... 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...

... temperature gradually decreases with the decrease of well depth and HFR often appears in the upper half of wellbore. (d) the increase of gas production and formation temperature is helpful to shorten the length of HFR in the string, which is due to the increase of gas production and reservoir temperature...

... at standard atmospheric conditions except the imbibition studies, which were conducted at reservoir temperature. Our soy-based surfactant reduced the IFT by 60% and changed wettability from oil-wet to water-wet at concentrations lower than 3 gpt. No estrogenic or anti-estrogenic activity was detected...
