Without a doubt, mature fields are technically and economically challenging.
Water handling, stimulation, artificial lift, surveillance and new development plans require creative solutions based on alternative approaches. Therefore, several independent companies, as well as national oil companies operating these fields, demand renewed investments in technologies, training, and research to increase the recovery factor and optimize production.
The Brazilian mature onshore basins are still prolific after decades of production and have a myriad of profitable opportunities to all operators. The challenge is determining what can be done to increase their Recovery Factor, aiming to improve the reserves. Some of the actions include but are not limited to stimulation, re-completion, chemical\water\steam injection, modification of tax structures, extensive infill drilling, accurate reservoir monitoring and management, and the optimization and operation of proper production technologies. Additionally, there is always space to discuss cost efficiency and opportunities for cost reduction.
