Maersk Oil said March 31 that production began on budget from the new Tyra Southeast-B unmanned platform. Tyra Southeast-B is expected to add 50 MMboe of reserves to Danish production for the next 30 years, the company added.

The Ensco 72 drilling rig drilled the area’s first well in December 2014. This well alone is expected to produce 2,600 boe/d. A total of eight to 12 horizontal wells are planned to be drilled from 2015 to 2017. They will each be about 6 km long, Maersk added.

Tyra is 220 km off the west coast of Denmark. It is expected to produce about 20 MMbbl of oil and 170 cf of gas. It is expected to produce 50 MMboe of combined reserves and resources. Peak production of 20 Mboe/d is expected in 2017.

The total investment in Tyra is 4.5 billion Danish kroner. It includes the 4,700-tonne platform, pipelines and well drilling. The investment is the largest made by Danish Underground Consortium (DUC) since the approval of the Phase IV development of Halfdan in 2007.

Danish contractor Bladt Industries A/S built the platform’s jacket and topside.

DUC is the partnership between A.P. Møller - Mærsk (31.2%), Shell (36.8%), Nordsøfonden (20%) and Chevron (12.0%).
