Sentence examples for gas deviation factor from inspiring English sources
Real gas deviation factor.
Finally, it sheds light on the gas deviation factor or compressibility factor that modifies ideal gas behavior.
The gas deviation factor z can be calculated by using Standing-Katz plate that Dranchuk and Abou-Kassem fitted in 1974.
In addition, the chapter gives a review of gas properties including gas deviation factor, gas viscosity, compressibility, and formation volume factor.
These properties are gas specific and can be readily evaluated as a function of pressure and temperature on the basis of existing correlations for the gas deviation factor (z-factor) of natural gases.
The gas density is calculated from real gas law, as follows: pV = ZnRT = frac{ZWRT}{{M_{a} }} (38) rho = frac{{pM_{text{a}} }}{ZRT} = frac{{0.00149406,M_{text{a}} }}{RT} (39 where ρ is gas density in gm/cc, M a is apparent molecular weight, T is the temperature in °R, Z is the gas law deviation factor, and p is the pressure in psia.
Deviation factor of natural gas.
Assumptions: (1) Homogeneous reservoir distributes and sulfur of precipitation is not migration in reservoir; (2) Water drives gas follows piston displacement; (3) Constant gas water viscosity and deviation factor; (4) Ignore capillary force, gravity, reservoir anisotropy and stress sensitivity, slippage, and skin factor effects during the displacement process; .
