This session will present the advances in drill bits technology used during the development of Brazilian Pre-Salt. Also, an innovative drilling operation with Tethered Blow Out Preventer, allowing the usage of a Dynamic Positioning rig to operate in shallow water will be detailed. Furthermore, well integrity analysis, considering failure modes of structural elements such as casing and cement will be shown. At last, technologies for real time data transmission and digital twin approach will be presented from drilling activities to production phase of the well. Therefore, this section will be a great opportunity to exchange knowledge with several disciplines, regarding performance and safety of wells operations.
