Terrascan Pty Ltd

Last week, we imaged over 300 meters in a single day using our cutting-edge Acoustic and Optical Televiewers! Our purpose-built setups make rapid logging and deployment a reality across Australia. #geotech #construction #engineering www.terrascangroup.com.au 1300 884 198

Earlier this year, our 900m unit was deployed in Southern Victoria to conduct Acoustic and Optical Imaging. Over a two-day period, five boreholes were successfully imaged as part of this geotechnical investigation. #geotech #geophysics #engineeringgeology 1300 884 198 www.terrascangroup.com.au

Another successful day completed in QLD. Three boreholes to 35m imaged with Optical and Acoustic Televiewers, averaging 1.5 hours per borehole. #geotechncial 1300 884 198 www.terrascangroup.com.au

We have had a cancellation for the week of the 20th and our logging vehicle will be in Adelaide on standby. As a result, our Geologist with Geotechnical logging experience will also be available during this time. Please reach out if you're in need of Imaging or Geotechnical services between Adelaide, Melbourne and Sydney during this week. 1300 884 198 www.terrascangroup.com.au

We are frequently asked about the borehole conditions required for our Optical and Acoustic Televiewers. This article may help with answering some of these questions. Feel free to get in touch regarding your specific project challenges. #geotechnicalengineering

Full Waveform Sonic and Poisson’s Ratio for Geotechnical Investigations:   Under Suitable conditions the (FWS) tool is capable of recording both P (compressional) and S (shear) wave arrivals from boreholes with a minimum diameter of 60mm. The Poisson ratio can be calculated at 5-10cm intervals along the formation with a relatively short acquisition time especially if you’re already running other tools.   Like the Acoustic televiewer the borehole needs to be filled with water for the Ceramic-piezoelectric transducer to excite the formation. A tool length of 2.30m makes it one of our largest and heaviest tools that we carry.   To add FWS to your next downhole scope please contact us   1300 884 198 www.terrascangroup.com.au

Terrascan’s portable setups were mobilized last year, with over 20 boreholes imaged with Acoustic and Optical Televiewers inside the galleries of a dam in just a few days. Using two setups enabled us to complete the job within the very tight timeframe that was given. All 21 borehole reports were fast tracked, and all sent out over the weekend (at client’s request). Our fastest turnaround ever. #geotechnicalengineering

Seeing Beyond the Surface: Unleashing the Power of Acoustic and Optical Televiewers. Acoustic Televiewers (ATV): Imagine a powerful ultrasound probe, sending sound waves into rock and capturing their echoes. ATVs paint a 360° detailed picture of fractures, cavities, and bedding planes, even through cloudy water. In the right conditions they can be used to image behind PVC casing! Optical Televiewers (OTV): A High-resolution 360° camera for boreholes. They capture high-definition images of rock walls revealing lithology, fractures, faults and their orientation. Critical for assessing stability and potential hazards. Get immediate on-site data enabling quick decision-making and adjustments for packers, VWP placement and well installations. For difficult sites, our portable setups can be carried in when there is no vehicle access. Ready to unlock the power of subsurface visualization?
