yep, we're In the "patch" as you call it.
Around here, it's the "OilField" on call 24/7
Here's a pic of our pressure testing unit.

The trailer is (in the pic) a 20K Tandem axle Dual Wheel 25' Gooseneck.
The Fiberglass tanks usually carries fresh water, but can carry Salt Water, or "Gel", and any thing else that doesn't eat fiberglass.
The Motor is a Detroit 6-71. A two stroke, with only 6 valves total.
(If you ever get the time,, Look up how a two-stroke Diesel works, it's Different and cool!) This motor has gone into 40,000 Hours running time. (without rebuild) and about 3-4 oil changes, 5 gallons each.
The Detroit turns a "Tri-Plex" water pump. (it has 3 "plungers")
The water pump is rated for a working pressure of 15,000PSI.
We also have Hydraulic Nipple up equipment for Tightening down gas wells, a working pressure of 30,000Lbs. (Usually only go to 2K)
My Dad started his company back in '91. Pulling the same trailer in the pic, with a '91 Dodge 350 Cummins 5-speed 2wd.
We then had a '96 3500 Cummins 5-speed,
and then a '98. 5 3500 (Which is my truck now. )
The Chevy,, well, isn't doing as well as we thought,, although it Pulls FASTER (Higher MPH) than our Dodges,, It doesn't pull better.
We are a little wooried about the oilfield industry as the companies that contract my Dad, are waiting to see wether the war is gonna make a "Boom" or "Bust". SO pro-duction is very low. There is SO MUCH GAS out there from when the Airlines shut down. I've heard about 10 Billion EXTRA gallons (Or was it drums?

)of fuel that would have been used,, now just sitting, making the demand drop horribly.
Our Company is Called "Merricks Pressure Testing" and our main goal is to provide a safe working enviroment. We test Gas and oil wells,, including pipelines for any leaks.
