36" Conductor Hole BHA

Guys,

I will be interested feedback/experience on

• 36" Bit W/ Stablizer BHA V/S 26" Bit w/ 36" Hole Opener BHA

Which will be more effective in terms of less vibration on BHA & good hole to run 36" Conductor Smoothly?

For Personal exp - on land Operation we have successfully used 36" Bit BHA without any issue with BHA but for Jackup Operations 36" BHA may cause string vibration problem in last two well so switching over to 26" Bit w/ 36" Hole opener BHA

Cheers, Mahesh
