Analytical Development of an Improved Inflow Performance Relationship (IPR) Model for Solution Gas Drive Reservoirs

Attempts had been made by many authors to develop an inflow performance relationship model suitable for solution gas drive reservoirs. However, they have not as successful most of the developed models suffer from certain degrees inaccuracies and this necessitates need improved economic analysis oilfield greatly depends on ability accurately forecast future productions. Therefore, objective research is Performance Relationship reservoirs employing a purely analytical approach also compare with that existing IPR (Vogel, Wiggins, Fetkovich, Klins Majher). A series expansion pseudo-steady state equation governs fluid flow in radial geometry obtained using Taylor's method infinite truncated after reasonable number terms ensure high degree accuracy while avoiding computational complexity. Moreover, unknown coefficients were determined available reservoir data. Finally, statistical was carried out determine deviation new actual IPR. This shows (with average coefficient determination 0.97) outperforms which it compared. recommended situations where extreme utmost importance. Doi: 10.28991/HEF-2021-02-02-04 Full Text: PDF
