Rotary seal for directional drilling tools
Publication/Patent Number: EP1247787B1 Publication Date: 2012-10-17 Application Number: 02251373.3 Filing Date: 2002-02-27 Inventor: Hughes, Peter Raymond   Griffin, Nigel Dennis   Colebrook, Mark   Assignee: Camco International (UK) Limited   IPC: B22F7/06 Abstract: The method involves determining a layout of cutter locations in which cutters (20) are positioned upon a bit body (10), and determining wear rate of cutters in cutter locations. Low and high abrasion resistance cutters (20a,20b) are selectively mounted in each cutter location based on determined wear rates. The low abrasion resistance cutters have same impact toughness as the high abrasion resistance cutters.

Polycrystaline diamond with a surface depleted of catalyzing material
Publication/Patent Number: EP2145870B1 Publication Date: 2011-09-07 Application Number: 09012013.0 Filing Date: 2001-06-25 Inventor: Griffin, Nigel Dennis   Hughes, Peter Raymond   Assignee: Camco International (UK) Limited   IPC: C04B35/52 Abstract: The present invention provides a superhard polycrystalline diamond or diamond-like element with greatly improved resistance to thermal degradation without loss of impact strength. Collectively called PCD elements, these elements are formed with a binder-catalyzing material in a high-temperature, high-pressure process. The PCD element has a plurality of partially bonded diamond or diamond-like crystals forming at least one continuous diamond matrix, and the interstices among the diamond crystals forming at least one continuous interstitial matrix containing a catalyzing material. The element has a working surface and a body, where a portion of the interstitial matrix in the body adjacent to the working surface is substantially free of the catalyzing material, and the remaining interstitial matrix contains the catalyzing material. This translates to higher wear resistance in cutting applications, higher heat transfer capacity in heat sink applications, and has advantages in numerous other applications including hollow dies, indentors, tool mandrels, and wear elements.
