RPSEA's Ultra-Deepwater Technical Advisory Committees (TAC) focus on a particular ultra-deepwater technology area. The role of the TACs, with representation from subject matter experts who study and apply ultra-deepwater technologies in real field situations, is to identify current technology gaps and define the specific R&D efforts needed to address these gaps. As such, the TACs provide a bottom-up, end-user-driven program. There are a total of six UDW TACs. The UDW TACs are open to the public.

The GEO/RES TAC’s goals are to examine trends, develop and optimize techniques, technologies and tools that overcome geoscience and reservoir engineering challenges, while avoiding areas in which participants have competitive concerns.
The focus includes subsalt imaging, reservoir characterization and development, fluid characterization, economics, high pressure/high temperature, geo-mechanics, appraisal, reservoir surveillance and production.
