Hansa holds a 19% interest in Block 47/14b (Licence P614) which contains the Juliet field in the UK Southern North Sea. Production start-up was achieved in early January 2014. The Juliet development comprises two subsea horizontal wells tied-back to the Pickerill A platform and production is exported to the Theddlethorpe gas processing terminal in Lincolnshire. Hansa earned an interest in Juliet through a farm-in process in 2010 and project sanction was achieved in June 2012.
“Our participation in the Juliet development underpinned Hansa as a meaningful player in the basin.”
The Juliet field is located in the UK Southern North Sea 39km due east from the Humberside estuary in 59m of water. The field is located approximately 9km to the south of the Amethyst gas field.
Block 47/14b (Licence P614) was originally awarded in 1987 and following various changes in licence interests, ENGIE, as operator, together with First Oil, drilled the first well on the licence, 47/14b-10, in December 2008 which led to the Juliet discovery. The discovery was deemed commercial and ENGIE immediately embarked on development planning in 2009. In September 2010 Hansa acquired a 19% equity interest from First Oil in Block 47/14b in return for a development carry. In December 2015, ENGIE exercised its right under the joint operating agreement to forfeit First Oil’s 19% interest following default by First Oil.
The current ownership of the licence interests are:
ENGIE (operator) 81.00%
Hansa Hydrocarbons 19.00%

The Juliet structure lies on the edge of the south west margin of the Southern North Sea gas basin. The reservoir sands consist of the gas bearing Leman sandstone which is the major producing gas reservoir in the basin. The closest producing field from this reservoir is the Amethyst East field immediately to the east.
The discovery well was drilled near the crest of the structure in the west of the field. Juliet is principally a dip closed structure but relies on fault seal for closure to the south-west, east and north-east. Top seal is provided by the overlying Zechstein evaporites. The discovery well encountered high quality Aeolian sands with excellent porosity and permeability characteristics which delivered 38 mmscfd on a constrained well test from a 20 ft interval.
The Juliet Field Development was sanctioned in June 2012 with first gas achieved in January 2014. The development comprises two horizontal subsea wells tied back by a 22km 12-inch diameter export pipeline and control umbilical to the Pickerill A platform operated by Perenco UK Ltd.
The first well was spudded in February 2013 with the Noble Ronald Hoope jack-up drilling rig and completed in May. Upon clean-up a constrained flow rate of 63 million standard cubic feet per day was achieved. The second well was spudded in October 2013 with the GSF Monarch jack-up drilling rig and will be brought into production in Q1 2014. The topsides modifications performed on the Pickerill A platform include installation of metering systems, an emergency shutdown valve and an eductor to mitigate against back-out of Pickerill gas.
Production is transported through existing infrastructure from Pickerill A to the ConocoPhillips operated Theddlethorpe terminal on the Lincolnshire coast.
Gas enters the National Transmission System following treatment at Theddlethorpe. Hansa’s share of gas production is sold to RWE Supply and Trading GmbH and condensate production is sold to Phillips66 Limited.
