So yeah, shot holes. The geophysicist must be a young'un.

P.S. The 'expert' that said any marks would be removed after a seismic survey is surely pulling someone's leg. He likely has never met either juggies or drillers.
I learned right off to pay attention to the tool pusher. Those guys ranked next to the all-mighty when you were making hole. When they say jump, you best jump.Foy said:Never met juggies or drillers- ain't that the gospel truth.
My deaf drillers could only hear one thing---thunder. With up to 300' of steel in the ground and a 30' mast above the surface, and no safety grounding, our SOP was to come out of the hole and lay the mast down at the first sign of an electrical storm. Good old Ed, who probably hadn't heard a conversational word in years, could hear the low frequency sound of thunder a good 30 minutes before the rest of us. We all thought he was sandbagging to get us to call a rainout until we realized he was right the great majority of the time. When Ed heard thunder, the storm would show up a while later. We used the three drop rule to call a rainout: when weather threatens, draw a circle in the dust on the truck's hood. When the 3rd drop lands inside the circle, it's time to go to the house.
Doddlebugging for a living, in whatever form, was, to steal a term from Ray Wylie Hubbard, cooler 'n hell.

When running a seismic line, there is an array of receivers deployed to pick up on the shockwave vibrations created by the propagator of the waves. In the beginning, dynamite was used to create the waves, thus requiring the drilling of numerous fairly shallow holes called shot holes. Nowadays, "thumper trucks" are used. Thumpers travel together in twos, threes, or more, and at carefully spaced intervals, a big pad deployed from under the truck raises the entire truck a few inches off the ground and an oscillating device within it blasts vibrations into the surface beneath the pad. The receivers referred to above are called geophones or jugs and they are deployed by the hundreds to thousands along the line of planned shots or thumpers to pick up the reflected waves from the shots. The jugs are placed into shallow scraped spots right at the surface, just below any organic matter/tilth. The geophones are electrically connected with one another by miles of lightweight cable and the connections all lead to the receiver apparatus located in a buggy, a truck, or a small shack helicoptered in to a point along or close by the line. Wherever the receiver apparatus is located, it's called the doghouse. To deploy and pick up & move the many geophones and their cables requires lots of manual labor from jug-runners, or juggies. There was not a great deal of academic rigor behind the training needed to carry huge coils of cabling, dozens of jugs, and lay them out along the line in the shallow scrapings, but a considerable degree of strength and stamina was needed to do so over hill and dale, mesa and butte, in all kinds of weather. Enter the late teens/early 20s outdoors-loving hippies of Tony's and my field days in the late 1960s and early 1970s: Crews of a couple or three dozen juggies putting them down and picking them back up, dozens of miles or a helicopter ride from base camp or town, through very long days. They were the type locality for "work hard, play hard". You didn't want to stand idly in between the juggies and the beer at the end of the work day. They'd run your butt right over.craig333 said:I was kind of hoping for a dictionary myself
We used Israeli Command Cars, painted blue, for a 7 month job in NW Kenya. And French Alouette helicopters. Blue looked like UN colors, so the bandits and camel rustlers would leave us be.Foy said:especially if you like seeing what old era off-highway vehicles looked like 50-60 years ago.

I am sure Foy and I would be happy to share, but part and parcel of that experience would be your need to wear at least hip waders, if not chest waders. Two geologists telling stories is guaranteed to serve up at least 3 versions of every event or 'known fact'.Ted said:Catching up on WTW and this has been very interesting. Would love to be in camp with Foy and Tony just to hear the stories.
Dang, Tony, don't go and show them the secret handshake! But yeah, I'd say chest waders would be best.AWG_Pics said:I am sure Foy and I would be happy to share, but part and parcel of that experience would be your need to wear at least hip waders, if not chest waders.
