Cement Bond Log - Production Casing

Pressure Testing Production casing is pressure tested to above maximum treating pressure prior to perforating. Bradenhead pressure between production and surface casing is continuously monitored during fracturing operations. A change in the Bradenhead pressure during the fracturing operations may shut down the operation and indicate wellbore issues. Chevron has not had a Bradenhead pressure indicated issue in the Piceance Basin since starting fracturing operations in 2006. In the Piceance Basin, Chevron has had one production casing not pressure tested prior to fracturing that required repair. © 2010 Chevron
