Just say the Colypso sands are 200m thick and meo are out to map this hole good and proper this time as they know they will be drilling these formations agian and agian.
I dont think they did this on the Zeus hole.
so when they put the core bit on for core samples the length of those samples depend on how many core tubes put on the string behind the core bit.
so fifty metre core samples means they have to pull string 5 times, 3kms each pull will take time.
