In the past two plus years in Robertson and Leon Counties ther have been several wells, mostly those drilled and completed by Encana that have IPs of 30 mm+ in what is classified as the Bossier Formation. The cumulative production for some of the wells has been in excess of 10 bln cf since completion in early 2008.
In the John Amoruso Field (Robertson County) and The Hilltop Resort Field (Leon County). The top well in the Amoruso API 42-395-31421, IP 46,494 MCF . The last well in the top 10 IP's for this field was 27 mmcf.
The top cumlative from Sep 2008 to Jan 2010 was also in the Amoruso the S McLean well API 42-395-31186 has produced 11,004,504 MCF.
I know this is not in our immediate area of discussion, but it does show that this prolific geological strata extends much further even if it is in a much smaller area and it being a sand rather than shale.
The Bossier in Robertson County is not a shale. It is known as the Deep Bossier and is not related to the Bossier Shale (Texas nomenclature) and Haynesville/Mid-Bossier (LA nomenclature).
As I stated in the last paragraph, it is sand rather than shale, the point I was making was that IP's over 30mmcf were not as uncommon as readers seem to think. Horizontal drilling and completion completion techniques have raised the bar not only in our area but others. Whether it be Haynesville/Mid -Bossier or Deep-Bossier (Texas) without the evolution of new drilling and completion (20 stage fracs) techniques we would not see these high IP's
Dan, I do not think readers are under the impression that > 30 MMcfd IP's are uncommon but rather that IP's for shale gas wells > 30 MMcfd are uncommon as evidenced that there have only been 3 to date and none outside the Haynesville Shale.
Now if you want to talk high rates, how about the recent discussion on GHS concerning the 705 MMcfd well in PNG. I have 2-3 pictures of the rig during the flow test and you should see the flare.
