Empirical PVT Correlations for Colombian Crude Oils

Reservoir fluid PVT properties modeling using Adaptive Neuro-Fuzzy Inference Systems

“…In order to examine the viability of proposed models for estimation of OFVF, the same data bank introduced to the ANFIS model was exposed to 13 empirical correlations of OFVF prediction including Standing (1947), Vazquez and Beggs (1980), Al-Marhoun (1988), Petrosky and Farshad (1993), Omar and Todd (1993), Kartoatmodjo and Schmidt (1994), Al-Shammasi (1999), Macary and El-Batanoney (1993), Abdul-Majeed et al (1988), Labedi (1990), Dindoruk and Christman (2004), Frashad et al (1996) and Arabloo et al (2014). The results of this comparison are reported in Table 10.…”

Implementing ANFIS for prediction of reservoir oil solution gas-oil ratio

“…In 1994, Kartoatmodjo and Schmidt (Kartoatmodjo and Schmidt, 1994) proposed nine empirical correlations for several PVT properties using a data bank of crude properties from different geographical regions including a total of 5392 data points. In 1996, Frashad et al (Frashad et al, 1996) presented new empirical correlations for estimating bubble point pressure, gas solubility, oil formation volume factor and isothermal compressibility. To develop the correlations, they implemented the database consisting of 98 PVT laboratory analysis for Colombian crude oils.…”
