ExxonMobil starts production at Julia oilfield in the Gulf of Mexico

Oilfield Technology,

Exxon Mobil Corporation has announced that oil production has commenced on the Julia oilfield in the Gulf of Mexico, under budget and ahead of schedule. The first production well is now online and a second well will start production in the coming weeks.

The Julia development is located approximately 265 miles southwest of New Orleans in water depths of more than 7000 ft. The initial development phase uses subsea tie-backs to the Chevron-operated Jack/St. Malo production facility, which reduces the need for additional infrastructure and enhancing capital efficiency. Technology has also played a key role in the Julia development including the use of subsea pumps that have one of the deepest applications and highest design pressures in the industry to date.

“Successful deepwater developments like Julia, located more than 30 000 ft below the ocean’s surface, benefit from ExxonMobil’s disciplined project execution capabilities and commitment to developing quality resources using advanced technology,” said Neil W. Duffin, president of ExxonMobil Development Company.

Additional projects

The Maersk Viking drillship is currently drilling a third well, which is expected to come online in early 2017. Production results will assist in the evaluation of additional wells included in the initial development phase, which has a design capacity of 34 000 bpd.

“This initial production will provide ExxonMobil with insight into the potential future development of the reservoir,” said Duffin.

Discovered in 2007, the Julia field comprises five leases in the ultra-deepwater Walker Ridge area of the Gulf of Mexico. ExxonMobil, the operator, and Statoil Gulf of Mexico LLC each hold a 50% interest in the Julia unit. Over the past decade, ExxonMobil has drilled 187 deepwater wells worldwide in water ranging from 2100 ft to 8700 ft.

ExxonMobil looks set to start up 10 new Upstream projects in 2016 and 2017, adding 450 000 boe/d of working-interest production capacity. The company is enhancing resource value through production optimisation, technology application and cost management.
