It is listed as “BOPD” (Barrels Oil Per Day) and “BWPD” (Barrels Water Per Day).
An example below, and notice the second well listed does not give any production numbers: The “per day” in this case is the first 24 hours of measured production and not necessarily the first 24 hours of preduction.
Of the 1,127 wells in this sample, 87 or 7.7% had no third month production.
We can now say, with very strong conviction, that the first 24 hours of measured production will tell us just how well that particular well is likely to perform in the future.
I think this leaves little doubt that the BOPD number that the NDIC reports in their Daily Activity Report Index is a very good guide to what kind of future production we can expect from any particular well.
But it was mostly because only a little over half my data overlapped his.
From his data I used the 2nd and 3rd months production data because the first month’s data was often for less than one full month.
Using the well numbers, I have managed to match 1,127 wells in my database with the same well number in Enno’s data.
There were a more matches than this but had no data or incomplete data.
This is a drop of 84 BP/D or 20 percent from the second to third months. However I collected some data of my own from July and August 2014.
If you go to NDIC Oil and Gas Production Report, you find data on all wells previously brought on line.
In the NDIC’s Daily Activity Reports they publish “WELLS RELEASED FROM “TIGHT HOLE” STATUS” as well as “PRODUCING WELL COMPLETED”.
By searching these two lists, then eliminating the duplicates that appear on both lists, we find that perhaps 70 to 80 percent of all wells report their first 24 hours of measured production.
Sorting all wells by the second months production we see a very strong correlation to the first 24 hours of measured production.
