This engineering study on the use of dual gradient drilling for top-hole applications will potentially improve safety in handling some of the shallow below seafloor drilling hazards encountered in the Gulf of Mexico. These hazards include, but are not limited to, methane hydrates, shallow gas, and shallow water flows. This technology could also minimize the environmental impact of the current 'pump and dump' practice while drilling conductor and surface holes.

Project Description

Compare the use of a slim high-pressure riser system and a surface BOP to the conventional subsea BOP and large diameter low-pressure drilling riser in the deepwater Gulf of Mexico region.
