Seismic Crew Ahead

Have you seen these signs around?
Not only have they been ahead, they have been behind, above and all around us the past several weeks.
Workers are everywhere!
Walking through pastures.
Driving down the roads.
Driving in the pastures.
Flying in helicopters.
It's like a bee hive in our area!

What are they doing, you ask?
SEISMIC!
Basically, they are searching for oil.
It's been a really neat process to track!
The helicopters drop these bags filled with equipment and sensors.
The sensors looks like this.

There are cables, running off a sensor, buried into the ground. 

Then these monster trucks arrive!

THREE OF THEM!

They drive through pastures...
leaving these paths...
At least now we know where to cross the draw.

This part of the truck is the thumper.
The operator lowers it to the ground and according to "Seismic Source"
THIS is what happens.
"Thumper’s advanced technology what we call AWD "Accelerated Weight Drop" seismic energy source, where a high pressure gas (min 6.9 MPa (1,000 psi)) is used to accelerate a heavy weight Hammer (5,000 kg) to hit a base plate coupled from a distance of 2 to 3 m, which is coupled to the ground to generate an acoustic pulse. Several thumps were stacked to enhance signal to noise ratio."

I was able to capture a few videos too!
Excuse my finger in this one.

Then there is this one.
We were just across the fence line while taking the video and could feel the vibration.
Then just like that...
They are gone!
