Why Drilling Rate Is the Number That Blows Budgets
There is a difference between the clay and environments of the opertion. For example, a piling rig running 8 metres per hour in soft alluvial clay and the same rig in hard basalt might manage 0.8 metres per hour. If rig hit the hard rock then project cost doubles on the half.
Drilling Rate Reference by Formation
| Formation | Typical Rate (m/hour) | Cost Multiplier vs Soft Clay |
|---|---|---|
| Soft clay / loose sand | 8–15 | 1.0× (baseline) |
| Medium stiff clay / gravel | 4–8 | 1.5–2.0× |
| Weathered rock | 1.5–4 | 3–5× |
| Hard rock (basalt/granite) | 0.5–2 | 5–8× |
