Vertical Electrical Sounding (VES) is by far the most used method for geoelectric surveying, because it is one of the cheapest geophysical method and it gives very good results in many area of interest. This method uses two current electrodes situated at the end points with the two measuring electrodes continuously spreading in the line. This yields depth-wise resistivity variations, which are interpreted in terms of aquifer aquitards at depth and salinity of water in the aquifers. The field measurements technique is adjustable for the different topographic conditions and the interpretation of the data can be done with specialized software, with a primary interpretation immediately after the measurements. The results of VES measurements can be interpreted qualitatively as well as quantitatively. The technology is applicable on rivers and lakes also, making it possible to find out the geology of underwater terrain. This method has proven efficient in designing vertical guided boreholes and other engineer projects.[Click here for more info]

Water managers and ranchers in Western Montana can use NMR measurements to inform regional groundwater flow models and to select appropriate irrigation practices. Measured decay times, which are used to estimate subsurface hydrogeologic properties, are sometimes influenced by the presence of magnetic minerals. At this field site, T2* decay times from FID measurements were found to be very short (~15-50 ms), initially suggesting that groundwater was bound in low permeability silts. Supplemental spin echo measurements, however, revealed that the T2 decay times were actually much longer (~100-400 ms). While FID measurements were strongly affected by the magnetic geology, robust spin echo measurements accurately reflected the high permeability of the shallow sand and gravel aquifer. This study demonstrates that the characterization of aquifers in magnetic geology requires the ability to measure very short signals and high-quality spin echo decays.[Click here for more info]

Our involvement with Geophysical & Seismological Instruments starts at the early 2000’s as instrument designers and field support for micro-seismic monitoring companies. We have designed and manufactured several types of seismic monitoring instruments, focusing in low cost, easy of use, very low power consumption and high reliability. Our instruments have been used in hundreds at projects in the most difficult conditions and harsh environments, worldwide, We are more than happy that they never had any operational problem or fail. More than 2.650 instruments have been deployed worldwide up to now.

Our company bears all the accumulated experience of the past years, broadens its activities into new seismic monitoring applications and launches commercial co operations as well as new products in the geophysical / seismological sector.

Our target is to supply the industry with portable, low power, low cost, geophysical and seismological instruments, such as 32bit ADC seismic digitizers & recorders, wide-band seismic sensors and processing software for exploration geophysics and seismology. Our instruments are ideal for local and regional seismicity and micro-seismicity monitoring and for seismic events such as those induced by unconventional hydrocarbon extraction (e.g. hydraulic fracturing).

Our high fidelity digitisers/recorders ensure that these signals are recorded with the highest resolution and accurate timing. They can be networked over seedlink telemetry providing real time monitoring networks.

We have installed in India – ONGC Gujrat, BHU Varansai, ISM Dhanbad etc. [Click here for more info]

FOCUS 35 robotic total stations are hard at work helping build the world’s largest expressway network. In one notable example, the FOCUS 35, with its time-saving automatic scan template, is checking the cross-section quality of the twin Nan Kunshan tunnels for the new six-lane Shazhan S14 regional highway. Excavation under Nankun Mountain for the twin tunnels, each 4.1 km long and each capable of carrying three lanes of vehicular traffic, began in September 2016. In the current second phase of construction, the FOCUS 35 is being used to gather data that will be used to compare the as-built tunnels to the design specifications to determine what adjustments to the tunnel surfaces may need to be made.[Click here for more info]
