Productivity varies with parking, access between boreholes, ground conditions, well installation, waste handling, water supply and cleanup requirements.
| Ground / Method | Good access Good access + onsite parking Good site access with parking available onsite. | Tricky access Tricky access + tricky parking Tricky site access and tricky parking onsite. |
|---|---|---|
| Decent sandstone | up to 20 m for one borehole | up to 15 m for one borehole |
| Decent shale | up to 15 m for one borehole | up to 12 m for one borehole |
On top of the drilling estimates above, allow extra time for: 2 hours per borehole at the depths above where the rock is highly fractured
Review access, required drilling method, target depth, parking, water availability and borehole movement before mobilisation.
