The Cost of a Borehole Borehole Drilling EDRS

The cost of a borehole is largely dependent on its depth and the amount of casing to be used. The type of rock that we have to rill through also influences the price, as does the actual ground conditions. While most people expect the easiest drilling to be into soft and loose geologies, the opposite is generally true. A great difficulty of the
