It has been said that any well taken off-line for any significant period of time will show an increase in production once it's brought back on status. ("Significant period of time" in the oil patch is defined as about 3 - 8 months for purpose of this discussion.)
Here's an example of Mother Nature's inefficiency.
Note the peak production of this well after being fracked in the month of May, 2009: 11,976 bbls, which works out to 14,279 barrels for the full 31 days of the month (in fact, it would have been slightly less due to the severe decline rate of the Bakken).
After being fracked in 2009, after Mother Nature "shut-in" this well for a gazillion years, it's production was about 14,000 bbls in that first month, after which its production plunged to 2,000 bbls/month only six or seven months later.
However, a few years later, this well was taken off-line (not for a gazillion years as Mother Nature had done earlier) but for only a few months -- about six months in fact. After being taken off-line for only six months, look at the production in May, 2013: 14,798 bbls (for a 31-day month that would extrapolate to 15,291 bbls of crude oil.
[Just for the fun of it, boe:After being fracked in early 2009, this well was down to about 2,000 bbl of crude oil/month by the seventh month.
May, 2009: 2,365 + 14,279 = 16,644 boe
May, 2013: 5,002 + 15,291 = 20,293 boe]
Note, after this well was taken off-line for six months, it's production surged, and remained well above 2,000 bbls of crude oil/month for the next two years, in fact jumping to over 4,000 bbls in two consecutive months.
For newbies: this is all done with tongue in cheek. Pay no attention to this. It was just something that caught my attention: how much production in a Bakken well can improve by just taking it off-line for a few months. Of course, it begs a question. In fact, it begs a lot of questions.
