Join us for a practical, real-world discussion designed for geologists and subsurface professionals who want to understand what happens after the geology is done. This session explores how capital providers evaluate projects once the technical case is established and why some geologically strong opportunities secure funding while others never reach financial close. Learn what investors actually look for, how risk, return, and structure shape decisions, and how to position technically sound projects for commercial success.

This luncheon is held in conjunction with the FENG Energy & Natural Resources Special Interest Group.
