Formations In Which Diamond Products

ARE ECONOMICAL

  • Polycristalline Diamond Compact (PDC) Bits
  • Very weak, poorly consolidated, brittle, shallow sediments (e.g. sands, silts, clays — Miocene)
  • Low strength, poorly compacted, brittle, non-abrasive, relatively shallow sediments, precipitates and evaporites (e.g. salt, anhydrates, marls, chalk — Devonian/Muschel chalk)
  • Moderately strong, somewhat abrasive and ductile, indurated medium-depth sediments, precipitates and evaporites (e.g. silty claystone, siliceous shales, porous carbonates, anhydrites — Eocene)
  • Natural/Thermally Stable Diamond Bits
  • Moderately strong, somewhat abrasive and ductile, indurated medium-depth sediments, precipitates and evaporites (e.g. siliceous shales, porous carbonates, anhydrite, silty claystone — deep Miocenes)
  • Strong and abrasive indurated, very ductile deep sediments, precipitates and evaporites (e.g. sandy shales, calcareous sandstones, dolomites, limestone — Pennsylvanian/Mississippian)
  • Very strong and abrasive, indurated ductile and non-ductile (e.g. Bunter sandstone, bromides, etc.)
