Evaluation of inflow performance of multiple horizontal wells in closed systems

This work presents a model to investigate the inflow performance relationsh ips (IPR) of horizontal and vertical wells in a multi-well pattern. The mod el carl be used to compute the overall and individual well performances. It is shown that stabilized IPRs may not be sufficient for the evaluation of horizontal well performances due to prolonged transient pow periods. The re sults presented ire this peeper clearly indicate that inflow performance of wells in a multi-well pattern is a dynamic concept; a,ld especially bl the prediction of future performances, dynamic rather than static IPR models s hould be used.
