AGI will be at SAGEEP 2018

Posted by Sean on Mar 19, 2018

We’re packing our bags and heading to Nashville next week to attend SAGEEP 2018 (March 25th-29th). We’ve been working hard on a new product—and we’re excited to announce that we’ll be unveiling it at the show! We hope to see both familiar and new faces (Oh, and to try some Nashville-style hot chicken!)

The Benefits of a Weak Dollar

Posted by hasan on Feb 27, 2018

 

Let’s face it, no one wants to hear that their currency is weak—especially Americans who may not want to hear that, as of right now, the US dollar is weak and the Euro is on top. But what if we told you that having a weak dollar was a good thing—not just for Europeans, but for American businesses as well?  Ok,...

Pole-Pole Array: Electrical Resistivity Methods, Part 5

Posted by hasan on Oct 06, 2017

Electrode arrays are different arrangements of electrodes used to perform geophysical resistivity measurements. Electrode arrays were developed in order to make field measurements more efficient and data interpretation easier.

Today, we’re discussing the pole-pole electrode configuration—this is the fifth article in our series exploring 11 electrode arrays and methods. We’ve also covered the following:

Pole-Dipole Array: Electrical Resistivity Methods, Part 4

Posted by hasan on Oct 06, 2017

Electrode arrays are different arrangements of electrodes used to perform geophysical resistivity measurements. Electrode arrays were developed in order to make field measurements more efficient and data interpretation easier.

Today, we’re discussing the pole-dipole array—this is the fourth article in our series exploring 11 electrode arrays and methods. We’ve also covered the following:

Posted by hasan on Oct 06, 2017

Electrode arrays are different arrangements of electrodes used to perform geophysical resistivity measurements. Electrode arrays were developed in order to make field measurements more efficient and data interpretation easier.

Today, we’re discussing the dipole-dipole array—this is the third article in our series exploring 11 electrode arrays and methods. We’ve also covered the following:

Schlumberger Array: Electrical Resistivity Methods, Part 2

Posted by hasan on Oct 06, 2017

Electrode arrays are different arrangements of electrodes used to perform geophysical resistivity measurements. Electrode arrays were developed in order to make field measurements more efficient and data interpretation easier.

This is the second article in our series exploring 11 electrode arrays and methods. We’ve also covered the Wenner array. Today, we’re discussing the Schlumberger array.

 

What is the Schlumberger array?

The Schlumberger array is an array where four electrodes are placed in line around a...

Wenner Array: Electrical Resistivity Methods, Part 1

Posted by hasan on Oct 06, 2017

Electrode arrays are different arrangements of electrodes used to perform geophysical resistivity measurements. Electrode arrays were developed in order to make field measurements more efficient and data interpretation easier. In this series, we’ll explore 11 electrode arrays. The first array we’ll discuss is the Wenner array.

 

What is the Wenner array?

The Wenner electrode array is the simplest of arrays; in it, the four electrodes—A, M, N, and B—are placed in line and spaced equidistant from each other. The two outer electrodes, A and B, are current electrodes,...

A Comparison Of 11 Classical Electrode Arrays

Posted by hasan on Oct 06, 2017

Electrode arrays can be defined as various arrangements of electrodes used to perform geophysical resistivity measurements. These arrays were developed before computers and modern algorithms were available in order to make field measurements more efficient and data interpretation easier. Even with today’s automatic resistivity imaging instruments, these arrays are still used in order to ensure an even coverage of data points.

There are a number of different arrays, but only a few have been important and frequently used. These include the Schlumberger array, the Wenner array, and the...

The Streaming-Potential Method: Its 2 Main Uses

Posted by markus on Feb 28, 2017

Streaming-potential (SP) is an electrical surveying method used when fluids or electrolytes—typically water—move through porous areas in the the ground. This creates a change in voltage that can be read using a voltmeter and two electrodes. Streaming-potential is synonymous with “self-potential” and “spontaneous-potential,” though the latter two designations are used when the cause of the spontaneous voltage is chemical processes associated...
