This talk looks at practical strategies, processes and applications for mature fields, focusing on reducing operational costs and maximizing value creation from existing wells and facilities. You will take away tools and processes that you can apply quickly, efficiently and low cost, to maintain and maximize production and injection. In mature field operations, the primary focus is on safety and keeping costs down. We will show that Production Optimization can rejuvenate a mature field and can extend its profitable life. This is done by building integrated teams, using data analytics, carrying out Produce the Limit workshops and identifying opportunities to debottleneck, rejuvenate and optimize wells and facilities. It is important to look just as closely at water injection, as well as oil and gas production, to optimize reservoir management and maximise recovery. We will demonstrate that by identifying and capturing these opportunities, ranking and prioritizing them, the team can then focus on efficient and effective delivery. This maintains, restores or increased production and injection, which extends profitable field life, maximizes recovery and reduces unit costs. A number of case studies will demonstrate that with whatever data you have, you can always find opportunities to increase production. This is done by safely manipulating the operating envelopes of existing wells and facilities, carrying out systematic well and reservoir surveillance, optimizing chemical treatments, daily artificial lift optimisation, maximizing facility capacities, implementing low cost interventions, locating remaining oil and gas, restoring shut-in wells, as well as workovers and sidetracks, when the prize is significant.
