| titleOfInvention | Drill but seal including nanomaterial |
| abstract | A bit for drilling subterranean formations that includes a bit body 10; a bearing surface; a cutting structure mounted on the bit body. Also present is a bearing surface, and an annular seal 33 for retaining a grease between the bearing surfaces The annular seal 33 includes a flexible and resilient seal body formed from an elastomer composition, wherein the elastomer composition comprises an elastomer material, a curing agent, and 10% or less by volume of a nanomaterial additive selected from one of nanotubes and clustered nanodiamonds. Various compositions for the elastomer are claimed and the nanomaterial additive may be a functionalized nanotube. |
