... database. The adjustment was made to minimize the deviation in key PVT properties like saturation pressures, densities at reservoir temperature and Stock Tank Oil (STO) densities, while keeping the n-alkane limit of the correlations unchanged. As an improvement of a previously suggested characterization...

... Abstract Drill stem testing of low permeability reservoirs is challenging because high pressure drawdown around the wellbore readily lowers fluids below saturation pressure and creates two-phase flow into the wellbore. The fluids produced at surface no longer represent the original reservoir...

... in solution GOR and saturation pressure with depth from the gradient calculation are shown in Fig. 1 . The reason for taking the composition from the gradient calculation is to cover a wide range of composition, which can be expected in any field. Fig. 2 shows the variation of saturation pressure...

... uncertainty after analysis showed the RFT oil samples to be contaminated with drilling mud. Table 1 shows the range of estimated values for the key fluid property data required in the reservoir simulation model. The saturation pressure, or bubble point, of the oil was estimated to be nearly 5800 psia, only...
