Here's a brief summary of what they'v drilled so far at Winx-1 with WL logging underway as per the last ASX update.
Spud Winx-1 15th feb
1) Seebee target at 4252 feet
2) zone of interest: 4460 to 4530' : apprx thickness 70 ft
3) Nanushuk topset:
4667 to 4901': apprx thickness 234 ft (shows encountered on the Gas Chromatograph)
4) Top of Torok formation: 4913'
5) Sandstone sequence at :
6052' (shows encountered on the GC)
6) TD: 6800 ft on 3rd March. Logging underway
WL logs should confirm the exact net & gross thickness & fluid saturation within the zones of interest.
To get an idea of the WL Logs for the Nan-Tor sequence drilled in a discovery well, refer slide-20 showing the log from
Repsol's Q#3 discovery well.
This shows the Nanushuk on top of the Torok formation. Green line denotes the Gamma ray Log that is commonly used in the Industry to identify Sands vs Shales. The Nan Sands in this case r clear & highlighted in yellow. The sands in the Torok are Shale rich, so the sequence is thick with thin sandy zones that r waterwet. Red vertical line is from the Resistivity Log which helps to identify Oil & Water bearing zones. Log shows the oil payzone in 'green' which was subsequently tested by Repsol.
