Sentence examples for gas phase permeability from inspiring English sources
k g = gas phase permeability.
TDC with early low ductile deformation is followed by brittle deformation, gas phase permeability in the range of 0.1 5.0 × 10−3 μm2 (which is the same or higher than that of primary structure coals) and TDC with weak deformation (Ju et al. 2012; Fig. 6), gas phase permeability would decrease.
Skins a few mm thick consisting of material whose gas phase permeability is 0.01 of the formation can reduce the specific gas capacity of an SVE well by factors of 2 to 10 or more.
Also for the gas phase The calculated slope from the semi-log plot is given as: frac{{partial mleft( {rho_{w} } right)}}{partial ln t} = m_{text{gas}} = frac{1637mu Q}{khalpha R} = - 1.2195 And estimated gas phase permeability is given as: k_{text{gas}} = frac{{1637mu Q_{o} }}{{halpha Rm_{text{gas}}^ = 17.0,{text{mD}}.
A study of the effect of gas-phase permeability on drying kinetics revealed an interesting phenomenon a reversal of the direction of drying front propagation.
The contrast between the gas-phase permeability of the sand in the fracture and that of the formation is particularly important, with significant effects requiring the ratio to be greater than approximately 50.
The synergy of reverse osmotic effect and anti-water blocking was utilized to develop 180 °C high temperature polymeric micelle drilling fluid system, water loss of drilling fluid at HPHT (high pressure/high temperature) conditions was only 8 ml, membrane efficiency was improved from 0.11 to 0.5, and the recovery of core's gas-phase permeability reached 91%.
Gas-phase permeability (μm2).
Gas-phase permeability at initial irreducible water saturation (μm2).
This paper presents an experimental study of water blocking damage on coal based on the measurements of surface tension, contact angle, gas-phase permeabilities and adsorption and desorption of nitrogen on synthetic coal samples.
However, these features in short slim tube are different: (1) oil-phase relative permeability decreases faster and gas phase relative permeability increases slower with gas saturation, (2) crossing point is lower and endpoint of oil relative permeability at residual oil saturation is 0.473, (3) residual oil saturation is 16.25 % higher.
