Abstract

Summary

The CCS scenario in Brazil is very promising, as the country possesses vast sedimentary basins containing saline aquifers with great potential for CCS projects. That is the case of the offshore Jubarte saline aquifer, composed of turbidite channels of excellent perm-porosity. Focusing on this reservoir, the National Oil Company, Petrobras, is developing a CCS project to meet the demand from industrial sectors in the area, which face specific challenges for decarbonization. The project base case intends to drill seven vertical wells, injecting 1 to 7 million tons/year of CO2 over twenty-five years; the total mass expected to be injected will reach 137 million tons, with an estimated storage capacity of 260 million tons of CO2. Additionally, the drilling of two monitoring wells is planned, with the monitoring period extending up to forty years after the end of injection. For the design of this project, it was necessary to conduct detailed studies and analyses regarding the geological, geophysical, dynamic, and geomechanical aspects of the reservoirs. More specifically, this work will focus on the geomechanical aspects, incorporating results from the other disciplines into a workflow that provides a full-field 3D geomechanical model using finite elements and a probabilistic fault reactivation analysis.
