: The electric motor or gas engine at the surface that provides the raw mechanical power.

Before these mechanical marvels took over the landscape, extracting oil was a messy, inefficient, and often dangerous guessing game. oil_pump_schematics.part3.rar

If you were to extract "Part 3" of an actual oil pump schematic, you would likely find the detailed engineering drawings of the and the sucker rod string . : The electric motor or gas engine at

When the pump arm nods down, the traveling valve pushes down. The pressure closes the standing valve (so oil doesn't push back into the ground) and forces the traveling valve to open. The oil passes through the traveling valve, ready to be lifted to the surface on the next upstroke. ⏳ A Century of the "Nodding Donkey" When the pump arm nods down, the traveling valve pushes down

: In the late 19th and early 20th columns, oil strikes often resulted in massive "gushers." While cinematic, they wasted thousands of barrels of oil and posed massive fire hazards.
