Dana Jurick, Chief Operating Officer of Neubrex Energy Services US LLC. discussed the collection, analysis and interpretation of strain measurements utilizing fiber optic cables.
Rayleigh Frequency Shift Distributed Strain Sensing (RFS-DSS) is a powerful technique for measuring strain changes along the entire length of an optical fiber. It utilizes the Rayleigh backscatter phenomenon, where light pulses sent through the fiber are scattered back by microscopic refractive index variations within the core. Those variations are natural variations in the glass optical fiber inside the fiber optic cable that is clamped to outside of casing string, cemented in the annulus and thus coupled to the formation and wellbore structure.
Overall, RFS-DSS is a versatile and powerful technique for distributed strain sensing, offering high spatial resolution, long sensing range, and real-time monitoring capabilities. Its advantages of cost-effectiveness, ease of installation, and immunity to electromagnetic interference make it a valuable tool for various applications in infrastructure monitoring, geotechnical engineering, and the Energy exploration, production and development industries.

*** I have a hotlink here – I’m going to show this one video after I watch the commercial. I’m going to skip – (Start Content) I’m going to show you guys an Olympic track race that is kind of interest. If I can turn my sound on here. This is a 100m track race at the Olympics where Usain Bolt was running. If we watch the race take place, I’m going to come up here to 7 minutes, 7:30, we’re going to watch the race in slow motion. So here is the start of the race – this is like multiple fractures taking off from the injection well moving, propagating forward towards the observation well. And you can see that in each lane, there are various runners that cross the plane of the finish line at different times. So, this is like fractures propagating at different speeds towards the observation well. And why this is important because they’re going to show you here in a minute on how they determine the place finishes for all of these runners right there. And I’m going to stop right there. ***

The heat beneath our feet flows through the earth in a complex pattern. Utah FORGE is situated in a heat reservoir that has been studied since the 1970s. In this webinar, Dr. Stuart Simmons delves into the unique geologic and geothermal resources found at Utah FORGE and the surrounding area.
What exactly are the rock types that make up the underground laboratory of Utah FORGE? In this webinar, Dr. Clay Jones describes the geology of the site and surrounding area and the findings from core and cutting analyses of deep wells!
Dr. Kristine Pankow of the University of Utah has been named the Geological Society of America’s 2025–2026 Distinguished Lecturer. Her lecture, “Utah FORGE: A Field-Scale Geothermal Laboratory,” will spotlight groundbreaking research at the world’s only dedicated site for advancing Enhanced Geothermal Systems.
