Mature Fields and Well Revitalization

Sustainable growth in oil and gas production must stem from a combination of new discoveries and optimized recovery from maturing fields. Therefore, development of mature oil fields has been, and will increasingly be, an attractive subject. Consequently, there is a large number of published studies describing the methodology of mature-field-development practices. However, it is also evident that optimizing the production of mature fields presents great technological challenges for the operators, who must manage production decline over the short term while increasing recovery factors over the long term. There are opportunities for quick wins, but, for long-term growth, a coherent strategy that integrates elements of technology, people, and process must be established.

A significant amount of information is available that covers almost all aspects of managing mature fields. It is critical to have access to the relevant information and to use the right tools to improve decision cycle time. This allows the operators to correct course in a timely manner and to avoid implementing changes in a compartmentalized fashion. It is straightforward to establish processes and follow best practices, but having people with multidisciplinary expertise is the glue that holds all the pieces together. Many in the industry have stressed the importance of properly developing experience and capacity for innovation. However, promoting the culture of innovation requires patience, which is challenging for public companies that are under quarterly pressure.

It is exciting to see that there is no shortage of technological advances, but it is safe to say that there is still plenty of room for key enablers to continue to evolve and to synergize with each other. For instance, chemistry, as a basic science, could play a bigger role in the overall scheme and perhaps, in certain areas, should take the leading role. Nature has designed countless examples of well-choreographed chemical reactions that support the complexity of life. It is conceivable that such intelligent chemistry can also be developed to broaden the role of chemistry in terms of managing mature fields. I hope to see more and more chemistry-related publications in the coming years.

The decline of a field’s production curve is inevitable; good preparation helps to control the process. I remember reading this statement from one of the majors: “Preparations for field maturity must start with first oil.” In parallel, one must also keep in mind that social responsibility, especially the environmental aspect, should be one of the key considerations while establishing the development strategy.

Again, this is where chemistry can bring significant value. For instance, precise fracturing technology that uses less proppant is a good example of new technology that exhibits uncompromised performance that is one step in the right direction. I hope you enjoy reading the selected papers for this month’s feature.
