You need to be more specific in your question. All producing zones, thus the wells, are analyzed for their commercial feasibility.
Some for example, will use geosteering or other methods in real time in order to maximize production. Additionally, no wells will be designed "to be the most expensive possible".
Further, drilling programs are based on getting the product to the Christmas tree, and energy companies base their FIDs on a guesstimate of what the unit price for the product is likely to be over the life of a field.
Hope that helps.
