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
