Vertical motion (general case)
For the Stokes’ law regime equations 3.88, 3.89 and 3.90 are applicable. For the Newton’s law regime, R_/ρu2 is a constant and equal to 0.22 for a spherical particle. Therefore, substituting in equation 3.81…
Oil and Condensate Removal
In order to process and transport associated dissolved natural gas, it must be separated from the oil in which it is dissolved. This separation of natural gas from oil is…
Production of natural gas
Once a well has been drilled and the presence of commercially viable quantities of fossil fuel has been verified, the next step is actually lifting the natural gas out of…
Motion of a sphere in the stokes’ law region
Under these conditions, from equation 3.5: if allowance is made for the added mass. In this particular case, the equations of motion for the X and Y directions are mutually independent and therefore can be…
Volumetric Method To Estimate Volume In Place and Reserves
Volumetric is a method to estimate fluid in reservoir based on volume of pore space in a rock and water saturation. Volume of Oil Initially In Place (OIIP) To estimate…
Petroleum Reserves Estimation Methods
The process of estimating oil and gas reserves for a producing field continues throughout the life of the field. There is always uncertainty in making such estimates. The level of…
General equations of motion
The motion of a particle through a fluid may be traced because the value of the drag factor R_/ρu2 for a given value of the Reynolds number is fixed. The behaviour…
Compressibility Factor / Z Factor
Compressibility factor of gases is a thermodynamic property which is used to modify the ideal gas equation for real gases. Ideal gas equation states,PV = nRT This ideal gas equation is…
Composition of Natural Gas
Natural gas is a naturally occurring gas mixture, consisting mainly of methane. The gas supplied to Enbridge Gas comes from western Canada, the United States and Ontario producers. While the…
Power-law fluids
Because most shear-thinning fluids, particularly polymer solutions and flocculated suspensions, have high apparent viscosities, even relatively coarse particles may have velocities in the creeping-flow of Stokes’ law regime. CHHABRA(35,36) has proposed that both…
