Gas/condensate discovery northeast of the Martin Linge field (30/4-3S)
The well was drilled in the northeast part of the Martin Linge field in the North Sea. The objective of the well was to prove petroleum in Middle Jurassic reservoir rocks (Brent group). The well encountered gas and condensate in the Tarbert, Ness and Etive formations in the Brent group. Reservoir quality was good. Preliminary estimations of the size of the discovery are between 2 and 11 million standard cubic metres (Sm3) of recoverable oil equivalents.
Extensive data acquisition and sampling have been carried out. The well was formation-tested. The maximum production rate was 2.4 million standard cubic metres (Sm3) of gas/flow day through a 48/64-inch nozzle opening. The well has added additional resources to the Martin Linge development and was completed with the objective of putting the well into production at start-up of the field. 30/4-3 S is the fourth exploration well in production licence 043. The licence was awarded in 1976.
The well was drilled to a vertical and measured depth of 4,134 metres and 4,581 metres below the sea surface, respectively, and was terminated in the Dunlin group in the Early Jurassic. Water depth is 115 metres. The well was drilled with the Maersk Intrepid drilling facility.
