The majority (~85%) of the Legendre is in 360p and only about 65% of the Calypso is in 360p, HOWEVER;
The technical presentation provided by MEO (37slides) available at: http://www.meoaustralia.com.au/icms_docs/59437_Artemis_Prospect_Overview.pdf
Clearly states that the mean recoverable reserves in East Artemis (360p) are 12.26 Tcf (+144 million barrels of condensate) on a number of slides specifically in the assumptions on slide 34 and the summary slide 37.
Now MEO have a 70% interest in Artemis. If we take MEO's interest into account, and then risk MEO's interest based on 32% GCOS, MEO's mean risked reserves in 360p are 2.75Tcf.
Given we have Blackwood and Heron also as existing discoveries I think MEO's technical team has proven itself and furthermore it is very rare for a company of MEO's size (sub $200m) to have reserves of this magnitude.
