2-Million-Barrel EURs in the Bakken? -- Michael Filloon

As Don says, "lots of numbers and EURs of 2 million barrels." That about sums it up, the "it" being Mike Filloon's most recent column.

Mike provides a great discussion of the various factors affecting production, decline rates, and EURs in the Williston Basin Bakken. But with modeling he shows several EOG short lateral wells in the Parshall oil field with EURs of one million bbls. Had they been long laterals, they would have modeled to two million bbls.

At the link, check out Table 5 and note the number of short lateral, Parshall oil field, EOG wells that model greater than 750,000 bbls. Here are just four of them:

• 16713, 781, EOG, Austin 1-02H, Parshall, t12/07; cum 486K 11/12; now, 2K/month
• 16371, 918, EOG, Ehlert 1-35H, Parshall, t4/07; cum 465K 11/12; now, 2K/month;
• 16768, 1,441, EOG, Austin 2-03H, Parshall, t12/07; cum 535K 11/12; now 2K/month;
• 16795, 1,519, EOG, Austin 4-09H, Parshall, t12/07; cum 545K 11/12; now 2K/month;

Comments:

• these were short laterals; most laterals in the Bakken are now long laterals
• completion techniques have probably improved since 2007 when these wells were completed
• northeastern McKenzie County might have even better wells than these Parshall wells

Having said that, in a recent column, Mike's modeling revealed EURs of 1.5 million bbls in Croff oil field and the "Helis Grail."  Be that as it may, these are staggering numbers.
