Abstract

MéTODO PARA PRODUçãO INDUZIDA DE PETRóLEO EM POçOS POR MEIO DE FRATURAS HORIZONTAIS. é relatado na presente invenção um método para produção de petróleo viscoso em poços por meio de injeção de vapor em fraturas horizontais. O objetivo da presente invenção é alcançado por meio de operações de fraturamento que forma fratura horizontal sendo esta fratura sustentada com agente de sustentação, por exemplo, do tipo bauxita que é resistente ao vapor em regiões do poço (1,11, 12) que atinjam a formação produtora (6) tanto na região da base (61) quanto na região do topo (62). Vapor, associado ou não a outro fluido, por exemplo, solvente orgânico é injetado no poço (1, 11, 12) produtor deslocando o óleo da formação de forma linear e por gravidade.METHOD FOR INDUCED OIL PRODUCTION IN WELLS THROUGH HORIZONTAL FRACTURES. A method for producing viscous oil in wells by steam injection in horizontal fractures is reported in the present invention. The object of the present invention is achieved by fracturing operations that form horizontal fracture, which is a sustained, sustained, for example, bauxite-type fracture that is vapor resistant in well regions (1,11, 12) that reach the producer formation (6) in both the base region (61) and the top region (62). Steam, whether or not associated with another fluid, for example, organic solvent is injected into the producer well (1, 11, 12) displacing the formation oil linearly and by gravity.
