Motivation Vista Clara NMR Geophysical Equipment helps clients image the subsurface to accurately define hydrogeologic properties including porosity, pore size, mobile and bound water content, permeability, and transmissivity. ...
During a recent training trip to Germany, Vista Clara provided extensive, on-site, training and equipment demonstrations to European customers to highlight magnetic resonance (NMR) technology, which enables them to directly detect and image subsurface hydrogeologic properties. The training conducted near Hanover, Germany, provided a comprehensive understanding ...
Aestus used our non-invasive ultra-high resolution subsurface scanning method to image the site and update the CSM Aestus integrated historical and targeted confirmation drilling data onto our GeoTrax Survey™ 2D subsurface images as well as our 3D visualization model.Drilling and sampling data were used to determine how ...
Ground-penetrating radar (GPR) is a well-established technology that has earned its place as the go-to technology for many subsurface imaging applications. No other geophysical method comes close to GPR's ease of deployment, nor the amount of ground that an operator can cover in a typical day. ...
Humidity in a material is a major cause for signal attenuation.Radargram The image produced by the signal from the receiver antenna is called a radargram. ...
This article showcases ‘passive’ seismic survey as a rapid and versatile alternative means of imaging the subsurface, using the Phase 2 extension area of Aggregate Industries UK Ltd’s Bardon Hill Quarry in Charnwood Forest, Leicestershire, as an example. ...
Process Our clients used SuperSting R1 for imaging to survey the subsurface of the site in 2D slices in terms of resistivity. ...
Identifying the subsurface profile for riverbank/bed filtration (RBF) using conventional methods such as drilled boreholes is usually labor intensive, costly and acquires only 1-D profiling. Hence, a 2-D ground resistivity method was used as an alternative to obtain a 2-D subsurface profile by extending to 200 m length at Kota Lama Kiri, Kuala Kangsar, Perak ...
This TD-PO model should be applied for detection and location of objects hidden in opaque media by subsurface TD radar system. The proposed approach allows considering of basic physical principles, governing electromagnetic radiation and scattering and reception, to form electromagnetic image of subsurface region by simulation of radar returns ...
ABSTRACT This paper deals with the application of ultra-wide band time-domain subsurface radars, equipped with special signal processing techniques, to realize non-invasive image testing of the building walls' internal structure that are made with brick, stone, concrete, reinforced concrete and other construction materials. ...
Abstract: The paper is devoted to design of impulse or equivalent ultra-wide baud array antenna for subsurface radar system. Receiving elements of this autenna are arranged in array with small physical aperture and polarimetric features. ...
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 ...
A multi-electrode resistivity survey, carried out over metasedimentary strata and metavolcanics in the Harare greenstone belt in northeastern Zimbabwe as part of a groundwater resources investigation, illustrates the ability of this technique to produce high-resolution images of the subsurface, which are useful for groundwater resources assessment. ...
Introduction The basic design principals implemented in the advanced UWB radar with time-domain operation and with the 100 - 900 MHz effective band are considered including real synthetic array and full-polarimetric schema. The radar is installing on a moveable platform for remote operation on the territories with radioactive pollution. This probing system should be employed near the nuclear ...
