Follow up to prior post “AI teaches itself - no manual labels required” 03.08.2021. Perspective - day in and day out, geologists, engineers, and analysts are active players in asset evaluation and project economics. 80 of the time spent on generating oil and gas projects: exploring ideas with a map, finalizing investment decisions and picking well locations on a map. And what else we may do the other 20 Due diligence and risk assessment. A common issue is the time and effort it takes to p...
