Deep Panuke Project Description - Encana

2.2.2 Subsea Wells and FlowlinesThe initial development well program will consist of re-completing four existing production wells (H-08, M-79A, F-70, and D-41), drilling one new injection well (D-70) in Margaree (EL 2387), and onenew production well (H-99) in Panuke (PL 2902). Up to three new production wells could be drilledafter first gas in Cohasset (PL 2901), Deep Cohasset (SDL 2255H), Panuke (PL 2902) or Margaree (EL2387).All wells will be completed with horizontal subsea trees and tied back to the MOPU with individualsubsea flowlines and control umbilicals. All subsea flowlines and control umbilicals will be trenchedand buried.2.2.3 Export PipelineEnCana proposes to transport sales product via a subsea pipeline from the offshore processing facility toone of two delivery points:• Goldboro, Nova Scotia (M&NP Option) to an interconnection with M&NP; or• SOEP 660 mm [26 inch] pipeline tie-in (SOEP Subsea Option) at a close point on the pipelineroute.The Deep Panuke export pipeline will have a capacity of 8.5 x 10 6 m 3 /d [300 MMscfd] at meanenvironmental conditions. The proposed routes of the export pipeline will minimize its footprint byusing existing pipeline and flowline corridors where practical. The pipeline details for both options arepresented in Table 2.1. All values are approximate.Table 2.1Export PipelinePipeline Diameter Pipeline Length (km)Pipeline Phases(mm [inch])M&NP Option 560 [22] 176 (includingSingle phaseapproximately 3 kmonshore)SOEP Subsea Option 510 [20] 15 Multi-phaseFor the SOEP Subsea Option, the export pipeline tie-in point will be at a subsea location. The tie-infacility will likely consist of a hot tap tie-in assembly and a valve tie-in assembly. Each assembly will besecured to the seabed using piles and surrounded by a subsea protection structure. Final processing ofthe Deep Panuke fluids will be done by SOEP at the onshore plants near Goldboro, NS and PointTupper, NS.Deep Panuke Volume 4 (Environmental Assessment Report)• November 2006 2-5
