A couple of arguments are often posted here on peakoil.com as reasons as to why peak oil is imminent. One is that private oil companies haven’t been investing in finding new oil because there is “little new oil to find.”
Another is that depletion rates in the range of 7-8% (thinking of the recent article on Oil Drum) will be indicative of the depletion rates going forward.
The following article posts some good counter arguments to those claims. It provides some interesting tidbits on why oil companies have acted the way they have. More generally the author also tackles the issue of whether or not we are near a crisis of “peak oil”. On this last point I think the author doesn’t make a very strong case especially considering his tacit admission that the industry may be under-equipped and under-manned to respond to demand. But nonetheless he makes some good points that require consideration.
Four main points are argued in his article:
Lack of new exploration has been due to oil companies’ concentration on harvesting known assets. Until very recently there has always been ample spare capacity in the world. This has led private companies to pursue the Holy Grail of Return on Capital Employed targets – getting cash out of known assets and not spending cash on finding more fields which would sit idle.
Mature field decline rates are a concern but are a result of a combination of several factors and do not indicate overall worldwide resource stress nor do they act as an indicator of future decline rates. Most fields that are experiencing high decline rates are resources that have been exploited without restriction. (ie. Little government intervention) Those non-private fields (such as in Mexico) that have experienced high decline rates are due to the severe siphoning off of cash flow thus diverting resources necessary to sustain production.
New legacy assets take time to come online and until recently were not pursued due to internal criteria which resulted only in the most profitable (real rates of return in excess of 7 to 8 percent) projects being pursued.
Manpower (and other logistical) constraints will be the biggest barrier to rapidly building up production capacity.
An interesting read..
