Petro-Canada Terra Nova

PetroCanada Terra Nova

Canada Blocks Graben, East Flank, Far East

Landmark: World’s first major project in iceberg laden waters

The Terra Nova project is located in the Jeanne d’Arc Basin, 220 miles (350 km) east-southeast of St. John’s, Newfoundland. It is comprised of three geological blocks: Graben, East Flank and Far East. Phases I and II consist of 24 wells drilled through seven subsea templates and one spare subsea tree. The subsea wells are linked to a Floating Production Storage and Offloading (FPSO) facility. Subsea layout consists of production wells feeding into manifolds, which in turn are connected by flexible flowlines to a riser base, and then to the FPSO via a riser system.

This project was executed as a result of an alliance between Petro-Canada, Coflexip Stena Offshore, ShawMont Brown and Root, Halliburton Energy Services, PCL Industrial Constructors Inc, Doris ConPro Limited and FMC. The wells are located in dredged-out trenches called glory holes to protect them from the impact of icebergs that occasionally scour the area.
