Borrox AP® Roller Reamers

The Borrox AP* advanced performance sealed-bearing reamer has the flexibility and durability to meet rigorous downhole demands. Hole gauge maintenance and torque reduction characteristics can be customized with the Borrox AP reamer. To help operators take on different formation applications, the Borrox AP reamer works with three different cutter assemblies: KSX* high-strength TCI reamer cutters for soft to medium-hard formations; RSX* milled-profile torque- reduction reamer rollers for torque reduction applications, and DEX* diamond-enhanced insert reamer cutters for high abrasion and impact resistance, a hard formation profile. Cutter assemblies can be changed easily on the rig floor to accommodate a range of wellbore conditions. Application: • low packed hole assemblies • medium to severely packed hole assemblies • extremely abrasive drilling conditions Benefits: • available in all common hole sizes • reduce downhole torque caused by wellbore spiraling and doglegs • maintains borehole quality • maintains hole gauge in extreme conditions Features: • blank ended manufacturing means the tool can be configured for near bit and string placement in the BHA • high-flow body increases annular total flow area (TFA) to improve hole cleaning • longer full-gauge cutting section enhances gauge maintenance • proprietary seal endures high loads, temperatures, and rotary speeds to extend bearing life • three cutter assemblies allow customization for different applications • cutter assemblies changed safely and easily on rig floor • optional real-time data connection for use with Schlumberger LWD tools
