Typical Application of Hole Openers

A hole opener is then tripped into the well bore to the beginning depth and then utilized to enlarge the pre-drilled pilot hole. This is the most typical, however, hole openers may be also utilized to ensure that the gauge of the pilot hole is intact, this method is generally known as a wiper trip. Wiper trips are best for deviated holes where trying to run the bit back to the end of the section could actually case a side track scenario in softer formations. Hole openers may also be utilized in the same drill string as the bit to perform a function of actually enlarging the well bore or ensuring that the bit gauge is maintained and clean up any formation beds that may accumulate throughout the section being drilled.

 

Key Features of Hole Openers

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.
