How Does Bakken Compare With Oklahoma?

Petro-Hunt is using the same technology in both the Bakken in North Dakota and in their shale holdings in Oklahoma: horizontal drilling and fracturing of shale for oil.

For newbies, Bakken wells produce about 500 - 1,000 barrels/day for the first few days, and then drop off significantly to plateau at about 200 to 300 bopd.  It is common to see 30,000 to 75,000 barrels of oil in the first three months which equals 800 barrels per day for the first 90 days. (Many wells do much, much better, but there don't seem to be many wells below the 30,000 mark, or 300 bopd for the first 90 days. I assume I will get many comments for these numbers, and/or chuckling by those much smarter than I.)

Anyway, with that background, Petro-Hunt announced today that it has completed another well in the North Oklahoma Oil Project today.
There are two pay zones, an upper zone and a lower zone. Based on the "oil shows" and "swab testing", the lower zone "will produce in excess of the No. 1 well which tested at 80 bopd under similar conditions. Engineers believe flow rates from the oil shale zone combined with the upper pay zone could ultimately result in over 200 bopd of production." 
Because I don't understand oil jargon completely and I certainly don't understand the Oklahoma shale oil, some of the above may be a bit off. But if there is any apple-to-apple comparison allowed between the Oklahoma shale and the Bakken shale, I find the Oklahoma production interesting.
