Project Profile
Location: Gulf of Hammamet
Production: 2,000 bopd
2P reserves: 11.5 million barrels of oil
Water depth: 75m
Area: 420 km2
Start-up year: November 2006
The Oudna oil field is located in the Gulf of Hammamet, 80km off the northern eastern coast of Tunisia. Operated by Lundin Petroleum, the field came on stream in November 2006. The field is currently producing at the rate of 2,000 barrels of oil a day (bopd).
Oudna was discovered by Shell in 1978 with the drilling of the Oudna-1 well. The well was drilled to a depth of 1,600m and flowed at the rate of 7,000 bopd. Proven and probable reserves of the field are estimated at 11.5 million barrels of oil. The crude oil has an API of 41.5° and sulphur content of 0.24%.
A 3-D seismic survey carried out in 1998 indicated the geometry as a large tilted fault block. The development plan for the field was approved by the government in 2004. The plan was later revised in 2005. Drilling activities at the field commenced in 2006. In February 2006, the Oudna production well was drilled to a depth of 300m. It was drilled, tested and completed by the Pride Venezuela semi-submersible drilling rig. The injection well was also drilled by the same rig. Sinochem\'s subsidiary Atlantis Holding Norway was involved in the development of the field.
In September 2005, Petrofac was awarded a contract to provide engineering, procurement and project management services for the field. Petrofac was responsible for providing the subsea and mooring equipment required for carrying out modifications of the Ikdam FPSO. Installation of the FPSO at the field was also part of the contract. Aker Kvaerner was awarded a US$14 million subsea equipment installation contract in January 2006. The scope of work included installation of the mooring system, risers and umbilicals and hook up to the FPSO.
Bollfilter supplied its Boll BFD-P duplex filters for installation on the FPSO. The filters helped in removing particulates present in the crude oil. The particulates were damaging the high pressure pumps used at the field.
RPI Rubber and Plastic Industries Scotland supplied low friction polyurethane risers for the field. Petro Consultants provided consulting services during conversion of the Ikdam FPSO. Malta Shipyards was awarded the upgrade contract for the FPSO. It was also responsible for engineering, procurement, construction and installation of the FPSO.
