Random Update Of The Three Oldest Wells In North Dakota That Are Still Active -- June 1, 2015

I believe these are the three oldest wells drilled in North Dakota that are still active (I could be wrong, and would be thrilled if anyone can provide names of wells that are older and still producing). These wells are celebrating 61 years of production this year.
  • 537, 458/421, Hess, Lalim-Ives Unit A 1, Tioga oil field, Madison/Devonian, t3/54 (Madison) and 9/68 (Devonian); cum 152K (Madison last produced 5/68); cum 1.93 million bbls (Devonian, still producing about 500 bbls/month; as high as 1,340 bbls 11/13)
  • 498, 292, Hess, Tioga-Madison Unit L-132HR, Tioga oil field, Madison, t7/54; cum 1.95 million bbls; still producing about 250 bbls/month; I can't say for sure, but it looks like this well was re-entered and a lateral was drilled in 2006;
  • 443, 409, Hess, Beaver Lodge-Madison Unit S-27HR, Beaver Lodge oil field, t8/54; cum 742K 3/15; still producing about 350 bbls/month; from the file report, 7/03; total drilling days for this re-entry -- 9 days; "Amerada Hess drilled the Beaver Lodge Madison Unit S-27HR2 as a re-entry second leg horizontal well to produce a good Madison trend that is currently not being produced by horizontal technology. The vertical well bore was drilled at an earlier date to a depth of approximately 8,511 feet. The first lateral was drilled along an azimuth of 220 degrees, parallel to the fracture trend, with a vertical section of 1805 feet, approximately 1600 feet being in the Rival B1/B2 Porosity target. The second lateral was drilled along an azimuth of 170 degrees in a southeast direction for a total of 11,098 feet measured depth with a vertical section of 2466 feet in the Rival B1/B2 Porosity target." If I understand the report correctly, the well is producing from the second lateral. If I understand this report, the re-entry was a horizontal, but it was not fracked artificially; it followed the natural fracture trend.
