Hydraulics Optimization – Hole Cleaning

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
