120m or up to 474m of gas in zola-1

From the 16th of March drilling report:

"The well has now encountered gas saturated sands in the interval from 4,197m to 4,671m, with over 120m (true vertical thickness) of potential gas saturated, reservoir quality sandstone likely present"

474m is the area of interest that contains 120m of gas, but it could be more?

From the 22nd of march (Today) presentation:

"Sidetrack being drilled to run wireline logs
over full hydrocarbon column"

Meaning that they could have run wirelogs over some of the 474m but are or have drilled a sidetrack over the part where the drill line is jammed to wirelog the full column.

Looking forward to the weekly drilling report Tomorrow afternoon to give clarity.

imo The news has been good so far, should not jump at shadows now.
