Hydraulics Optimization - Hole Cleaning
To optimize hydraulics and achieve sufficent hole cleaning the following guidelines should be adhered to:
Pressure Losses Through System
P1= Frictional losses in surface lines
P2= Frictional losses in Drillpipe
P3= Frictional losses in Drill collars
PB= Pressure loss across bit
P4= Annular pressure loss across Drill collars
P5= Annular pressure loss across Drillpipe
