RE: Logging ES I doubt CGX would perform a DST (Drill Stem Test / Flow Test) - but if they were going to - it could take up to 5 days.
In the event of a discovery, CGX could run open hole wireline logs and possibly take some cores. This could take several days.
I tend to believe the longer CGX has the rig the better. Surely, CGX would not be screwing around with the Saratgoa at 500k/day.
