... in modeling. The proposed model predicts the bubble point pressure ( P b ) and the oil formation volume factor at bubble point pressure ( B ob ) as a function of oil and gas specific gravity, solution gas-oil ratio, and reservoir temperature by a boosted decision tree regression (BDTR) predictive modeling...

... density and viscosity. The model utilizes saturation pressure, temperature, oil specific gravity, oil and GHG compositions, GHG critical properties, and equally important, the GHG liquefaction pressure to predict the GHG solubility. The oil-swelling factor is modelled as a function of the oil molecular...

Because the basic idea was for the proppant to flow to the top of the created fracture before the fracture closed, lightweight materials used also in drilling...
