Technical Context
How hole openers work.
Use of Hole Openers
Borehole Enlargement
A hole opener is a fixed diameter bore hole enlargement tool that is utilized to expand the well bore beyond the original hole size drilled by the bit. HOC has many different types of hole openers to meet the various applications.
Function of Hole Openers
After the Pilot Bit
The hole opener is generally used after the pilot bit has drilled the original hole. A hole opener consists of a body with roller cones or it could be a fixed blade that would be dressed with PDC or crushed Carbide.
Key Features
Gauge Control & Cost Effective
A hole opener is a cost effective way to enlarge a pre-drilled pilot hole or to ensure that the gauge is maintained in a deviated hole. A hole opener with a bull nose below helps to mitigate any potential side track issues in wiper trip applications.
