Program plan for the development of advanced synthetic-diamond drill bits for hard-rock drilling

Glowka, D.A.; Schafer, D.M.

Eight companys have teamed with Sandia Labs to work on five projects as part of a cooperative effort to advance the state of the ar in synthetic-diamond drill bit design and manufacture. DBS (a Baroid Company), Dennis Tool Company, Hughes Christensen Company, Maurer Engineering, Megadiamond, Security Diamond Products, Slimdril International, and Smith International. Objective of each project is to develop advanced bit technology that results in new commercial products with longer bit life and higher penetration rates in hard formations. Each project explores a different approach to synthetic-diamond cutter and bit design and, consequently, uses different approaches to developing the technology. Each of these approaches builds or the respective companies` capabilities and current product interests. Sandia`s role is to assure integration of the individual projects into a coherent program and tc provide unique testing and analytical capabilities where needed. One additional company, Amoco Production Research, will provide synthetic-diamond drill bit research expertise and field testing services for each project in the program.
