LETTER: frackers will concentrate on flat areas

The guide to fracking assumes the shales strata is nice and horizontal, while every ex-miner knows they go up and down, folding and faults, inclines and anticlines.

If the surface topography is uneven, you can bet it’s the same down below.

This means the frackers will concentrate on flat areas for ease of operations, or use a bendy drill.
