Flow-Regime-Based Inflow-Performance Relationships of Unconventional Fractured Reservoirs

Al-Rbeawi, Salam
The main objective of this paper is to develop a new approach for constructing the inflow-performance relationships (IPRs) of unconventional reservoirs. The proposed approach focuses on using transient- and pseudosteady-state-flow regimes in developing integrated analytical models for wellhead deliverability and wellbore-pressure decline considering the two wellbore conditions, constantsandface-flow rate and constant wellbore pressure. The motivation is to reduce the uncertainties in predicting current and future performance of unconventional reservoirs.
