Carrizo
Leases
As of December 31, 2004, Carrizo held a
total of 30,000 net acres in the Barnett Shale. Approximately
4,000 net acres were within the mature “Core” area which has
better defined production characteristics due to the large number
of Barnett producing wells (over 3,000 at year-end). Carrizo
had approximately 17,000 net acres in the Tier 1 area at year-end.
This area has fewer Barnett Shale wells (under 300), but has
all of the characteristics required for very successful development.
The approximate 9,000 acres outside of Tier 1 is gas-bearing
and highly prospective, but has very few (less than 25) Barnett
Shale wells drilled to-date.
