DJ, you are welcome to post anywhere on the site but I wanted to point out that when you post in a sub-group/group page, all the members of that group get a notice email alerting them to your new discussion.  That doesn't happen when you post to the Main Page (Shale Related Topics).  Your discussion will certainly get views but it might miss some of the Austin Chalk Group members who don't log in often.  Viewership for specific location groups tends to drop off if there is disappointing news or few new posts/replies.  It is also an option to post a new discussion to a group page which provides a link to your Main Page discussion.  That way no one who might be interested misses it.  Thanks for posting this.

Ok, I'm not sure how to do that - you have my permission to repost that information to the Main Page. It appears to be significant news to me

LOL.  I know it can be confusing.  You are on the Main Page now.  Here's how you know.

When you click, Add a Discussion on the Main Page (Shale Related Topics) it posts there.  When you are on a sub-group, in the example Austin Chalk, and click on Add a Discussion, it posts there, on the group page.

Thanks for posting this info. One can compare these two wells but the key info here will be how the Pennington well does over time. They have definitely tapped some decent reservoir (assuming that there is some P&P in the AC section but haven't looked at the logs to confirm this). The flowing pressures are good and to be expected at these extreme depths (i.e. below 17,000').

As a plug back recompletion, operator doesn't need a lot to pay out this operation. One of the questions will be does this type of vertical completion merit "new" vertical wells? And at these rates, the answer will be no. Especially in today's price world.

So let's see how this well performs over the next 6 to 12 months.

PS - Was anything posted as to how large the frac was for this zone?

A chalk well without lateral(s) will play out pretty quick once that fracture is draine. Browse the AC wells in the Pitkin/Masters Creek Field and see that even with laterals, many don't play well.

Bob Z, good comment @ vertical AC wells.

If one could access all the vertical AC production that has been established over the years in the Tx / La Gulf Coast trend, I am guessing that much less than 50% of these wells actually "paid out" and money.

The percentage may be around 25% - especially if the analysis could incorporate LOE and SWD costs over time.

I am sure the databases are out there to do this analysis - if someone had the time to dive that deep into this issue.
