Benefits of Tailored Surveillance Efforts in High Viscosity Oil Waterfloods: Case Study from a Major Brown Field in South Oman

摘要

This paper presents the benefits of surveillance efforts adopted for monitoring a waterflood in a geologically complex reservoir that contains high-viscosity (90 cp) oil. The reservoir is part of a large brownfield in South Oman and has been on production for more than 25 years. The development of the reservoir has been carried out in phases and full-field water injection was started after approximately 18 years of primary depletion. The water-flood project is expected to increase recovery factor by about 10% over primary depletion
