Weil ich das gerade gelesen habe, dachte ich es sei wert, hier mal gepostet zu werden. Aus dem 2006 Jahresbericht von Southwestern Energy:
Fayetteville Shale Play
Since we announced the Fayetteville Shale play in August 2004, we have made
significant progress in expanding and delineating the known boundaries of
the play, discovered better well completion methods and laid the foundation for
a large, multi-year drilling program.
At December 31, 2006, we held approximately 892,000 net acres
in the Fayetteville Shale play. Through year-end 2006, we have established
production from the Fayetteville Shale over an area which represents
approximately 45% of our total acreage position, covering 28 separate pilot
areas located in eight counties in Arkansas.
Our development efforts in the Fayetteville Shale continued to
accelerate during 2006. The creation of our own drilling company allowed us to
go from three rigs running in the Fayetteville Shale at the beginning of the year
to 19 rigs running at year-end. This allowed us to spud a total of 196 wells in
2006, compared to 67 wells in 2005 and 21 wells in 2004.
Our results to date indicate that the optimal development of our
acreage will primarily require horizontal wells. After initially utilizing nitrogen foam
fluid systems to hydraulically fracture our wells, in 2006 we began using
slickwater and crosslinked gel systems to complete our wells, which have
improved production performance. At year-end 2006, 172 wells had been
drilled and completed, including 118 horizontal wells, 92 of which were fracture
stimulated using either slickwater or crosslinked gel fluids. As a result, our
production volumes from the project grew from approximately 9 MMcf per day
at the beginning of 2006 to near 100 MMcf per day at year-end, resulting in
net production from the play of 11.8 Bcf in 2006, compared to 1.8 Bcf in 2005
and 0.1 Bcf in 2004. Total proved gas reserves booked in the play also grew
to 300 Bcf at year-end 2006, compared to 101 Bcf at year-end 2005 and
7.5 Bcf at year-end 2004. We currently estimate that the average ultimate gross
production for the horizontal wells stimulated using either slickwater or
crosslinked gel fluids will be 1.3 to 1.5 Bcf per well.
We believe the Fayetteville Shale play has the potential to deliver
substantial growth in reserves and production for many years. In 2007, we plan
to invest $875 million in our Fayetteville Shale play, which includes drilling between
400 and 450 horizontal wells and shooting 3-D seismic over a large portion of
our acreage. We expect that our capital program will generate a significant
increase in our production volumes from the play, which could reach as high as
300 MMcf per day by the end of 2007 and should result in net production of
45.0 to 50.0 Bcf for the year.
