Transmissibility

Created by Arthur Aslanyan (Nafta College), last modified on Jul 11, 2021

Ability of reservoir to translate fluid volumes throughout the pore volume:

(1)	$\begin{array}{l}\displaystyle \sigma = \bigg< \frac{k}{\mu} \bigg> \ h\end{array}$

where

$\begin{array}{l}\bigg< \frac{k}{\mu} \bigg>\end{array}$	multiphase fluid mobility
$\begin{array}{l}h\end{array}$	effective formation thickness

M^-1 L⁴ T¹

m³/(Pa·s)

(md·m)/cp = 9.87 · 10^-13 m³/(Pa·s)

(md·ft)/cp = 0.3048 (md·m)/cp

(md·m)/cp = 8.527 · 10^-5 cmd/kPa = 8.64 · 10^-3 cmd/atm

cmd/atm = 115.741 (md·m)/cp

For a single-phase fluid it simplifies to:

(2)	$\begin{array}{l}\displaystyle \sigma = \frac{kh}{\mu}\end{array}$

where

$\begin{array}{l}k\end{array}$	formation permeability to a single-phase fluid
$\begin{array}{l}\mu\end{array}$	fluid viscosity
$\begin{array}{l}h\end{array}$	effective formation thickness
