2.   SlimholeFull-Wave Triple Sonic Probe FWS60

The Slimhole Full-Wave Triple Sonic FWS60sonde is a compact tool that can be operated and by a single operator andintended for geotechnical and mining applications. Its rigid constructionprovides an effective centering inside the hole.

The piezoelectric transmitter is stimulatedby a high voltage pulse and radiates high frequency acoustic waves through theborehole fluid and formation up to each receiver.

The sonde records the ful-wave train fromthree receivers simultaneously and these waveform data may be exported tointerpretation software such as WellCad for calculation of compressional, shearand Stoneley velocities.

The Slimhole Full-Wave Triple Sonic FWS60sonde main applications are:

●  Geotechnical /Mining/Water

●  Fracture and permeabilityindication in hard rock

●  Rock strength and elasticity

●  Lithology identification

●  Porosity

●  Correction of seismicvelocity

3.  Natural GammaSpectroscopy Sonde GRS42

The Natural Gamma Spectroscopy GRS42 sondeanalyses the energy spectrum of the gamma radiations from naturally presentisotopes in the formation surrounding a borehole. This tool is offered withseveral scintillator options depending on the field application.The NaturalGamma Spectroscopy GRS 42 sonde uses a one inch diameter crystal and isrecommended for highly radioactive environments.

The Natural Gamma Spectroscopy GRS42 sondeis recommended for the following applications:

●  Mineral Detection

●  Lithology Characterization

●  Sedimentology

●  Contamination Studies

4.  Focused ElectricSonde GUIP38

The Focused Electric GUIP38 sonde measuresresistivity with an excellentvertical resolution and depth of investigation.

The sonde includes a central current-sourceelectrode placed between twoguard electrodes, maintained at the samepotential.Current from the central electrode is constrained to a thin disk bythe presence of the two guard electrodes and returns to the cable armor above a10-meter insulated section. The central electrode potential with respect to asurface voltage reference and the measured current are combined by the sondeprocessor to calculate the apparent formation resistivity.

The FocusedElectric GUIP38 sonde main features are:

●  Indication of permeablezones and porosity

●  Indication of fractures andpermeable zones

●  Bed boundary and thicknessmeasurements

5.  MagneticSusceptibility Probe MS42

The Magnetic-Susceptibility MS42 sonde is anew development of the industry-standard Bartington Instrument BSS02 product.

It’s a low-frequencydevice specifically designed for mining applications showing outstandingstability against pressure and temperature variations.

This sonde relies on a similar principle tothe induction sonde where a current is induced by an oscillating magnetic fieldin the sonde within a toroidal zone offormation at some radial distance from the sonde coils. The oscillating currentproduces a secondary field which is detected by the receiver coils. The “in-phase” signal is a measurement of thesusceptibility of formations having magnetic properties.

The Magnetic-Susceptibility MS42 sonde mainfeatures are:

●  Formation conductivitymeasurement in dry or fluid-filled borehole or even in PVC casing

●  Ideal for use in smalldiameter boreholes

●  Excellent thermal andpressure stability across specified operating range

●  Natural gamma measurementavailable for correlation

6.  Optical BoreholeTeleviewer OBI52

The Optical Borehole Televiewer OBI52 fromelectromind represents a major technological advance in the field  of borehole imaging sondes. The resultsobtained with this sonde surpass anything previously possible in terms  of image resolution, color rendering andlogging speed. The  Optical  Borehole Televiewer  OBI52 provides a continuous high resolution 360 degree  oriented  image of  the  borehole wall.  

Its  applications include:   

●  Fracture and StratigraphyImaging and Characterization   

●  Replacement of Coring   

●  Lithological Characterization   

●  Replacement of BoreholeTelevision Survey   

●  Casing Investigations
