Repsol to develop satellite fields off Spain
By OGJ editors
HOUSTON, Feb. 24 -- Repsol Investigaciones Petroliferas SA has let a lump-sum contract to Technip for subsea work to develop two Casablanca satellite oil fields 50 km off the eastern coast of Spain in the Mediterranean Sea, Technip reported.
A Repsol group made the Montanazo D-5 and Lubina-1 discoveries northeast of Casablanca and off Tarragona in mid-2009.
Montanazo, drilled to 2,354 m in 736 m of water, tested at 3,800 b/d of 32° gravity oil. Lubina, drilled to 2,439 m in 663 m of water 4 km north of Montanazo, made 3,700 b/d of 31.5° gravity oil. Repsol said each could produce 5-7 years, quadrupling Spain’s then-existing 2,000 b/d of oil production.
Technip’s scope includes engineering, supply, installation, and precommissioning of an 11-km flexible pipeline system to connect two production wells to the Casablanca platform, installed in 1981, which already handles oil from Boqueron, Rodaballo, Chipiron, and Casablanca fields.
Offshore installation is scheduled for first-half 2011 using the Deep Constructor, a Technip deepwater construction vessels.
This pipeline system will include a riser, a flowline, and two short sections of pipe to connect subsea structures.
In addition, Technip will install a pumping manifold and umbilicals. The flexible pipelines and umbilicals will be trenched to protect fishing lines, Technip said.
All flexible pipelines will be fabricated at Technip’s plant in Le Trait, France.
