …

As p = 0 is invalid for averaging it is superseded by p → ∞ which gives the geometric mean. It is well known that the use of these means leads to upscaled properties related by (4) harmonic mean ≤ geometric mean ≤ arithmetic mean

WebNov 11, 2007 · Abstract. The primary sources of rock permeability data are cores and logs. Core-based permeability data are sampled from the reservoir at different scale from log-based permeability data. Consequently, porosity-permeability cross-plots from core plugs and logs are sensitive to the methods used in averaging the permeability data.
