Often a typical mobilisation will cover a ‘black top’ journey on reasonable public roads that are well used by cars & trucks – but then the final few kms onto a pegged site  might be ‘off road’.

A fully cost & time efficient drilling operation aims to transports equipment to a site in the minimum time and road miles traveled.  By equipment & material choice keeping the total weight of the ‘mobilisation’ to a minimum helps achieve the optimum.

PAT default option is  to supply equipment on rugged off road trailers – so  the investment made in expensive vehicles make those vehicles fully available and adaptable for all the transport requirements of a drilling operation.

Observations  made over the years – a light, powerful 4WD pick-up may be able to access sites but can total up a lot of time and distance traveled making multiple trips to move equipment to a single site.  In comparison a heavier truck can fail to make a vital river or stream crossing due to being too heavy for the existing structures. Fast ‘black top’  vehicles can bog completely and cause long time delay whilst a slower more capable off road vehicle on the black top will be the more efficient.

PAT do not generally supply vehicles – only if especially requested.

Borehole completion.

Mud Drilled holes need careful development after well screen is placed – the most convenient method is compressed air – but a small volume development compressor will achieve this job – without having to deploy a machine with capacity to air drill on its own.

Once a hole is completed it is good practice to undertake a nominal test pump in part  to clean the water to drinking quality and part to determine the possible flow rate and pumping level for a permanent pump installation.  PAT make integrate sets of equipment to do this work.
