What Array Is The Best?

Posted by Sean on Aug 14, 2019

 

We’ve gone over several electrode arrays and resistivity methods in a recent 11-part blog series. We’ve covered common arrays like Wenner, Schlumberger, Dipole-Dipole, Pole-Dipole, and Pole-Pole. We’ve also covered some uncommon array types like...

Bipole-Bipole Array: Electrical Resistivity Methods, Part 11

Posted by Sean on Jul 29, 2019

 

 

It’s been a long journey, but today we’re at the end of our 11-part series discussing Electrical Resistivity Methods. In this final discussion, we’re going to give you an overview of the Bipole-Bipole Array.  

Don’t worry though, we plan to do more loong-form series like this in the future about different topics!  

 

And if this is your first time joining us, you’re in for a treat because we’ve also covered all of the following methods:

EarthImager Demonstrations with Hasan Aktarakci and Eduardo Rodrigues

Posted by Sean on Jul 23, 2019

Throughout July, our Madrid office has been hosting webinars to demonstrate the basics of EarthImager™ 1D, 2D, and 3D. Some of our customers—especially those who signed up for webinar alerts—were lucky enough to attend the free webinars. There, they could ask questions and watch the hosts use the software in real time. We shared a lot of useful information during these webinars so we don't want to keep them hidden away! Below, you can find all of the webinars—including the ones hosted in Spanish.

Quick Tip: Improving Contact Resistance

Posted by Sean on Jun 21, 2019

 

Honestly, this blog post has been a long time coming. Why? Because “How do I improve contact resistance?” is probably one of our top 5 most asked questions from AGI customers. The question comes up in nearly all of our AMA Webinars, seminars, and troubleshooting calls. So we’re finally answering this question in the blog (and AGI Help Desk) so that you’ll always have the answer on hand!

Alright, let’s get into it.

Gradient Array: Electrical Resistivity Methods, Part 8

Posted by Sean on Jun 18, 2019

Today, we’re discussing the Gradient Array. Well—more accurately—the Gradient Arrays. The Gradient Array actually comes in two flavors, the Edge Gradient and the Strong Gradient. Fun fact, we recommend the Strong Gradient array the most to our customers. Why? Well, read on to find out!

 

By the way, this is the eighth article in our series exploring some common (and uncommon) electrode arrays.

We’ve also covered the following:

Quick Tip: What attracts animals to your ERI survey (and how can you stop them)?

Posted by Sean on Jun 11, 2019

 

Electrical Resistivity Surveys mostly happen outdoors. Of course you can perform small-scale tests indoors, but most clients aren’t going to give you such a comfortable project. So you’ll need to make your way outdoors into the heart of mother nature. And as such, you’ll be sharing your space with all manner of wildlife.

 

Some animals will shy away if they notice you working around their habitat. Others can be more curious—or attracted to some aspects of the survey.

Square Array: Electrical Resistivity Methods, Part 7

Posted by Sean on Jun 06, 2019

 

Welcome back to our series detailing the different electrode arrays that you may come across in your work. This is the seventh article in our series exploring 11 electrode arrays and methods. We’ve covered some of the standard arrays that will cover most of your bases. In the last post, we’ve started talking about some lesser known arrays. Today, we’re discussing another non-standard electrode array—the Square Array.
