Oz,

"...we could expect to be entering the first target Wednesday or Thursday?"

No, that would be too early by my rough calcs...rough because a bit hard to work out the drilling rate progress as no info for depth and time to set the conductor, and no time given for reaching the 13-3/8" casing point last Friday. I made a guess.

Anyway, a rough calc going on the info supplied so far would be a rate of 216m/day, or roughly 9m/hr. This is highly variable depending what you're drilling through.

So I expect to be at the 9-5/8" casing point sometime on Thursday morning. They would then need to run and cement the 9-5/8" string...probably 2 days minimum. Maybe get an ann Fri...imo.

After the cement's gone off (8hrs min), we can then drill out the 9-5/8" plug and drill ahead the 8-1/2" hole section for the last 687m to TD.
It's during this section that we should be picking up any elevated readings I referred to previously...if we have something.

Bear in mind this is pretty rough without specifics to work from.
