Mt Sopris Hosts GroundTruth Exploration Training in Denver, CO

GroundTruth Exploration, a top-tier mineral exploration service provider, is focusing on bringing geophysical borehole logging services to their ever-growing expertise on geophysics! To complement their logging system equipment, four members from the GroundTruth team visited Mount Sopris Instruments in Denver, Colorado for two days of comprehensive training to master their logging system equipment and WellCAD software.

Training Day 1:

On the first day, the team engaged in extensive training on the MXA Winch with ScoutPro and Matrix Data Loggers in addition to the Optical Televiewer and Acoustic Televiewer (OPTV/OTV and HRAT/ATV respectively). GroundTruth trained on the 200 ft deep test well at Mount Sopris Instruments where all team members could practice setup, data acquisition, and takedown on the test well in a safe learning environment. Key takeaways included: – Winch Maintenance: Checking winch settings for accurate deployment and communication from the wireline to the tools.

**Pro Tip: The wireline should often be tested for electrical integrity with an ohmmeter, capable of measuring resistance of at least 20 Mega Ohms, perhaps before beginning each day’s logging and particularly if there is any problem with tool operation or communications.*- Logger and Televiewer Settings: Setting the correct winch direction and configuration of the tool stacks for the OBI and ABI televiewers.

**Pro Tip: Use the down log run to test your acquisition settings are optimal for the borehole environment (exposure for the OBI, or azimuthal resolution for the ABI). The up log has the best depth data since the wireline tension is greater going up hole.*- Logging Best Practices: How to safely set up the logging system, ensure good wireline signal communication, and effectively collect data.

*Pro Tip: Never support the tool on its optical or acoustic head as that is the weakest part of the tool and be particularly careful to avoid scratching the optical window. Check O-Ring seals and apply silicon grease before re-assembly. It is strongly recommended to inspect the integrity of the glass sleeve before each run. Never immerse the tool in a borehole if any defect or crack is visible to avoid irreversible damage to the tool.

Training Day 2:

On the second day, the team was able to put their learned skills to the test and collected televiewer data logs in our test hole. During this training, the team had a chance to ask questions related to application, varying borehole conditions, and practice “what-if” scenarios so they are fully prepared for field trials and troubleshooting! Furthermore, we used the data collected to train the GroundTruth team on WellCAD basic software and the Image and Structure Interpretation (ISI) workspace. Key takeaways included: – Trouble-shooting: Checking logger settings, cable connections, and power.

** Pro Tip: Inverter Warning: When using a DC inverter to power the winch, a true sine-wave inverter is required for smooth winch operation. Minimum power requirement from such an inverter is 600 watts, which should also allow the operation of the logger.* – Data QC: Pulling the data into WellCAD and ensuring it is complete and accessible.

• Image and Structure Interpretation: Fracture analysis and visualization both in 2D and 3D.

In conclusion, we are thrilled for the GroundTruth team as they take on geophysical borehole logging and wish them great success in their operations! It was a pleasure to host our friends at Mount Sopris Instruments in Denver, Colorado so they could receive in-depth technical training, prepare for their upcoming projects, and meet our team of excellent engineers and technicians.
