Several correlations have been reported in the literature to estimate the bubble point pressure of crude oil samples. The bubble point pressure is handled as a function of solution gas oil ratio, gas gravity, oil gravity, and temperature. 1.2.4.1 Standing Correlation Standing (1947) proposed an...
In this work a bubblepoint pressure correlation is proposed which is as accurate as the data permit. Certain correlations, for bubblepoint pressure and other fluid properties, require use of stock-tank gas rate and specific gravity. Since these data are seldom measured in the field, additional ...

A series of experimental studies of frictional pressure drop for single water phase and gas-liquid two-phase bubble flow in two different rolling angles and three different rolling periods were carried out in the paper.Based on the experimental data,a new correlation for calculating single-phase fr...
The visual field photographed through the microscope is a narrow region including the droplet collision point. At the instant of droplet collision, the entrained air is captured by the confinement between the droplet and heating surface. The entrained air is absorbed in many vapour bubbles that are...
as the pressure and temperature drop below their critical points. Depending on the drilling depth, it can take several minutes for the influx gas to rise up to this point where it may become detectable in the drilling process parameters, if the quantity of gas in mud is sufficiently large. ...

The bubble point pressure is a direct measurement of the largest pore in the membrane. Based on the surface tension of the fluid in the membrane pores and the wetting angle of the membrane polymer, the diameter of the pore can be calculated using the Young–Laplace equation, ΔP=(4γ cos...
