The simulations are performed using a black oil model. The PVT for the two reservoirs are different and were handled slightly differently as described in the next sections.
Fluid Properties
SFR Reservoir
The saturated data is available in tabulated form and covers the range 1000−4300 psi for saturated oil and 1000−8000 psi for gas. In order to expedite the computations we interpolate the data to supply an analytical model for the black oil PVT.
SCA Reservoir
The saturated data is available in tabulated form and covers the range 500−7000psi. Again, in order to expedite the computations we interpolate the data to supply an analytical model for the black oil PVT. The main difficulty with the provided tabulated data was that the reservoir had to be operated, during the final phases of the simulations, at bubble point pressure in the range 50−110 MPa which was well above the last tabulated data point, which required special arrangement.
