The formation volume factor of a gas is defined as the ratio of the gas volume in the reservoir at reservoir pressure and temperature to the standard produced volume of gas at the surface. In fact, in reservoir and gas engineering, one of the main usages of the real gas equation of state...

Bg is the gas formation volume factor, fraction; Bw is the water formation volume factor, fraction;φ is the coal porosity at a given pressure, fraction; P is the fluid pressure, MPa; t is the production time, h; μg is the gas viscosity, mpa·s; μw is the water viscosity, mpa·...
The error in estimating Z-factor will lead to big error in estimating all the other gas properties such as gas formation volume factor, gas compressibility, and gas in place. In this paper a new accurate Z-factor correlation has been developed using regression for more than 300 data points ...

The storage of CO2 and hydrogen within depleted gas and oil reservoirs holds immense potential for mitigating greenhouse gas emissions and advancing renewable energy initiatives. However, achieving effective storage necessitates a thorough comprehension
factor). The second relies on a fast charge transfer process, viz carrier withdrawal or donation, electron acceptor or acceptor between guest additives and the host material (e.g., carbon nanotubes (CNTs)), reduced graphene oxide (rGO) (categorized as interface-dependent factor) [63]. The ...
The evolution of the star-disk system and the disk chemical composition determines the initial conditions for planet formation. Therefore a comprehensive understanding of the main physical and chemical processes in disks is crucial for our understanding of planet formation. We give an overview of the...
A high amount of fracturing fluid is pumped into the formation, the average volume of recovered water in the shale gas fields of the United States is only 6–10% (Singh, 2016). As a result, the long-term gas production phase is also accompanied by the production of fracturing liquid. ...
The water formation volume factor, at 250 °F and 6837 psia, is calculated using Eq.(2.81), with the volume changes due to pressure and temperature as follows, ΔVwp=−0.0183454 ΔVwT=0.05776263 Bw=1.0383Hence, ρ=66.91/1.0383=64.44 lbm/ft3(1032kg/m3) (d) The viscosi...
