... finite difference methods hydrocarbon reservoirs solution gas drive inflow performance gravity segregation Both Vogel ( 1 ) and Fetkovich ( 2 ) presented a quadratic equation to describe the inflow performance relationship (IPR) behavior of solution gas-drive systems. Both IPR equations...

... method is the fully implicit finite difference method that provides solution stability, even for relatively large time steps. The compressors within the compressor station are modeled using centrifugal compressor map-based polynomial equations. This modeling technique permits the designation of different...
