This paper investigates the rate-pressure behavior of a horizontal oil well with a fully penetrating wellbore producing during the boundary dominated flow regime. Based on linear regression analysis of simulator results, two empirical inflow performance relationships (IPRs) are developed to estimate well performance. A future performance relationship is also developed to allow estimates of future rate-pressure behavior from current test information. The IPR relationships are compared to other horizontal IPRs available in the literature and yield reasonable estimates of well behavior over a wide range of operating conditions.
