Horizontal Wells

13 October 2017

What is the benefit to drill a Build Up Section from KOP to Landing point at 89° with 8-3/8in instead of 8-1/2in.
8-1/2in and 8-3/8in Bits have more or less the same Diameter but some companies prefer to run with 8-3/8in instead of 8-1/2in why ?

But for vertical wells they run 8-1/2inCan any one clarifies?

Thanks
