How to choose a model
| IADC | Rock formation | WOB (KN/mm) | PRM(r/min) |
| 116/117 | Low compressive strength, high drill-ability and extremely soft formation, like soft shale, clay,etc. | 0.35~0.90 | 180~80 |
| 126/127 | Low compressive strength, high drill-ability and soft formation, like shale, clay, soft limestone, salt rock, etc. | 0.35~1.00 | 180~80 |
| 136/137 | Soft to medium soft with low compressive strength or soft with hard interlayer, like anhydrite, soft limestone,sandstone, etc. | 0.37~1.05 | 130~60 |
| 216/217 | Medium hard formation with relatively high compressive strength and hard interlayer, like hard shale, sandstone, limestone, etc. | 0.5~1.20 | 100~50 |
