Aviat is a shallow gas field located in Block 22/7A in Central North Sea in a water depth of approximately 81m. It lies 41km from the UK/Norwegian median line and 188km from the Scottish coast. Being developed by Apache Corporation, the development will include a carbon steel tie-back to the Forties Alpha platform.
The field will supply fuel gas to the Forties field, which is located 23km away. The fuel gas will be used to offset the use of diesel for power generation on either of Forties Alpha, Forties Charlie or Forties Delta platforms.
Development drilling and subsea infrastructure installation on the Aviat field will begin in the third quarter of 2015 and the field is scheduled to come online in the second quarter of 2016.

Apache’s environmental statement for the Aviat field was approved in consultation with the Joint Nature Conservation Committee (JNCC), Marine Scotland (MS), the Maritime and Coastguard Agency (MCA), the Ministry of Defence (MoD) and the Northern Lighthouse Board.
Aviat gas field discovery, geology and reserves
Discovered in 2010 by the Aviat-1 well, the Aviat field lies in the Early Pleistocene Crenulate sands that are present within a mid-Miocene to mid-Pleistocene Eridanos Delta complex. The field consists of 99% methane gas.
With estimated recoverable reserves of 54.5 billion cubic feet (bcf) of gas, the field is anticipated to produce up to 2031.
