Most early wells were produced on choke settings of 24/64" to 28/64".  Many of these wells now have 18 to 24 month production histories that can be reviewed for decline characteristics.  The industry trend toward more restrictive settings is more recent and there are fewer wells with sufficient production history to provide a reasonable data set.  This link will help to determine which wells belong in each category and when the trend to production on restrictive flow began.

Skip and, or Les, on the play activity map if oil/gas well bottom holes and bores are present with red lines and dots does this mean they have already been drilled?

Parkdota, I did not see any wellbores on the play activity map.  The symbol classifies the current status of the well.  The interactive map has the wellbores for both drilled and permitted wells.

Jack Blake likes the info. available on this website.  Jack is going to email DNR website and ask them to build a decline rate curve for all HS wells showing data form all HS wells from when they were put on line to current date.  Maybe it's already there or some of you Excel gurus can do this from the data already there easily.

BR, see the attached examples.  Conventional represents a well initially produced on a typical choke size (~ 22/64") while Optimized is initially produced on a more restricted choke size (~ 14/64").

The thing is this can't be a historically proven decline curve because the HS wells have not been producing 10 years.  This is a projected decline curve.  Jack would like to see a real decline curve on HS welltest data to date without the future projection.

Thanks for the links, not sure when I will complete my piece, but this is a part of the sum of what I think plays out.

Excellent, well thought out article, Badfish (Papa Roach).  I'm guessing you'll be proven correct.  Only question in my view is the timing.
