Dear Forum members,
We are drilling ahead 8.5” hole with RSS BHA building angle to 12.9 and then dropping angle to 5.0 and turning to the right (from 248 to 25)
After POOH we plan to make a wiper trip with a different BHA before running 7” casing.
There are two opinions in the team. One is to run a BHA that mimics the previous drilling RSS BHA.
Second is to run a stiff BHA with 3 undergauge stabilizers to ensure the hole is wiped well to accept the 7” casing and avoid casing stuck.
What is your opinion? How high are the risks of running stiff BHA with 3 undergauge stabilizers? Should we not just run similar configuration BHA as the drilling BHA as a general rule of thumb?
I have the same thoughts as Elman, wellpath looks benign from the details provided. Follow the basics, determine the condition of the hole in realtime during drilling and POOH, then make a judgement on facts. Good luck !
