Comments (disclaimer -- I have no background or formal training in the oil and gas industry; what follows is simply my opinion; many will disagree; no one should make any decisions based on these comments; it is simply idle chatter; if this information is important to you, you should visit more credible sources):
This was my
original description of the Round Prairie oil field:
Round Prairie is about a 20-section oil field west of Williston,
right on the Montana state line. It is all prairie. It looks like the
field is owned by EOG. The wells are mediocre but they were probably
completed before EOG started using newer completion techniques. They
should all hit 100,000 bbls in three or four years (some already have);
some might take a bit longer. But they should all pay for themselves,
and are all good enough to ensure more drilling in this area. With the
exception of one well, they are all producing between 1,000 and 6,000
bbls/month.
That, of course, was written before the slump in oil prices. It appears the entire field is "held by production," so there won't be any hurry to initiate new drilling until prices recover -- and because this is not the best spot in the Bakken, one would not expect new drilling until oil prices are significantly higher (back in the $80-range, at least). Again, remember this is simply opinion, idle chatter. I have nothing to base this on except my following the Bakken for several years.
A typical well in a mediocre field will probably produce around 400,000 bbls of oil over its 20 - 40-year-lifespan
assuming oil prices support continued operation of the well. The total production of a well is referred to as the estimated ultimate recovery (EUR).
The biggest expense for this well, now, is probably getting rid of the water.
This well is producing more water than oil right now and all that water has to be trucked out and brought to a saltwater disposal well.
The well is capturing all its natural gas; no natural gas is being flared.
If the price of oil returns to the $100-range, a well like this one would probably be re-worked several times in its life-time.
It's hard to say whether this well will be re-fracked. Its initial fracking was a pretty impressive 48 stages using almost 10 million pounds of sand. It was also a fairly deep well: the middle Bakken about 10,500 feet deep vertically. So, a relatively expensive well.
The biggest unknown is whether this well will be choked back due to the slump in oil prices and whether it will be shut in if the slump in the price of oil persists.
