Random Example of Low IP; Nice Production; Re-Entry Well, Madison -- The Williston Basin, North Dakota, USA

This is an example of how a well with a low IP can still turn out to be a nice well:
  • 12605, 32 (no typo), SM Energy, Elkhorn Ranch 22-35HR, Elkhorn Ranch, Madison pool, t1989; R-2006; cum 242K, 3/12;
From the geologist's report, some paraphrasing; typed in haste; typos may be present; omissions:
"On February 16, 2006, the Nance Petroleum....Elkhorn Ranch 22-35HR was successfully kicked off and later landed for horizontal penetration of the Upper Buckhorn Porosity in the Mississippian Mission Canyon Formation. ... The original horizontal well was drilled in 1989 by Meridian Oil Corporation and abandoned uncompleted after losing the drill string in the Bakken Shale. The Elkhorn Ranch 22-35H as re-entered and subsequently completed in the Upper Buckhorn Porosity zone."

"This single lateral well required 9 days to drill ... Lateral #2 remains un-drilled at this time."
This well is still producing 1,000 bbls / month. Over the lifetime of this well monthly production has been fairly consistent, with a very small decline compared to Bakken wells.
