Economics.

There are many ways of applying cost effectiveness rules to the purchase of drilling equipment  each purchaser will have different criteria to arrive at the correct package to purchase.

• By restricting the construction equipment package weight to a minimum can result in the most effective per bore hole in both performance time and drilling cost.   Like the horse mounted cavalry soldiers of old – light, mobile and fast.   Purchasing an equipment set too heavy adds to costs throughout it operation from mobilisation to storage

• All PAT equipment is designed and built for an arduous life on site – and would generally be expected to work its first 12 -24months without a huge maintenance cost.   The simple basis of choice is the drilling depth and diameter to be drilled – the larger the machine the greater weight of drill pipe it can carry in a hole and the deeper it can drill – the larger the machine the more powerful the rotation and the total mass  so it is easier to put weight on the drill pipe.

• When drilling rock – the dominant requirement is compressed air – the more air that is available in both volume and pressure the faster the drilling will be resulting in the lowest cost per metre – provided production can be constant – ie numerous holes lined up to be drilled one after the other.

PAT generally can match a machine to a clients needs given the borehole construction geology and details of terrain to be crossed – and would respond to a simple E mail request with a complete package of drilling equipment with itemized prices to allow client opportunity for final choice and costing.
