Chevron’s deepwater assets highlight value of dual-gradient drilling

The “un-drillable” is becoming drillable by using dual-gradient drilling (DGD) to remove the impact of water depth. Dale Straub, Senior Drilling Advisor at Chevron, discussed the impact of DGD on the number of casing strings and completion opportunities at the 2014 IADC DGD Workshop on 7 April in Madrid. In this exclusive video, Mr Straub provides an update on Chevron’s DGD program in the US Gulf of Mexico.
