Title (EN) APPARATUS AND METHODS FOR DOWNHOLE FLUID SEPARATION AND CONTROL OF WATER PRODUCTION
(FR) PROCEDE ET DISPOSITIF DE SEPARATION DE FLUIDES DE FOND DE PUITS ET DE REGULATION DE LA PRODUCTION D'EAU
Abstract:
(EN) The present invention relates to a system which prevents coning while minimising the problems associated with any reverse coning which may result. The system includes a production string disposed within a wellbore having both oil production perforations and water production perforations. The produced water is separated into oil and water, whereafter the water is reinjected into a disposal zone. The separated oil is directed upward through the production string for recovery. Coning may be further prevented by monitoring the oil/water contact and by adjusting the rates at which the two zones are produced.
(FR) La présente invention concerne un système de lutte contre les phénomènes de succion permettant de minimiser les problèmes liés aux phénomènes de succion inverse pouvant en découler. Le système comporte un tube de production disposé à l'intérieur d'un forage et comportant des perforations de production de pétrole et des perforations de production d'eau. L'eau produite est séparée en pétrole et eau, à la suite de quoi on réinjecte l'eau dans une zone de rejet. Le pétrole de séparation est remonté par le tube de production pour y être récupéré. On peut également lutter contre les phénomènes de succion en surveillant le contact pétrole/eau et en adaptant les débits de production des deux zones.
