There is an oilfield museum in Santa Paula, CA that I have visited many times. Oil wells from as early as the beginning of the 20th century were pretty common where I grew up. That museum documents a lot of the early exploration and drilling. I found it fascinating.

I haven't lived in that area since 1963, though, so I haven't been in that museum since then. Here's its website:

If you ever find yourself on Highway 126, stop in and visit the museum.
