ABERDEEN, UK – Dana Petroleum has submitted a draft field development plan and environmental statement for the Platypus gas field in the UK southern North Sea.
According to partner Parkmead, mid-case technical recoverable reserves from the field are 105 bcf, with estimated peak production through the planned facilities of 47 MMcf/d.
Platypus is in blocks 47/5b and 48/1a, 18 km (11.2 mi) northwest of the West Sole gas field and 15 km (9.3 mi) southwest of the Babbage field.
It was discovered in 2010 and successfully appraised with a horizontal well in 2012 which flow tested at 27 MMcf/d.
Dana plans two development wells connected to a subsea manifold, with gas exported to the Perenco-operated Cleeton Wellhead (CW) platform via a 23-km (14.3-mi) pipeline.
Controls will be provided from Cleeton via a subsea control umbilical installed with the pipeline. Produced fluids will arrive at the Cleeton complex facilities before being routed to the Dimlington terminal on the Lincolnshire coast of eastern England for separation and processing.
The CW platform is bridge-linked to the manned Cleeton CP platform. Other installations and gas fields connected to Cleeton are Ravenspurn, Neptune, Minerva, Wollaston, and Whittle.
According to Dana, tenders should go out shortly for the subsea pipeline and facilities EPCI, umbilical supply and controls contracts, with project sanction likely to follow next spring. First gas is scheduled for 1Q 2022.
The two Platypus development wells, of similar design, will be drilled in 40 m (131 ft) of water to a TD of around 3,109 m (10,200 ft).
There could be a further 51 bcf recoverable at the Platypus East prospect. Results from early reservoir monitoring at Platypus will provide relevant additional data prior to spudding of the Platypus East well.
