Selection of a Marginal Field


There are 57 marginal fields. And I want to select ONLY one field to apply for.
How to select such field while I do not have access to the data describing each field?
I mean I can not purchase all data for all 57 fields. Then how to decide that certain field is the best for me?
I understand that I will purchase the data for the applied field after that the decision has been made to go for such field, But how to reach such decision and select one particular field out of 57 fields without reading all data of all 57 fields?
