Bore hole services and Bore Geophysics

Borehole Geophysics

Borehole geophysics has proven to be an indispensable tool for our clients in coal exploration, mineral mining, coal seam gas exploration and scientific research to name just a few. It is an incredible value-adding tool to confirm target depths, characterise overburden, assess dipping angles and much, much more.

Site investigation planning

Groundsearch uses state of the art combination tools from Century Geophysical Corporation to maximise the information gathered from the hole, while maintaining usability and the convenience to transport the equipment to operate from nearly anywhere (and over the years our clients have occasionally pushed this “anywhere” claim to extremes! – See “Our Projects”) Our most popular tools are listed here, but we can get in a tool to suit almost any endeavour very quickly.

With the backing of a huge amount of experience in exploration projects all over NZ, and a comprehensive support structure, we can manage your borehole geophysics effectively and efficiently. Email us for more information.

Borehole Tools

9239 Dual Density Sonde – Coal Combination Tool

The Series 9239, Compensated Density logging tool uses the two focused density detectors to compute borehole compensated density real time while logging. No post processing required to produce CDL bulk density. Additionally, the tool also records natural gamma, caliper , medium guard resistivity, and borehole temperature.

The 9239 is a very well proven, diverse and reliable tool which is ideally suited for coal exploration as well as a variety of other applications. It delineates coal seams with fantastic accuracy, and can operate inside or outside the water column, and even inside or outside drill rods or casing.

Acoustic Scanner

The Acoustic Televiewer takes an oriented “picture” of the borehole using high-resolution sound waves. This acoustic picture is displayed in both amplitude and travel time. This information is used to detect bedding planes, fractures, and other hole anomalies without the need to have clear fluid filling the boreholes.

The televiewer digitizes 256 measurements around the borehole at each high-resolution sample interval (.005 meters/.02 feet). This data is oriented to North and displayed real-time while logging using the Visual Compu-Log software. Analysis includes color adjustment, fracture dip and strike determination, and classification of anomaly. It allows information to be displayed on the graphical screen, plot, and in report format. Optionally, the tool can be equipped with a natural gamma sensor.

Full Wave Sonic

The Full Wave Sonic tool contains a single transmitter and dual receiver to record formation travel times. The full wave form data is also recorded simultaneously, along with near and far travel times, borehole-compensated delta time, calculated sonic porosity, receiver gains, near/far amplitudes and natural gamma. The sonic or acoustic log uses the basic principle of sound waves traveling through a media. The Century sonic system uses a single transmitter and dual receiver system for recording the travel times of the formation. The receivers are spaced approximately 2 and 3 feet, from the transmitter. Therefore, a 0.3 m (1 ft.) calculation can be made to measure this interval transit time.

9410 Dipmeter

The Dipmeter tool is a formation strike and dip directional probe primarily used in mining and environmental logging applications. Additionally, the tool also records natural gamma, X-Y calipers, and borehole deviation is computed from the slant angle and bearing measurements calculated from the inclinometer and magnetometer sensors. To ensure accurate strike and dip measurements in small-diameter holes, special care should be taken when calibrating the calipers to maximize their accuracy.The image to the right shows a set of dipmeter data with “tadpoles” giving dip and dip direction of the bedding structures. The bed boundary is picked from the current logs. The boundary is then cross-correlated between each pad data and merged to give the dip of the best “plane ” through this data.

Ground radar

Ground Radar

What is Ground Radar?

Ground penetrating radar (GPR) is a high-resolution, shallow penetrating geophysical technique.

It gives images of the underground.

Voids, cable, pipes, treasure, geotechnical targets, and geology.

Range ~1m up to 30m or more.

Site investigation planning

Figure 1, Field surveys

Site investigation services

GPR gives accurate images of the shallow subsurface.

Applications include Non Destructive Tests (NDT’s) in construction and roading, utility location, and void detection.

It is versatile and cost effective, and Groundsearch has an impressive track record of successful surveys using GPR.

MASW or Soil Stiffness

MASW and Mapping of Shear Wave Velocity

What is MASW?

Multichannel Analysis of seismic waves

Shear Wave velocity ( Vs) an elastic constant -- Young’s modulus

Vs -- ground strength (stiffness) and load-bearing capacity.

  • Rock head Depth

  • Soil Stiffness

  • Void Location

Map soil strength without drilling.

Seismic Equipment in action

Measure the Shear wave velocity of the soils using a geophysical survey and very smart processing.

A very powerful and fast geophysical method.

Active mode – to 25m

Passive Mode up 100m range .     No need for sources uses natural ground noise source

VALUE ADDING SOLUTIONS FOR INVESTIGATIONS

  • Rock Base and Geotechinical data from MASW

  • Mapping Rock head to 100m or more

  • Determine soil stiffness and strength directly from Geophysical Data

  • Liquefaction Potential

  • Correlate with CPT/ SPT /Drill Hole and other site information
