Hole Openers
Heavy-duty roller cones hole opener used for offshore 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.
Numerous designs exist, in sizes varying from a couple of inches to
above 50". Usages range from hydrocarbon drilling operations to
water drilling or horizontal drilling.
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.
