  • Onshore logistics preparations underway to support drilling campaign
  • Sasanof is a 2U Propsective Resource of 7.2 Tcf gas and 176 Million bbls condensate (P501) with 32% geological chance of success

The MS-1 is expected to take approximately four days to reach the Sasanof Prospect, which is approximately 200 km northwest of Onslow, Western Australia, following which the rig and support vessels will commence the laying of the anchor spread prior to the commencement of drilling the Sasanof-1 exploration well.

ERCE estimates the Sasanof Prospect to contain a 2U Prospective Resource of 7.2 Tcf gas and 176 Million bbls condensate (P501), with a high case 3U Prospective Resource estimate of 17.8 Tcf gas and 449 Million bbls condensate (P101).

Sasanof is a large, seismic amplitude supported, structural-stratigraphic trap in the high-quality reservoir sands at the top of the Cretaceous top Lower Barrow Group formation on the Barrow Delta within the Exmouth Plateau.

Sasanof-1 will be Western Gas' first well drilled from its extensive exploration portfolio surrounding the existing Equus Gas Project that contains a discovered resource of 2 Tcf and 42 MMbbl (2C Gaffney Cline2).
