Hi afroboy and Strikers, many thanks for your acknowledgments :-) It's an honor to be a part of this brilliant community...

re your question my current understanding is that D2St1 intersected a different horizon at the Middle Wilcox then Duncan #1 and the other wells. I think the 10 mmcfd at D2St1 comes not from the so called "Cypress Eagle" field.

There are two clues for that assumption:

1. D2St1 came on sale in April, but if you check the production database at TRRC you will only find production figures from Duncan #1 for April, if you select the "Cypress Eagle (Wilcox)" field.

2. More evidence for that assumption comes from the Duncan #4 W-1 filing and the drilling unit plat.

The filing explicitly defined two different Middle Wilcox targets:

* one is the well known "Cypress Eagle (Wilcox)" field - it's the primary field for this well and the distance to the nearest well (Duncan #3) is 4,080 feet.

* the second (Middle Wilcox) target is unnamed - it's called "Wildcat", but it is linked to Duncan #2 St1 (!!) as the "nearest well" (distance 2,144 feet).

(... just to make it complete, we have also a third shallower target "Bernhard, W." ...)


To cut it short, it seem that Duncan #4 is:

* a major step out to prove the extend to the west-southwest of the CYPRESS EAGLE Field (distance to the nearest well - Duncan #3 - is 4,080 feet or 1,244m) and

* a southwest appraisal of the producing horizon of Duncan #2St1 (distance to D2St1 is 2,144 feet or 653m)

Remember that the drilling direction of the D2St1 sidetrack is to the southwest and therefore the D2St1 bottom hole is closer to the D4 location and not separated through the fault.

So the Duncan #4 will test the CYPRESS EAGLE field as well as the "WILDCAT" field/horizont where D2 is producing and imagine if both horizons comes in ...
