Petrophysical characterization of "Fazenda Alvorada" field for in situ seismic monitoring: a Brazilian case study

In Brazil there are cases of fields with production problems due to very heavy or paraffinic oils. Some of them are currently submitted to Thermal Enhanced Oil Recovery Processes. We are specifically interested on monitoring the steam fronts. The idea is to map its preferential directions of propagation in time, identifying spatial heterogeneities of the reservoir, trying, in that way, to execute a more efficient production program.
