Investment in the field is roughly NOK 800 million (about $90 million), including drilling and completion of four production wells and one water injector as well as engineering work. Oil from this field is produced via the FPSO Petrojarl I. At the end of 2003, 5 production wells, 1 gas injection well and 1 water injection well were in operation. The wells are connected to the FPSO with seven flexible risers. Production in 2003 was 1.686 million Sm3 (10.6 million bbls), or approximately 4,600 Sm3/day (29,000 bbls) – 12% more than expected for the year. Petrojarl I produces on behalf of Statoil, the formal operator of the field. The contract was signed in September 2000 and production was originally planned until 2005. Activities are now planned to last to 2007. Normal manning is 43 persons, of which 36 are regular PGS Production crew. Statoil has one representative onboard. Since Jauary 1st 2003, produced water has been reinjected into the reservoir. When the water injection system is not operative, produced water is cleaned in hydro-cyclones before discharge to sea. Waste is shipped to shore and taken care of by SAR via the Statoil Dusavik Base. The produced oil is transported by the tanker Petroskald, another PGS Production vessel. With today’s production rate (as of January 2004), oil is offloaded to tanker approx. every fifth day. The oil’s shipping destination depends on who owns the cargo. In 2003 most trips went to Rotterdam and Kalundborg. The FPSO Petrojarl I is a floating production facility complete with riser reception, choke manifold, crude processing, gas compression, water injection facilities and oil storage. Today, the Petrojarl I is equipped with reception slots for altogether eight flexible risers. She has a derrick above the moonpool, as originally the ship was equipped for producing oil from one well, through either one flexible or one rigid riser. Petrojarl I is currently deployed on the Glitne field in the Norwegian North Sea on a multi-year contract for Statoil. Since commencing operation in 1986, she has serviced ten fields and conducted over 1,300 offloadings to shuttle tankers without a reportable environmental incident.
