PDC Hole Opener for Wells Drilling
A hole opener is a device used to enlarge the borehole during a well drilling operation.
It can be positioned either above the drill bit or above a pilot run inside the existing borehole. Usages range
from hydrocarbon drilling operations to water drilling or
horizontal drilling.
Hole openers are also used when a hole must be logged, since logging tools generally cannot handle holes larger than 17
and a half inches in diameter.
Hole opener arms have to sustain heavy loads during operations and are generally made of high-grade alloy steel, welded onto a
solid alloy steel body.
Some designs feature replaceable arms, allowing for size changes
but decreasing overall robustness. Numerous designs exist, in sizes
varying from a couple of inches to above 50".
They can have rolling cutters or drag blades, and can be used for
either direct or reverse circulation applications.
