Commingle Completion In The Wellbore-02/19/2013

SEC 32 TWP 05N RGE 05W

This is the first comingle completion I have seen. I am not impressed with the rate. To wit:

Sycamore 166 ft perfs

Woodford 130 ft perfs

Hunton 272 ft pers

Total perfs 568 ft

Rate .948 mcfd 187 bod 370 b water/day

This well will generate about $20,000 per day. I have no idea what the decline will be because I believe the Sycamore is a sand and the Hunton is a limestone. I know the shale will decline rapidly.

There is more water to haul than oil which will be expensive. The interesting part is that this test confirms the comingle of the three different geological zones and may set the stage for multiple zone horizontals in the same 640 or 1280 unit.

Can you believe 18 horizontals in one unit?

With 18 horizontals just in a 640 unit you could possibly open up 72,000 to 81,000 feet of perforation as opposed to the 568 feet above. My estimate of the possible total laterals is based on 4000 to 4500 foot laterals in each of the 18 boreholes.

I don't think all 18 laterals would be produced from one well head. Pretty complex hookup for that to happen. But, if all 18 laterals were producing at once through 3 to 6 wells heads the daily production for the 640 would be an interesting number to see and bring joy in the houses of the mineral owners in that unit.

Don,

The possibilities in the 'Future of Oil/Gas Exploration/Production' is mind boggling with fracking.

Yes, it has come a long way since I was on my first frac job in 1958. Always a lot of noise and mess.
