Oil Definition and 552 Threads

Hi, I had come to a university hoping to study Petroleum Engineering but they said what they teach is Oil and Gas Engineering. Really I do not know more about the differences if there is because petroleum implies oil and gas. But, there should be a reason why it is called that way and not PE...

I know that some peanut doesn't have oil separation, but this is due to emulsifier chemicals that are added. I'm wondering what causes the oil to be released. I assume the storage structure is ruptured, and the oil molecules are consequently released. What exactly is a peanut? It's not a...

l am trying to use used oil to gasoline engine l make geet reactor to vaporized petrol diesel but no success to oil how can l convert used engine oils and food oils to gas or flammable liqiuds thanks jonathan

I completed the Millikan oil drop lab in class with as much accuracy as possible. I used the PASCO interface and used a very accurate Air pressure calibration. My final experimental charge of the electron derived from the equation in the lab was, 1.8 x 10 ^-19 C. When I turned in my lab, I was...

I am not talking about drive mechanisms used in oil extraction, like water or gas injection. I am referring simply to the fact that oil migrates to the top of reservoirs until it reaches an impermeable top layer that traps it. "A trap forms when the buoyancy forces driving the upward migration...

I am coming close (~1.5 years remaining) to finishing my undergraduate degrees (chemical/process engineering and finance), and have pretty much decided that I will work in the energy industry. I live in Australia, so there are definitely plenty of opportunities at the moment for me to find work...

Lubrication -- is fine machine oil "better"? So there is always a debate on gun forums over if lubricants marked for firearms are better then motor oil or cheaper automotive lubricants. I'm curious if anyone here has any hard information on the differences and what is better?

My new Civic recommends 0w 20, however it is a bit more expensive, especially if done at a dealership. Is there much difference between 0w 20 and 5w 20? I heard the only reason Honda uses 0w 20 is to meet the MPG guidelines.

How often do you change the oil in your personal car, truck, or other transportation device? Why did you decide on that frequency? Do you do anything out of the ordinary to extend the frequency? (Special oil and/or filter?)

Why would major oil companies like Shell, Schlumberger and Exxon Mobil hire physics graduates and physicists? So I'll be starting my physics degree course this fall and I've heard plenty of people saying that a physics degree would definitely open doors to careers at oil companies. I don't...

So I've been trying lots of different olive oils, all extra virgin so far (it's the most common olive oil here in Argentina). Usually they have a weak taste and for some of them, it's even hard to say I can really feel the olive taste. The other day I bought a 3 times less expensive than...

Is there any truth to Peak Oil being a myth? Skeptics are claiming that oil is not made from previously living matter and therefore shouldn’t be considered a fossil fuel. They mention the deepest fossils ever discovered have been no more than 16,000 feet yet we drill for oil in depths much...
