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.
The characteristics of the Harald field reservoir are as follows.[1]

Production
An 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.
