Geology for Shallow Wells (Heterogeneous Formation)...

A shallow field will form a rectangle no smaller than 4 ´  4 and no bigger than 8 ´ 8 squares. The intermediate channel will go through each shallow field, and oil at the shallow depth will not be found in the channel’s path.

The OilFinancier map has 2 or 3 shallow fields.

The shallow fields are not homogeneous: there will be squares in the shallow field that have no oil. On the exterior of the shallow field, the probability is approximately 90% of finding oil. In the interior, the probability is approximately 60%. Please note that these probabilities apply to each shallow field, not to the total of all shallow fields.

 

Economics of Shallow Fields  

Shallow wells have a quick payout, so they are great to recover your investment rather fast. But they decline rather quickly and have little value after 50 OF Days. 

When a shallow field is first discovered, there's not much logic to which adjacent oil rights have oil and which do not. After several shallow locations have been drilled, one can start seeing possible boundaries―and make decisions accordingly.

The shallow field is also the "seismic" for the intermediate field. So after a few shallow wells are drilled, one can conjecture possible paths for the intermediate field―and make decisions accordingly.   

 

Also note that the intermediate channel meandering through a shallow field does not count as part of the locations where there is no oil within a shallow field.

One shallow field—and only one shallow field—will touch a deep field.
