Jubarte PRM System Manufacturing and Installation Lessons Learned

Upon successful installation and acquisition of 4D data from the Jubarte pilot PRM system, we would like to share some of the lessons learned from the Jubarte experience. Discussion includes the technical challenges and supply chain difficulties that needed to be overcome. We successfully dealt with manufacturing and installation challenges, leading to the delivery of the system in 2012. After the third active acquisition of seismic on the field, the system continues to operate providing excellent data to Petrobras. As a result of the data from the Jubarte PRM system, decisions have been made by Petrobras to relocate various well placements. During the process we have taken the issues and incorporated them into a new revision of the system which shall also be explained, comparing the current “Next Generation” OptoSeis design to that which was installed on the Jubarte field. While the design changes are subtle they will lead to a more cost effective and reliable system in the future.
