$this->bbcode_second_pass_quote('ROCKMAN', 'T')he question came the other day after the announcement of the latest DW GOM discovery: how many new fields in the future. I don't know but here is the count for the number of fields that began producing during the last 10 years:
2002 - 13
2003 - 8
2004 - 13
2005 - 7
2006 - 15
2007 - 7
2008 - 5
2009 - 8
2010 - 4
2011 - 3
2012 - 6
Not absolute but looks like the rate is dropping. The question was if we could expect 20 new fields coming to production in the next 12 months. Doesn't look likely. OTOH there are many undrilled leases and currently over 1,800 approved drill permits. But it cuts both ways: while the learning curve goes up there are fewer fields to discover. And, though not perfect, companies try to drill the best looking prospects first. But also know it's not uncommon to permit more wells than one eventually drills. It can take a couple of years to get a permit so you apply for every possibility.
But we should still have a lot of oil developed out there for at least the next 10 -15 years IMHO.
Over the last 5 years the rate seems pretty steady, if that is correct and it remains steady then we might expect about 25 new fields to come on line over the next 5 years, or about 5 each year. Let's assume each field on average produces at a maximum rate of 25 kb/d, that would give us 125 kb/d which would offset the likely 10 % decline rate of fields already in production so that production would remain flat.
If the average decline rate of existing production is 20 % (similar to North Sea average decline rates) and the 5 new fields per year is correct, then these fields would need to be about 50 kb/d to offset declines from existing production.
Note that if we assume that 90 % of the current GOM output is from the 89 fields that came online in the last 10 years (a WAG), then the average output of those 89 fields is about 13 kb/d.
We also need to keep in mind the long lead time needed for these projects, if 10 years is about right then the run up in oil prices from 2005 to 2008 might lead to an increase in fields brought online between 2015 and 2018.
