Good Friday morning everyone. TGIF.
Sid, this is just one of the four sites they were doing. It is just part of the site. This one has two rows of trucks, 6 on each side. The trailers are full of expensive gear. No doubt they spend a bunch of money on each well. And they don't do it for fun or as a hobby. That well will be pumping a lot of hydrocarbons out of the ground.
The first fracking was done in the 1800s but modern fracking really started in the 1940s. It is a very mature industry.
