Title (EN) ITERATIVE METHOD FOR ESTIMATING PRODUCTIVITY INDEX (PI) VALUES IN MAXIMUM RESERVOIR CONTACT (MRC) MULTILATERAL COMPLETIONS
(FR) PROCÉDÉ ITÉRATIF D'ESTIMATION DE VALEURS D'INDICE DE PRODUCTIVITÉ (PI) DANS DES COMPLÉTIONS MULTILATÉRALES À CONTACT DE RÉSERVOIR MAXIMAL (MRC)
Abstract:
(EN) A process for determining the productivity index of a multilateral completion using data from individual laterals and data from commingled well tests is disclosed. The process includes 1) determining the productivity index for each single lateral by iteratively altering the productivity index until the individual lateral flowrate based on a known reservoir pressure is matched and 2) further determining the productivity index by iteratively altering the productivity index until the commingled flowrate is matched. The productivity index may be used to set wellhead pressures and inline control valve (ICV) settings for production.
(FR) Cette invention concerne un procédé de détermination de l'indice de productivité d'une complétion multilatérale au moyen de données provenant de puits latéraux individuels et de données provenant de tests de puits confondus. Le procédé comprend les étapes consistant à : 1) déterminer l'indice de productivité pour chaque puits latéral unique par modification itérative de l'indice de productivité jusqu'à ce que le débit du puits latéral individuel sur la base d'une pression de réservoir connue soit mis en correspondance et 2) déterminer en outre l'indice de productivité par modification itérative de l'indice de productivité jusqu'à ce que le débit confondu soit mis en correspondance. L'indice de productivité peut être utilisé pour régler des pressions de tête de puits et des réglages de vanne de commande en ligne (ICV) pour la production.
