In past articles, we’ve covered many ways industries apply Electrical Resistivity Imaging (ERI) for their benefit. From groundwater exploration to power engineering, and even archeology—we’ve shown the versatility of the electrical methods of subsurface exploration. But what if you don’t fit into one particular sector? Perhaps you’re a consultant or geophysicist for hire. For those who are looking...
We don’t discuss archaeology nearly enough as it deserves. And since it’s October and Halloween is around the corner—why not talk about the spookier side of geoscience? Okay, archaeology isn’t actually scary—unless you’re claustrophobic (the fear of being in tight spaces) or have cartilogenophobia (the fear of bones), or have mummyphobia (which is what we guess the fear of mummies is called).
But the real reason we want to discuss archaeology is that this year has seen several fantastic discoveries. This past Summer in our home state of Texas, a drought revealed...
We’ve discussed how Electrical Resistivity Imaging (ERI) has served many industries. We’ve covered mining, groundwater exploration, construction, and more. Let’s take a brief look at another industry—power engineering. We’ll explore how electrical resistivity methods impact power engineering projects, focusing on their practical applications...
We like to dig into various topics on our blog. One method that we want to drill into today is the borehole-to-borehole electrical resistivity survey.
We’ve broached the subject of borehole-to-borehole surveys a couple of times on our blog. We mentioned it in our post about the Bipole-Bipole array and our Panama seminar recap. The Panama case is fascinating because it utilizes our...
The beginning stages of any construction project can present various challenges that may affect its success. Addressing these issues early on, from site selection to budget constraints, is crucial. One particular concern is understanding the subsurface geology and potential anomalies that can impact construction. That's where Electrical Resistivity Imaging (ERI) comes in. This blog post will explore how ERI can be a game-changer in construction projects, ensuring informed decision-making, preventing delays, and mitigating safety hazards.
Groundwater is a favorite topic of ours here at Advanced Geosciences. There is just so much to discuss! Not only is groundwater exploration an everyday use of electrical resistivity imaging (ERI), but understanding groundwater can reshape our relationship with an invaluable resource. This time, we want to look at groundwater discharge and the delicate balance it serves on a global scale.
Underground aquifers are layers of sediments or fractured...
On our blog, we’ve covered 1D, 2D, and 3D Electrical Resistivity Imaging (ERI) surveys numerous times. We’ve made general comparisons and even compared how useful each is for groundwater exploration. One type of survey we don’t talk about is 4D ERI. Let’s talk about that today. So, what is a 4D ERI survey?
We’ve discussed groundwater several times on our blog and educational series. We’ve discussed how to find it and shared a few successful cases of finding it with ERI techniques. We’ve also compared 1D, 2D, and 3D survey types in a...
We’ve covered the ASTM G57 soil test and IEEE standard grounding test on the blog before. In many cases, these standards will be your go-to solution for your soil test/grounding project. However, in some cases—the ASTM or IEEE tests show too high values so grounding wells need to be installed for power systems. Dry and arid soils typically found in desert environments can often produce these kinds of results.
In order to get a more accurate reading of...
