One way to derive these numbers is to consider the 9 elements listed here: source quality, etc.
We assemble a team composed of two types of people:
1. People who know this area/prospect by having worked the data (e.g., from the Alpha prospect area)
2. People who specialize in specific technical areas and have a lot of experience from many different basins (e.g., a
structural geologist who has worked many fault-related traps)
This team reviews data and interpretation, and assigns a chance of success number (COS) for all 9 on a scale from 0 to 1
A team of experts consider these key elements for each prospect.
They rate the chance of success (COS) for each on a scale of 0 to 1
