THE SEDIMENTS DESCRIBED AS THE NIOBRARA FORMATION WERE DEPOSITED IN THE DEEPER PORTION OF THE WESTERN INTERIOR SEAWAY DURING THE LATE CRETACEOUS PERIOD.
Extending from Canada into New Mexico, the Niobrara is represented in northeastern Colorado by a calcareous shale with high-in-place organic content similar to Texas' Austin Chalk. This brittle marl is highly fractured in some areas and has been a prolific producer of oil when this fractured reservoir has been developed using horizontal drilling technology. Carrizo's land position is concentrated in Weld and Morgan Counties where Niobrara wells produce oil with little associated gas.
PLANNED 2017 ACTIVITY
No drilling or completion activity is currently planned during 2017
