The Harald field is a gas and associated condensate production field in the Danish sector of the central North Sea. Production of gas and liquids started in 1997, and peak gas was in 1998. The Lulita field is a satellite of the Harald field.

Production
editAn 8-inch multi-phase pipeline transports fluids from the Norwegian Trym gas field to Harald A for processing.[1]
Production of the Harald field is by gas expansion, plus water influx.[1]
Harald acts as the processing facility for the Lulita field.[1]
The gas and condensate production profile of the Harald field is as shown in the tables.

The Lulita field
editThe Lulita field is a satellite of the Harald field. The accumulation is oil with a gas cap, and is a structural fault trap in a Middle Jurassic sandstone. The reservoir is at a depth of 3,525 m, with a field delineation of 4 km2.[1] The field was discovered in 1992 and came onstream in 1998. The production is based on natural depletion. The reservoir is produced through two subsea wells in a water depth of 65 m, flowlines deliver the wellhead fluid to the Harald installation where dedicated equipment produces oil, gas and water streams.[1]
The oil and gas production profile of the Lulita field is as shown in the tables.
