Abstract

Current experience in waterflood development of low-permeability production zones suggests that existing process approaches to operation of injection wells cannot prevent formation of self-induced hydraulic fractures.

Self-induced fracture growth interferes with waterflooding process and affects both current oil production and oil recovery factor. In this paper actual field data are used to study the effects of self-induced fractures on predicted oil recovery factors. A new approach to production forecast is proposed in view of presence of production-induced fractures.

Key words:

self-induced hydraulic fracturing, hard-to-recover reserves, water flooding, displacement efficiency
