ATP Oil & Gas Corporation announced an increase in its estimated year-end 2011 proved and probable pre-tax PV-10 value to $7.3 billion based on SEC pricing, up 52 percent from $4.8 billion at year-end 2010. ATP also provided an update on production for full-year 2011 which averaged an estimated 24.6 thousand barrels per day (MBoe/d), an increase of 17 percent over 2010.
Reserves – ATP estimates year-end 2011 proved reserves of 118.9 MMBoe compared to 126.1 MMBoe at year-end 2010. ATP estimates proved and probable reserves of 194.4 MMBoe at year-end 2011, compared to 211.3 MMBoe at year-end 2010. The changes were primarily a result of production of 9.0 MMBoe in 2011 and revisions to oil and gas reserves. On a Boe basis, ATP estimates that oil and natural gas liquids (NGLs) represent 66 percent of its year-end 2011 proved reserves and 65 percent of proved and probable reserves, compared to 60 percent and 59 percent, respectively, at year-end 2010.
ATP estimates a year-end 2011 SEC pre-tax PV-10 value of $4.2 billion for its proved reserves and $7.3 billion for its proved and probable reserves, compared to $2.6 billion and $4.8 billion, respectively, at year-end 2010. This increase is primarily a result of pricing, but other factors include timing and an increase in oil and NGL reserves.
Since independent reservoir engineers are finalizing estimates of ATP's oil and natural gas reserves for year-end 2011, ATP will issue its final reserve amounts utilizing SEC pricing and reconciliation in conjunction with filing its Form 10-K, anticipated in March 2012.
Production - ATP's production in the fourth quarter 2011 averaged 24.8 MBoe/d compared to 24.2 MBoe/d in the third quarter 2011. The fourth quarter average benefited from a 1.4 MBoe/d recognition of royalty relief related to 2010 production. Not including this benefit, average production in the fourth quarter was 23.4 MBoe/d, of which 70 percent was oil, compared to 69 percent in the third quarter 2011. ATP intends to conduct the previously announced sleeve shift at the Mississippi Canyon (MC) 941 A-1 well in the first quarter 2012 after production is established at the MC 942 #2 well. This sleeve shift had previously been scheduled in the fourth quarter of 2011. ATP estimates that opening the sleeve in the MC 941 A-1 well will increase production by 1.5 MBoe/d.
ATP anticipates an increase in production from the completion of the MC 942 #2 well during the first quarter 2012 and an increase later in the year with the installation of the pipeline for the two Clipper wells that were completed and tested in 2011. The installation of the Clipper pipeline is scheduled to begin in the third quarter 2012 with production expected in the late third quarter/early fourth quarter 2012.
