Project Profile
Value: Undisclosed
Location: Located 250km southeast of Halifax, Nova Scotia, Canada
Initial Production: 200mmcf/d
Start-up Year: 2013
The Deep Panuke gas field is located 250km south east of Halifax, Nova Scotia, Canada. The wells tap into the natural gas reservoirs in the carbonate reef located underneath the original Cohasset-Panuke oilfield - Canada\'s first offshore project - which ceased production in late 1999. The life of the field is estimated to be between eight and 18 years.
The area was first explored by Shell in 1986 and in the 1990s by Encana. Since 1999, the operator has drilled four wells into the Deep Panuke structure, 3,400-3,500m below the now depleted Panuke oilfield. The PP-C3 well discovered 225ft of net pay, producing at a rate of 55 million cubic feet of gas per day. The first appraisal well, PI-1 b, showed 110ft of net pay, while the second appraisal well, H-08, flowed at an average rate of more than 50 million cubic feet per day of natural gas – the maximum capacity of the testing equipment - during a three-day test. The third appraisal well, M-79A, was drilled offshore about 3km east of the Panuke platform. The horizontal sidetrack encountered 360ft of net pay. The natural gas project was given the go ahead in February 2001.
Acergy was awarded a US$195m engineering, procurement and construction contract for installation of 17km of flowlines and umbilicals. The subsea equipment will connect the production wells to the FPSO. Acergy is using its construction vessels Acergy Falcon and Acergy Discovery to carry out the pipeline installation works.
Acergy subcontracted CRC-Evans/Global Pipelines to carry out onshore double jointing and offshore welding of the production lines. Claxton Engineering Services, a unit of Aceton, was awarded a US$1.9m contract for supplying and installing a 5,000psi riser system at the field. The riser system includes 24in diameter riser joints, connectors, umbilicals and a power unit. 2H Offshore, another unit of Aceton, provided riser analysis for the project.
Dominion Diving carried out Multi Beam and ROV surveys for placement of the PFC at the field. Under a $14.4m contract, Tideway carried out stone filling on the seabed to stabilise the PFC and protect the pipelines from the high waves and strong seabed currents. Tideway used a new Inclined Fallpipe System and its Tideway Rollingstone vessel for the filling.
M&A Engineering was contracted to supply specialised pipe machining equipment for the field. McNally International carried out marine and onshore works for the shore access of the project. It subcontracted Bezemer to supply 500mt beach pull for the project.
