What are the best strategies for optimizing production in mature fields?

1 Review your reservoir data

The first step to optimize production in mature fields is to review and update your reservoir data and models. This will help you identify the remaining oil and gas potential, the reservoir heterogeneity, the flow dynamics, and the reservoir management issues. You can use various methods such as seismic surveys, well logging, core analysis, tracer tests, and reservoir simulation to collect and interpret your reservoir data. By doing this, you can gain a better understanding of your reservoir characteristics and performance, and plan your optimization activities accordingly.

2 Implement enhanced oil recovery

The second step to optimize production in mature fields is to implement enhanced oil recovery (EOR) techniques that can increase the recovery factor and extend the field life. EOR methods involve injecting fluids or gases into the reservoir to improve the mobility and displacement of the hydrocarbons. There are three main types of EOR: chemical, thermal, and gas. Depending on your reservoir conditions and economics, you can choose the most suitable EOR method for your field. For example, you can use polymer flooding, steam injection, or carbon dioxide injection to boost your production in mature fields.

3 Optimize your well and surface facilities

The third step to optimize production in mature fields is to optimize your well and surface facilities to reduce downtime, increase efficiency, and lower costs. You can use various techniques such as well stimulation, artificial lift, well intervention, and smart completions to enhance your well productivity and performance. You can also use digital technologies such as sensors, automation, and analytics to monitor and control your well and surface operations, and detect and prevent any issues or failures. By optimizing your well and surface facilities, you can improve your operational reliability and safety, and maximize your asset value.

4 Apply integrated field management

The fourth step to optimize production in mature fields is to apply integrated field management (IFM) that can coordinate and align your reservoir, well, and surface activities. IFM is a holistic approach that involves using multidisciplinary teams, data integration, decision support tools, and performance management systems to optimize your field performance. By applying IFM, you can enhance your collaboration and communication across different functions and disciplines, and make informed and timely decisions based on your field objectives and constraints.

5 Explore new opportunities

The fifth step to optimize production in mature fields is to explore new opportunities that can add value to your existing assets. You can look for ways to increase your reserves, expand your production capacity, or access new markets. For example, you can drill infill wells, sidetrack existing wells, or develop satellite fields to exploit the bypassed or undeveloped hydrocarbons. You can also upgrade your facilities, install new pipelines, or build new terminals to increase your production potential or reach new customers. By exploring new opportunities, you can leverage your existing infrastructure and experience, and create new sources of revenue and growth.

6 Adopt a sustainable approach

The sixth and final step to optimize production in mature fields is to adopt a sustainable approach that can balance your economic, environmental, and social goals. You can implement measures to reduce your greenhouse gas emissions, water consumption, and waste generation, and improve your energy efficiency and carbon footprint. You can also engage with your stakeholders, such as regulators, communities, and investors, and address their concerns and expectations. By adopting a sustainable approach, you can enhance your reputation and license to operate, and contribute to the global energy transition and development goals.
