WA-360-P has an area of 1,213km2 (perhaps Petrobras meant to put 1.2Msqkm).
It has a water depth of ~200m comparable to Wheatstone but shallower than Pluto (500m).
Up until 1998 there was 760km 2D seismic data.
There was also 578 sq km 3D seismic data in 1996/7.
The latest 3D seismic completed by MEO is the 200 sq km 3D seismic in 2007 and 250 sq km in 2009.
Two wells have been drilled on the permit, Malus-1 (1972) and Eastbrook-1 (1998). Both were drilled on apparent geological time structure anomalies and were dry holes.
The recent Wheatstone and Pluto gas discoveries remained hidden until this decade. They were drilled on direct hydrocarbon indicator (DHI) anomalies, before the depth conversion nuances were fully understood. Artemis shares similar DHI attributes as these gas discoveries.
High amplitudes (often termed Direct Hydrocarbon Indicators or DHIs) are observed on both the existing and new data within the predicted reservoir section at Artemis. These high amplitudes exhibit a common depth termination which may represent a Gas Water Contact (GWC) indicating the possible presence of gas.
MEO has developed two depth conversion scenarios. The original depth conversion scenario placed the potential Artemis GWC at the same level as the Wheatstone GWC (-3,127m).
Presently, MEOs preferred depth conversion scenario places the potential Artemis GWC at -3,275m, which is deeper than the Wheatstone GWC.
