At the end of January 2022, Joanna Holmgren and Max Werner from Bristol University and BGS’ Jon Chambers visited the UK Geoenergy Observatory (UKGEOS) in Glasgow to conduct a small seismic borehole survey at the abandoned coal mines that have been repurposed by UKGEOS for geothermal research.

The aim of the fieldwork was to see how well an emerging seismic monitoring technique called distributed acoustic sensing (DAS) performs in a shallow, urban geothermal setting. Over three days, the team from Bristol University recorded DAS down a 90 m-deep borehole, deploying hydrophones alongside the fibre-optic cable as a benchmark.

For further information about the project and a seek peak at the initial results refer to the UKGEOS blog post

WellCAD V.5.5 - New Release!

This new version of the WellCAD software has been updated to include a number of new features and upgrades. This involves changes to the image & structure interpretation package with Linear structure picking, Partial picks, Terzaghi correction and revised Borehole imaging (BHI) import.

These will allow the user to better image core linear structures and lineation’s and interactively pick the orientation, present plus classify structures. Partial picks allows individual or multiple selection of visible segments in the sinusoid to derive the depth of the planar feature/eroded bedding plane. The software’s statistical analysis functions have expanded, allowing the user to analyse the structural picks along the borehole axis, providing a weighting factor on the acute angle between the structure and axis (Terzaghi correction). BHI tools replace the FMS/FMI import wizard enabling tool configuration adaption to the imported data channels allowing you to view the data prior to final conversion with fast and easier processing.

The Basic module and flowmeter workspace has  upgraded functions which improve the data analysis.  The main highlights include CoreCAD (new lithology dictionaries), WellCAD workspace expansion, Spinner flowmeter calibration, Flow velocity plus bulk flow process and flowmeter workspace improvements. Essentially, these will allow the user to assess the speed and spinner frequency curve and supply a linear regression in order to obtain a calibration model which is automatically saved. The flow velocity and bulk flow process allow the user to compute flow velocity from measured spinner frequency data and compensate for logging speed. The workspace can handle in-flow and out-flow situations - with a new simple SHIFT + left click function.

There are many more features including the fullwaveform sonic module for cement bond index and compressive strength process (signal attenuation comparison in partially cemented zones)  along with the automation module for the integrated script editor (visualisation of Visual Basic Scripts). There are further developments to enable python script support later in 2022 known as pyWellCAD although a beta option will be available in WellCAD 5.5.

Please note that ALT will be hosting a number of free webinars in the upcoming week to highlight these new features - These are free webinars which are around 30-45minutese each, please register your interest!

As of the start of 2022 Georadis has released the new upgraded RT30-MKII Isotope Identification meter.

Manufactured by Georadis, the RT30 MKII has all of the functions of the RT30 although has a larger sun readable display ensuring the readings can be read easily whilst in the field, its new design ensures all of the electronics are enclosed in a compact, easily portable handheld device. This Isotope identification instrument is designed for field use allowing the user to collect a number of measurements from samples and can be used in a number of applications which include waste/ scrap metal recycling, research labs and production facilities. Its scintillation detection probe uses a photomultiplier tube with up to date silicon photomultipliers technology and a larger detector. 

As with the previous model the RT30 MKII integrates a radiation survey, dose meter and radionuclide identification in one compact device and has automatic stabilization on natural background radiation throughout its operation.  The meter has an  ARM  processor and a programmable array (FPGA), this combination allows the meter to handle other sensors at the same time as the gamma ray section (Geiger-Muller counter and Neutron detector - standard offer). It is capable of holding multiple detectors with a maximum detector size of 2” x 2” or 5” with silicon PMT (SIPM or MPPC).

The RT30 MKII can support existing as well as new communication standards with wide compatibility, it is Bluetooth enabled and has its own built in GPS unit for time synchronization,  allowing both recorded measurements and GPS measurements to be stored. With an increased sensitivity and a robust design this is an ideal instrument for field geology/ mapping and radiological studies and can also be used in harsh environments. 

We look forward to providing you with some further information on the GT30 and GT32 MKII which are coming out later this year mid-summer. These new devices will be suited to more geological and core sampling applications.

Geomatrix are really exited to be receiving a Loupe mobile TEM system from Australia next week. This innovative system allows for TEM soundings whilst walking along, with no need to stop to take a measurement and will be available for demonstration survey and rentals.

Geomatrix a please to announce we have added a Raptor 45 system to the rental pool. The 8 channel system with 450MHz central frequency antenna expands our range of ImpulseRadar GPR systems. Optimised primarily for utility detection the cart based system offers a swath width of 0.64m,
