  • Assessment of geo-hazard potential and site investigations using Resistivity Imaging

    The use of geophysical methods for evaluating subsurface contamination of sites is becoming increasingly popular all over the world. The paper presents the assessment of geo-hazard potential of a site in the City of Duncanville, Texas using Resistivity Imaging (RI). Resistivity Imaging was being used to identify areas of environmental concern and to develop a detailed image of subsurface ...

  • Time-lapse resistivity investigations for imaging saltwater transport in glaciofluvial deposits

    Abstract  Five intersecting resistivity sections have been measured in glaciofluvial deposits hosting an aquifer of regional importance situated along a heavy traffic highway in Sweden. The winter salt spreading has caused a regular salinity increase through the years. For imaging the transport of saltwater in the aquifer, the sections were measured exactly in the same location before and ...

  • Resistivity system voltage output

    One limit of FlashRES resistivity meter is its voltage output. It can output maximum voltage of 350v, this is because the multi-core cable of the FlashRES cannot withstand voltage over 350v. the multi-core cable contains 32 small wires, voltage higher than 350v will damage these wires and make the cable short circuit. We thus limit the maximum voltage output for safety reasons. Reference ...

  • Roll along resistivity survey

    A roll-along survey is a method for operator to survey a long line. After the initial survey, the operator will leave one cable on the ground and move the instrument and cables forward. So there is always one cable overlap between two surveys. Alternatively, the operator can divide the cable in half and only overlap 16 electrode spacing. In this way, the opearator could complete the survey ...

  • The key advantages of FlashRES resistivity meter

    FlashRES-UNIVERSAL is the first instrument in the world that can fully utilise all its electrodes during data collection.  It is a significant technological breakthrough. FlashRES-UNIVERSAL has following key advantages: FlashRES is a 61-channal resistivity/IP system and it is extremely fast For each current injection, conventional resistivity systems usually collect ...

  • Compare popular resistivity meters with FlashRES

    Although most resistivity meters nowadays can collect resistivity, IP and SP data and most of these systems are multi-channal resistivity meters, there is still a technical gap between traditional and next generation resistivity meters. FlashRES has six to 8 times more channel than traditional system, this means larger data quantity, which could help the resistivity inversion image ...

  • The suitable battery for FlashRES resistivity meter

    Air freight battery pack is extremely diffculty in Australia, this makes installing internal battery to FlashRES resistivity meter counter-productive for ZZ. We thus use an external battery and connect it with our system. The correct external battery for our system should be a 12 volt truck/car battery of ≥ 90 Amp/hr is needed. Reference ...

  • What is 61-channel resistivity meter?

    FlashRES resistivity meter has 64 electrodes, it uses one common ground electrode, two electrodes as current injection electrodes. For each current injection between A and B, the FlashRES resistivity meter measures the potential on remaining electrodes against the common ground electrode. In this way, 61 MN voltages are measured and hence FlashRES is a 61 channal resistivity meter. ...

  • The exploration depth of FlashRES resistivity meter

    The formula for calculating the maximum depth is universal for all resistivity meters. The exploration depth depends on the survey line length. the survey depth is usually 20-25% of the survey line total length. For example, for 10m takeout cables, the total length of the cable is 10m*63=630m and this means the exploration depth is 0.2*630m to 0.25*630m. The resolution is 10% of ...

  • Surface resistivity survey case study 1

    The purpose of this surface electrical resistivity survey was to delineate the event direction of a gold ore deposit. The surface electrical resistivity survey uses a 10m interval cable, that permits the FlashRES 61 channel resistivity meter to detect depth up to 120m. The depth is dependent on the cable length.  The system found an occasional resistive band from 0-350m. This knowledge was ...

  • Crosshole resistivity survey case study 2

    Crosshole resistivity survey to search out industrial waste water This exploration survey used the crosshole resistivity technique to observe whether or not an industrial waste water plant is leaking. Chemical analyses found that this specific waste water has a low resistivity compare to normal groundwater. Our recent example shows at depth of 45m a comparatively high resistive zone fabricated ...

  • Surface borehole resistivity survey case study 1

    Surface borehole method can be used to effectively maximise the value of existing boreholes. This is because surface-boreholre method can give operator more geological and geophysical information around the borehole. For example, we did a surface-borehole survey, where there was already well-known mineralisation existing between 60-80m in Figure one and 100-115m. The inversion resistivity ...

    Surface-points electrical resistivity surveys area can be used to detect one or several known underground anomalies in timely manner. A minimum of one borehole is needed to carry out Surface-points electrical resistivity surveys. A FlashRES electrical resistivity meter allows users to position active electrodes anywhere they want in the borehole, by conducting the survey in a surface-borehole ...
