Oil &  Gas Journal: Shell starts gas production from deepwater Coulomb development in Gulf of Mexico 

By OGJ editors

HOUSTON, July 12 -- Shell Exploration & Production Co. June 23 began producing natural gas from its Coulomb development on Mississippi Canyon blocks 657 and 613 in the deepwater Gulf of Mexico. The project comprises the two deepest wells in the world in terms of water depth, the company reported.

The Coulomb wells are tied back via a 27 mile flowline to the BP PLC-Shell Na Kika floating development system on MC Block 474. The Coulomb C-2 well is currently producing about 65 MMcfd of gas. Combined, both the C-2 and C-3 wells are capable of producing about 100 MMcfd of gas, Shell said.

Shell holds 100% interest in the C-2 well, and Petrobras America Inc. is one third partner in the C-3 well.

The C-2 well May 2 became the world's deepest water depth completion in 7,565 ft of water. The C-3 well was then drilled in 7,570 ft of water May 19.
