Why use stabilizer?
-Control hole deviation,while minimizing crooked holes
-Pack the formation
-Control vibration,increasing bit&drill pipe life
-Pack wall of hole to prevent caving,minimizing particles in the hole bottom,reducing re-drill time
-Help back drill steel out of collasped holes
-Increase penetration rates&reduces repairs to rotary head gear box,resulting in greater drill availability
