... deep neural network to estimate oil formation volume factor at bubble point pressure as a function of gas-oil ratio, gas gravity, specific oil gravity, and reservoir temperature. Deep learning is applied in this paper to address the inaccuracy of empirically derived correlations used for predicting oil...

... We utilize the mathematical model presented in ([ 1 ], [ 2 ]) which leads to late transient solution (LTS) as follows: Once the bubble point with various GOR-values are obtained from conventional CCE measurements, we create a synthetic live oil with a target bubble point and perform pressure...

...) and triple-scale (bulk, 15 nm, and 5 nm) systems are simulated. The first bubble emerges from the bulk region at a lightly suppressed "apparent" bubble point pressure. Below the bubble point, the liquid saturation in the bulk region drops sharply, but the fluids in the nanopores are undersaturated throughout...

... of the correct in-situ oil bubble point in shales which is critical in the optimization of hydrocarbon production. Shales are nano porous organic-rich sedimentary rocks that act as both source and reservoir oil and gas systems. The effect of nano pore confinement on the bubble point of oil in shales has been...

... reservoirs. CPGs (pore diameters 4.3 and 38.1 nm) infiltrated with hydrocarbons (octane, decane, and the binary mixture) are subject to differential scanning calorimetric (DSC) analysis. It's observed that the bubble point is affected by pore size dramatically: at 38.1 nm the confinement effect...

... that the suppression of the bubble-point pressure impacts saturated portion of the liquid formation volume factor and extends the undersaturated portion of the curve. The gas composition is different for each supersaturation level and the gas is composed of lighter components as the supersaturation (bubble point...

... formation coupled with the slow release of solution-gas below the bubble point pressure poses severe challenges to production operations such as fluid sampling, hydrocarbon recovery, and flow assurance. Note that heavy oils might on occasion exist in the reservoir as a Pickering emulsion (e.g. stabilized...

... falls below the bubble point, flow instabilities will increase dramatically. The onset of instability can be predicted using a transient multiphase simulator such as OLGA 1 , and techniques to minimize instabilities can be quantitatively investigated through simulation. This paper describes flow...

... is normally in two distinct parts: while the fluid is a one-phase liquid, the pressure falls rapidly with decreasing volume, corresponding to the compressibility of the oil; once below the bubble point pressure decline is much slower since the increasing proportion of gas greatly increases the compressibility...
