Random Look At Seven (7) Whiting Wells In One Drilling Unit In Sanish Oil Field; No Obvious Halo Effect; No Obvious Interference -- December 28, 2014

In a long note like this, you should assume there are typographical and factual errors. If this information is important to you, go to the source. Opinions expressed are those of the author and should not be construed to be anything more than personal opinions, which with $1.89 will get you a cup of Starbucks coffee. 

These seven wells were spud in section 3-154-92; they are long laterals extending in a west-southwesterly direction. All of them are entirely in sections 3/2 except for #21934 which is almost entirely in section 10/11; and #19517 whose tip (toe) extends slightly into section 11 (spud from north to south):

Comments about production profile:
  • 18233: nothing unusual; taken off-line for 13 - 18 days in the months of: 11/10; 5/11; 8/11; 10/11; 
  • 18928: taken off-line for half the month, 12/10 after huge production months before; taken off-line for almost all of 2/11 and 3/11; off-line for half the following month, 4/11; off-line for 11 days, 6/11; 
  •  off-line for half the month, 4/12; off-line almost the entire month, 4/13;
  • 19029: taken off-line almost the entire month, 1/11 after huge production months before; off-line for about half of each of months 4/11, 5/11, 6/11; off-line for 11 days 6/12; 
  • 19517: really huge production first three months; off-line most of the month 5/12; 
  • 21773: up to this point, the poorest performing well in this section; 30 stages; 2 million lbs (similar to others); on-line almost all days all months, minor exceptions
  • 21934: like #21773, a fairly poor well for the Sanish; note, both #21773 and #21934 are Three Forks wells;
  • 24557: very good production in the first few months (not quite as good as 19517); then the typical decline; on-line almost the entire time
