PRO-DRILL Environmental Drilling and Drilling Methods

PRO-DRILL undertakes extensive environmental drilling for our customers both in New Zealand and throughout the Pacific and Asia.

Due to the often sensitive nature of many of these investigations we respect client confidentiality and do not publish any details of these projects. References can be provided upon request.

PRO-DRILL Preferred Drilling Methods Include as part of Geotechnical and Environmental Drilling

At PRO-DRILL we use a number of different drilling methods that are determined by our experience and our customers’ requirements. These drilling methods are selected and used with New Zealand and the Pacific’s unique geological conditions in mind. During the drilling process a number methods may be required to meet the clients sampling and completion requirements. Customers leverage PRO-DRILLs experience to get the best result for every job.
PRO-DRILL Continuous and conventional wire line coring

PRO-DRILLs Preferred drilling method where an "undisturbed" sample is required for further testing and analyses. With this drilling method, SPT, Push tube and Formation permeability testing can be undertaken during the drilling process without the requirement to withdraw the drill rods from the well. Typical size core samples are:

    Excellent core samples are retrieved by using a selection of drilling bits and core catcher configurations to suit the geology and client requirements.

    PRO-DRILL Rotary wash drilling

    PRO-DRILLs Open hole drilling and sampling method using a fluid (water or oil based) flushing medium. With PRO-DRILL onboard mud pumps and PRO-DRILL auxiliary high volume pumps, Tri-cone roller type bits, Drag type bits and PDC bits we have the current capacity and equipment to rotary wash drill hole diameters in excess of 500mm for all your drilling requirements to a world class standard.

    PRO-DRILL Rotary air blast drilling

    PRO-DRILLs Open hole drilling and sampling method using air as the flushing medium. With our onboard compressors and PRO-DRILL auxiliary high pressure compressors, Tri-cone roller type bits, Drag type bits and PDC bits we have the current capacity dependant on ground conditions and the best equipment to provide this drilling method to a world class standard.

    PRO-DRILL Down hole hammer

    PRO-DRILL Open hole drilling and sampling method using an air driven down hole hammer and air as the flushing medium. With our onboard compressors and PRO-DRILL auxiliary high pressure compressors, DTH hammers and bit selection we have the capacity and equipment to drill from 4" to 12" holes

    PRO-DRILL Auger Drilling

    Augers can be used to provide a bulk disturbed samples for environmental purposes and when using hollow stem augers can be used as temporary casing whilst installing instrumentation. Augers are also used to "open hole" large diameters prior to setting conductor casing.

PRO-DRILL Vacuum Excavation and Service Locations

PRO-DRILL's fleet of up-to-date equipment includes a truck mounted excavation unit for passive drilling, vacuum excavation and service locations. Using water to dislodge soil, the vacuum system sucks the waste back to a holding tank on the truck for off site disposal. It is also particularly useful for keeping sites free of drilling fluids, specifically during directional drilling.
