New reserves in an old field, the Niobrara/ Codell resource plays in the Wattenberg Field, Denver Basin, Colorado

摘要

The Niobrara Formation and Codell Sandstone are one of nine horizons that are productive in the giant Wattenberg Field area (GWA) of Colorado. GWA covers approximately 3200 square miles. The field was discovered in 1970 (J Sandstone) and the first significant Codell production from vertical wells was established in 1981 followed by Niobrara production in 1986. Horizontal Niobrara/Codell drilling began in the field in 2009.
