Another work is Xie et al. (2005) who developed a hybrid GA and fuzzy/neural inference system methodology that provides permeability estimates for all types of rocks in order to determine the volumetric estimate of permeability.
In this paper, the permeability of ECC under constant tensile load was experimentally studied using a specially designed displacement-control loading device, providing permeability data for ECC under realistic loading conditions.
Gas permeabilities measured in the laboratory do not equal reservoir permeabilities, whereas well test data are considered to provide reservoir permeability estimates on the condition that the height (thickness) of the test interval is well-known.
Then, these tests will provide gas permeability values for a number of gas pressures.
Perforation processing requires reliable, high speed, robust and adaptable optoelectronic systems to provide controllable permeability and flexibility in thin materials.
The sPS aerogel monoliths are primarily macroporous and conducive to provide air permeability of the order of 10−10 m2.
One face of the sensors was coated with gold/palladium to provide selective permeability to hydrogen and oxygen but not water vapour.
MDT, NMR logs and conventional logs provide formation permeability in different ways though the parameter can be derived in the three kinds of data.
