Hi guys,
We have plan to opening the hole while drilling :
1. 12-1/4" X 14-3/4" Concentric Underreamer in Build up section till
37 deg inclination
2. 9-7/8" X Fixed Blade HO 10-5/8" X Concentric Under Reamer 12-1/4"
in tangent section.
Could share all information or experience :
1. Experience recommended of Percentage of flow rate by pass through
underreamer in both section specially for 9-7/8" bit X fixed HO 10-
5/8" X 12-1/4" Concentric underreamer?
2. BHA configuration with regard stabilization issue.
3. Recommend cutter size of fixed hole opener and concentric
underreamer to minimize vibration impact and premature wear.
Appreciate with your information
