Hi guys,

1.) I have to find averaging parameters of WOB, Torqe at bit, Flow rate, Mud weight and Mud Temperature for each interval.

for example

If I drill 4000'- 6500' , There are many numbers of above parameters every n second. So, how can I average it for calculation in these interval.

2.) How can i convert surface torque to torque at bit?

Thanks in advance man...
