  • Planning and implementing an EOR project for the pre-salt Lula field

    Jorge Oscar de Sant´Anna Pizarro and Celso Cesar Moreira Branco

    Carbonate reservoirs contain a significant portion of the world’s oil reserves. However, exploitation presents several challenges, primarily associated with their complex pore geometry, large-scale permeability variation and, sometimes, unfavorable wettability. These challenges can become more significant in a deep offshore environment. Since offshore projects need to be planned well in advance, due to the lack of room on platforms for future expansion, initial application of EOR methods needs to be considered from the development’s conceptual stage.
