Abstract

Oil production has been declined in the fractured basement reservoir from these fields of the Cuu Long Basin as those reservoir pressures were highly decreased. To produce oil, those reservoirs from these fields have been stimulated by using various techniques for enhanced oil production. Water injection at secondary recovery to maintain the reservoir pressure has been flooded because this technique has still brought high efficiently oil production, but the high-water cut has been very challenged while producing oil from the reservoirs. The most efficient way to recover oil in the Cuu Long basin is to stimulate the lower Miocene reservoir by hydraulic fracturing. This study presents the effective multi-stage hydraulic fracturing in the lower Miocene reservoir for single X well of the Cuu Long basin on the continental shelf offshore Viet Nam. The calculated results of multistage fracturing show that the average effective wellbore radius, average pseudo-skin, average productivity ratio, fracture conductivity are higher than those of the blanket and un-stimulated case. The integrated model of multistage fracturing consists of fracture geometry, fracture parameters, conductivity and production model.
