In 2015, ONE completed the acquisition of a 50% operated interest in the Sean field, located in the UK’s Southern North Sea.
The Sean field is located in UKCS blocks 49/24e, 49/25a and 49/30a, some 70 km northeast of the East Anglia coast. Gas from the Sean field is evacuated through a dedicated 107 km 30” pipeline to the Bacton terminal.
Sean comprises excellent reservoir quality. The Sean field produces gas via 2 platforms, Sean Papa and Sean Romeo. Sean Papa comprises 2 bridge-linked platforms: a wellhead and compression platform (PD) and a production and accommodation platform (PP). Sean Romeo is connected to Sean Papa through a 20” duplex line. Per the effective date of the acquisition (1 July 2014), ONE’s production increased from ca 11 kboe/d to ca 20 kboe/d. In mid 2017 an infill well will target a partially drained part of the Sean field, increasing production and reserves.
