Chalk Drilling Performance

24 November 2006 Hello Everybody,

Thanks for the great response for the BHI VertiTrak.

I know some of us probably are having a hard time in drilling the
Chalk in the central North Sea. For the best practice purpose, could
you please share some experience of what bit YOU ARE PROUND OF MOST
in your area with your BHA(powerdrive, Autotrack, PDM, etc)? I think
each bit company has very good bits. No Detail required, only to see
if there is a common in blades numbers, cutters numbers, cutter
sizes, etc?

Thank you again for sharing,

Jie
