This is a spreadsheet for April 2008 showing the oil and water production for the Bakken wells in Mountrail County. It is sorted by the top water producer as a percent of oil production. I am not sure any firm conclusions can be drawn from this data other than Hess’s name appears a lot as does Brigham’s name. The frequency by which their wells encounter water could be more a function of where they are drilling than their drilling and completing skills.

The part I haven't figured out is that frequently you see initial production figures in which bopd and bwpd are listed, and the water number frequently is as large or larger than the oil number.But once a well goes into production,if your data are correct, the amount of water apparently drops drastically, to just a small percentage of the oil produced. (In the case of Geving 09, iirc, the initial production was 895 bopd and about 1600 bwpd) I never did quite figure out how the operators were disposing of all the water if they were dealing with as much or more water than oil coming from a well. But this all seems a lot simpler if the amount of water is just a small percentage of the oil for a typical well in production.
Do the water numbers include only formation water, or do they include load water as well? Or is there any way to know?
Where did Larry get that data. I am looking for data on well 16664
This data comes from the NDIC Subscription website.
Well 16664 produced 5421 barrels of oil and 15 barrels of water in May.
Is the water part of the millions of gallons
they use to fracture??
Quite often the initial production test is done with a fully opened valve on the wellhead.
This helps define the widely touted initial BOEPD rates you see.
However, once the cooler heads start to prevail and a little better understanding of the pressure losses associated with an unregulated flow the valve will be closed or "choked". Often this is measured as a fraction in XX/64.
Very often you can reduce the amount of produced water by choking the well back. Oil being lighter than water does matter. And so does the cost of disposal of the salt water produced.

what are the production numbers for wells 17145, 17075, and 17154?
