... There are many IPR correlations for solution gas drive reservoirs exist today in the petroleum industry. Well performance is described by the term Productivity Index (J). For slightly compressible fluid, Productivity Index can be calculated from Darcy's equation. (1) J = 0.00708 K h...

...). For that the need to use the correct IPR for subjected reservoir is very essential. Since many decades, Vogel IPR equation has been used comprehensively for evaluating the productivity of vertical wells in saturated gas drive reservoirs. Vogel's model successfully evaluates IPR for single porosity solution gas...

... Abstract Presently, analytical models for estimating reservoir parameters for solution gas-drive are restricted to either constant pressure or constant rate assumption. Thus, current models for solution gas-drive do not allow for rigorous analysis of simultaneous variations in pressure and rate...

We suggest that the behavior of multilateral wells under other drive mechanisms is fundamentally similar to that under the solution gas-drive mechanism. We conclude that with respect to the application of multilateral well...
