$this->bbcode_second_pass_quote('ROCKMAN', 'D')C - Same stats for Chesapeake: during May 2012 they put 16 wells on production. Only 5 were single well leases and during the first 12 months they produced 59k, 67k, 72k, 96k and 105k bbls of oil. During the first 12 months those 16 wells produced an average of 38.9k bbls of oil each.
Still haven't found a population of recent wells that look as though they'll average anywhere close to 300k bbls of oil. Guess I'll keep looking. Those press releases couldn't be misleading folks that badly, could they?
Hi Rockman,
It is quite hard nailing this down because of the way Texas reports its data, the 30 year EUR for the average well profile I developed (based on the Eagleford 2 field) is 232 kb not 300 kb, 20 year EUR is 226 kb, and 15 year is 221 kb, first 3 years output for the average well is 172 kb. I realize that if 4 wells are on a lease it is highly unlikely that their output would be the same, but as we are looking for the average anyway we can treat it that way to find our "average" well as long as all 4 wells start production at about the same time (within a month).
My average well profile is based on 170 wells which started producing between Dec 2010 and April 2012, data was collected in Feb 2013 so the more recent wells have only 9 months of data, 133 wells had 12 months or more of production and the average 12 month output of these 133 wells was 108 kb. I have not gone back to reevaluate this "average well", but it is all based on data I obtained from the TRRC.
My only complaint about the TRRC is the aggregate output data, I think the EIA estimates for statewide TX C+C for the period of May 2012 to May 2013 is much better than the TRRC estimates. For individual leases, well counts, etc, the EIA is not useful at all and the TRRC is the best that we have.
