Anchorage, Alaska Patent of the Year – 2024/2025
Alaskan Energy Resources Inc. has been awarded the 2024/2025 Patent of the Year for its innovative protection clamp for downhole drilling. Their invention, detailed in U.S. Patent No. 11993986, titled ‘System, method and apparatus for a protection clamp for pipe’, utilizes a hinged metal sleeve embedded with ultra-hard inserts to shield drill pipe connections from wear and damage.
This clamp is designed to encase the exterior of drill strings without adding length, ensuring seamless integration into existing systems. Its exterior features recesses housing polycrystalline diamond compacts (PDCs), tungsten carbide, or impregnated diamond inserts. These materials provide a low-friction surface that resists abrasion and rotational stress. The sleeve bodies, made of metal or ceramic, are mechanically locked together, ensuring a secure fit that prevents axial or rotational movement during operation.
The innovation addresses a critical challenge in drilling operations: protecting pipe joints from the harsh conditions of downhole environments. By enhancing durability and reducing maintenance needs, this clamp can lead to significant cost savings and increased operational efficiency.
Invented by Lee Morgan Smith and assigned to Alaskan Energy Resources, Inc., the clamp exemplifies the company’s commitment to advancing drilling technology. With this patent, they continue to solidify their position as a leader in the development of robust solutions for the energy sector.
