... factor, solubility ratio and saturation pressure were determined based on PVT (pressure/temperature/volume) experimental measurements for methane and olefin mixtures. Those properties are crucial for the mixture volumetric behavior knowledge at downhole conditions especially when gas enters...

...) there is evidence that fluid properties have a direct effect in the strong water breakthrough at the time that the saturation pressure is reached in the reservoir. These reservoirs undergo substantial changes in volume and composition, due to its high oil formation volume factors that cause a sudden advance oil...

... of laboratory experiments. This EOS will be used for EOR simulations under gas and nitrogen injection processes. The Peng-Robinson EOS was used to match the PVT experiments. Included in the matching parameters was the variation of the saturation pressure of the gas condensate due to nitrogen injection...

... The VEE3 reservoir was originally undersaturated with 3.850 psi @ 6.900 ft ss. Saturation pressure was estimated from PVT data at 3.322 psi. Current fluid distribution within the reservoir shows a segregated gas cap with an oil ring. First commercial production was in May 1.960. This reservoir...

... consistent with the measured pressure gradient and an acceptable contamination level in the case of OBM. Small analytical laboratory packages designed for offshore use are available. The saturation pressure for a gas-condensate is more difficult to measure on site and will not be readily available. For a gas...

... Abstract Volatile Oil reservoir are sometimes evaluated as gas and condensate systems when pressure in the well neighborhood reaches values fairly below saturation pressure. This pressure drop is common in almost all reservoirs at late depletion stages or from the beginning in tight formations...

... of procedure: First, keeping the theoretical values of Omega and Omega we calculate the interaction coefficient sigma CH4 - C+ that matches the saturation pressure of the mixture. In a second step, the parameters Omega and Omega for the CH4 and C+ fractions are fitted through a non-linear least squares...

... saturation pressures are updated at the end of each timestep. Due to the problem complexity, the validation of the model has been provided to the steady-state flow case, which presents a known analytical solution for compositions and saturations. Examples of application of the computer model to depletion...

A new equation was developed for estimating gas gravity, which eliminates the need to know the gas gravity...
