How to optimise production and increase the recovery factor by management practices?
Oil field production activities include the need to solve numerous problems, such as leaks in tubing and packer, poor cementation, leak zone, layer with water with and without crossflow, wrong perforation, water and gas cone, presence of fractures, anisotropy of the reservoir, transition zone, and so on.
The solution goes through the following steps: classification of the flow nature, if the problem is a simple flow or if the problem is multiple, which is the most serious if the problem can be solved independently or in an integrated way, what are the chances of success when control the flow problem, and if a cost-effective solution can be generated.
In any case, integration with reservoir geology always leads to a better solution.

Objectives
Upon completion, participants are expected to understand and seek to optimise the flow of fluids in porous media, through the continuous adjustment of the geological and fluid flow models, with practical approaches related to engineering, geomechanics, problem-solving, and application in production and environmental projects.
