  • Mineral prospecting case study 2

    We had recently carried out a copper prospecting survey. Electrodes were placed on the surface at 5m interval, one cable was connected to electrodes on surface and another cable is put in to the borehole. After repeating the surveys at nearby borehole, we generated two resistivity distribution images. We determined that the band of low resistivity approximately 30m below surface has a high chance ...

  • Landslide Investigation in Turkey - Case Study

    After a landslide, how do you know it’s safe to build again? In 2011, after a record-setting month of rainfall, a landslide devastated the infrastructure and roads near Cankiri in Northern Turkey, effectively cutting the highway from two cities. Fortunately, the landslide occurred in the evening, and there were no ...

  • Application of the AMT method case study

    Possibilities of the AMT method at searches of kimberlite pipes Last years a number of industrially important low magnetic kimberlite pipes have been discovered. That is why the role electromagnetic method increases at searching works in diamond bearing regions. The audiomagnetotelluric (AMT) sounding method has quite big depths of investigation. Tensor measurements increasing effectiveness ...

  • Application of radiomagnetiotelluric method case study

    Investigations of the landfill of industrial wastes by the RMT method The test site is the landfill of the coal ashes from power plants. The landfill was closed about 5 years ago. Material of the landfill is represented by powder-like particles and granules with the cross sizes from several millimeters up to the first centimeters. Wastes fill in a V-shaped valley of a stream (Fig. 1). The ...

  • MT & Gravity Survey in Delvina, Albania - Case Study

    MT & Gravity Survey In November 2012, SeismoTech s.ltd. was awarded a Gravity and Magnetotelluric survey in the Delvina Area (SW Albania), by Stream Oil & Gas Ltd. The scope of this project was to enrich with additional geophysical information the Delvina Gas field area, in order to conclude on optimum locations for well-drilling. The Delvina Gravity and ...

  • 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 ...

  • Locate buried monitoring wells case study

    A Phase II Environmental Site Investigation was being conducted at a gasoline station in Fort Myers, Florida. In order to minimize costs, our client intended to use several existing on-site monitoring wells rather than installing new wells. However, five of the existing wells had been covered with asphalt and were no longer visible. GeoView was tasked with performing a shallow geophysical study ...

  • Results of AMT survey at Patomsky crater case study

    The Patomsky crater is located in east part of the Irkutsk region (Russia). This geological object has anomaly appearance and is discordant placed relative to hosting geological structure. The crater has been discovered in 1949 during routine geological survey of the territory by geologist V.V. Kolpakov. The drastic investigations of Patomsky crater by modern technology have begun since 2006. The ...

  • Utility Locating and Mapping at a Power plant case study

    An expansion was planned at a power plant in west central Florida. As part of the design build plan, all of the utilities within the proposed building footprint had to be located and mapped. There were two phases of the investigation. Utility designation was the first phase. This involved studying existing as-builts, performing site walkthroughs with plant personnel in order to ascertain a ...

  • Scanning proposed borehole locations for Utilities case study

    Environmental and engineering firms often are tasked with performing soil borings for monitor well installation as part of a Phase II Environmental Site Assessment. This task becomes more challenging when the borings are to be installed in gasoline stations, right of ways or other areas where there are numerous underground utilities that are either unmarked or not properly located. GeoView can ...

  • Determining the design of Buried foundations case study

    Foundation Mapping Determining the three-dimensional design of foundations for telecommunications towers, buildings and road signs can be impractical and sometimes nearly impossible using conventional means. Properly applied geophysical test methods, hand probing and shallow test pits provide a very cost-effective and non-destructive approach to determining the design of foundations. ...

  • Locate abandoned production abandoned well case study

    Clearwater, Florida Historical records discovered during construction of a commerical building indicated that a deep well with steel casing was likely present within a portion of the project site. Regulatory officials halted construction and insisted that the presence (or absence) of the well be confirmed. If the well was present, it was required that the well be exposed so that it could ...
