I work in oil and gas. Have for 10 + years now. Specifically directional drilling. See the drill bit needs to be steered in order to hit certain targets/ pay zones laid out by geologists and engineers. We steer the bit by relying on mwd (measurement while drilling) tools. This is my area of expertise. These tools give you azimuth (direction), inclination so you can calculate build( vertical vs horizontal) as well as gamma readings so you know what formation you're in. I drilled salt water disposal wells for 5 ish years. Drill a well then pump it full of salt water excess from other wells. These wells are ALL over Oklahoma. About 2010 or so Oklahoma started experiencing "freak" earthquakes. We don't have a history of earthquakes. The oil industry tried saying it was all natural and that the wells we were drilling had nothing to do with the quakes. Lies, straight lies. You can't pump thousands upon thousands of gallons of water into the earth and expect nothing to happen. I've been on active drill sites when earthquakes happened. What we were doing to the earth is a DIRECT result of those earthquakes.
I hate the industry I work in. I love this earth however I can't pay the bills working the trades. I tried as an electrician but it's not a liveable wage. Anyway cause and effect ya know
Sorry for the rant
