Without a doubt, mature fields are technically and economically challenging.
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.
