Multilateral Horizontals -- August 20, 2023

Locator: 45428B.

I'm not sure why, but all of a sudden, out of the blue, out of thin air, a Xweet on multilateral wells popped up on my Xweet account yesterday.

From Schlumberger, April 19, 2021: link here.

From Xweeter yesterday: link here.

For the record, in the Bakken:

• the "standard" well is a two-mile, two-section, single lateral well, spaced for 1280 acres
• there are exceptions
• there are a growing number of three-mile, three-section, single lateral wells, spaced at 1920 acres
• due to geography and administrative boundaries, one will also see 2.5 mile laterals, 2.5 sections, spaced at 1600 acres (2.5 * 640)
• section line wells are still generally "standard" Bakken wells but spaced for four sections, 2560 acres, to capture oil that would otherwise be "orphaned" due to setback rules along section lines.
  
• almost all "Bakken" wells target the middle Bakken and the first bench Three Forks
• some "Bakken" wells target the second bench Three Forks
• there may be some third bench Three Forks wells
• I'm not aware of any fourth bench Three Forks wells
• there are a very few multilateral wells in the Bakken, stacked vertically or same formation but multiple horizontally; rare
• if a well is anything other than the "standard" Bakken well, I tend to point it out, but not always 

Later: I accidentally deleted this comment from Borg, and once deleted, comments can't be re-posted, so here it is:

Way back when - before single or staged fracing, tri-laterals (crowsfeet) were the standard solution for harvesting. See the giant Elm Coullee field in MT. today given how inexpensive it is to drill, it might surprise some that doing parallel laterals in light oil formations might be interesting. need to run #'s and see examples.
