Ann: West Erregulla Update, page-31

Depends on what they see on the seismics, WL logs & core data. WE4 is 1.5 kms ESE from WE-2. So the main thing for STX is to establish connectivity/ continuity of the sands betwn the 2 wells.

WE-5 location is apprx 1.6 kms to the North of WE-2, so it will also provide useful info for the company to update the subsurface modelling.

LWD data will help in establishing the 'top' of the Kingia, which we were told last week is at 4870m. They've drilled 16m & then cored 45 metres to 4931m. So that's 61m so far. I wonder if there is still some a little bit of Kingia sands left to drill out. I guess all will b revealed in the next progress update.

Flowtest at WE-2 was over 48m section from 4799-4961m. Current depth at WE-4 is 4931m, I think we'll just wait for the drill bit to spin & reveal the thickness of the Sands on the gamma ray log.

Drillrate (i.e, ROP) should slow down when they hit the top of the B/B Shale & the Gamma Ray will pick up the Shale line shift straightaway to give us Kingia's Gross Thickness intersected, i.e, from 4870 to 49xx metres. Hope this helps.
