An important challenge in basin modeling in structurally complex areas is to take into account the flow properties of faults and their evolution through geological time. Numerous parameters must be taken into account as the relative chronology between strain, burial, fluid overpressures and associated diagenesis. Tumbes and Talara basins represent good examples of basin where the gravitary syn-sedimentary fault dynamic and flow properties need to considered for a better assessment of the petroleum system. They are part of a siliciclastic atypical forearc system located south of Ecuador and north of Peru and host, among others, the giant oil field of Talara. These underexplored basins are well documented with 2D and 3D seismic data, wells and fieldwork, that allowed to build two restored sections on which basin modeling will be based. 

The main questions for this study are:

  • What link shale diagenesis, fluid overpressures, shale diaper emplacement and fault dynamic?
  • What are the syn-sedimentary fault flow properties from their initial burial to exhumation?
  • How to explain the atypical thermal regime of these forearc basins and what is the impact on the petroleum system assessment?

The student will make a first assessment of the petroleum system and fluid flow pathways, taking into account realistic flow properties for syn-sedimentary faults. Then a multiscale characterization of critical fault zones will be required, from the field to thin-sections, in order to constrain the relative chronology between burial-diagenesis and strain, and to have a better understanding of the impact of faults on overpressure generation, shale diapirism, and reservoir property evolution.
