Development of an inflow performance relationship (IPR) for a slanted/horizontal well

Technical Report ·
OSTI ID:7273085

Since 1968, the Vogel equation has been used extensively and successfully for analyzing the inflow performance relationship (IPR) of flowing oil wells under solution-gas drive. Oil well productivity can be rapidly estimated using the Vogel IPR curve and well outflow performance. However, the Vogel curve was originally developed for conventional vertical wells and may not be valid for slanted and horizontal wells. This report presents the development of IPR's for slanted and horizontal wells by using a vertical/horizontal/slanted well reservoir simulator. The generated IPR's are found to be similar to the parabolic characteristic of the Vogel curve. Several application examples are included to illustrate the use of the newly generated curves. 12 refs., 15 figs., 25 tabs.
