RE:RE:Drilling I would generally expect CGX to have completed their open water work (running 36 conductor and 22 casing) given Aug 23 SPUD.
From this point on they will rig up their riser and proceed to drill towards total depth running various casing sections along the way. The Kawa well plan may comprise running various casing sizes until reach total depth. For example, 18-5/8, 16, 13-3/8, 11-3/4, 10-3/4, 9-5/8, and 7in - with various contingencies mentioned / planned for.
I would expect things will get interesting once they start drilling their 12-1/4" and 8-1/2" hole sections. Once they encounter primary and secondary intervals (3 zones of interest mentioned by CGX and Frontera) - they will likely "evaluate" these sections via a series of wireline logs (among a long list of reservoir evaluation methodologies). So, possibly three independent and separate evaluations will take place at different time frames.
In terms of timing, we are probably 60 days out before we get to the 12-1/4" hole section.
