Petrobras has cancelled a process to contract five new ultra deep-water drilling rigs, due to the pre-salt’s strong resource quality, which means fewer wells are required. The company cited higher well productivity in the pre-salt Santos basin as a reason for the cancellation. Higher well productivity will require fewer wells overall. The rigs, which were […]

Onshore Permits All major states require the filing of a drilling permit before the drilling of a well. The filing for the permit is usually one of the last steps taken before drilling. Before the permit is filed for, companies incur significant expenses, including land costs, legal fees, and geological expenses, and, at that time, […]

This lag is usually around a quarter, simply due to logistical issues of moving both the rig and completion equipment. However, in the Haynesville, the backlog expanded to […]
