Investigation of Multiple-Stage Hydraulic Fracturing Efficiency for Lower Miocene, Cuu Long Basin, Continental Shelf of Viet Nam
Abstract
The paper evaluates the multiple-stage hydraulic fracturing efficiency for single wells in the Lower Miocene formation of Cuu Long basin on the continental shelf of Vietnam. The efficiency of multiple-stages is better than that of the base case and single-stage hydraulic fracturing for well stimulation such as the effective radius, average skin factor, fracture conductivity, oil productivity at post-fractured well, fracture length and width, and net pressure. The integrated multiple-stage hydraulic fracturing model includes the minimum horizontal stress and fracture propagation orientation, the fracture geometry model, the production model and the economic model. The study showed that multiple-stage fracturing for single wells produces higher cumulative oil production than unstimulated cases and well single-stage fracturing.
