| Oil Extraction Facts in Questions |
Oil Extraction? I have an interview tomorrow and they are going to ask me about the oil and gas industry. A brief overview of the extraction process of crude oil, and other process's involved (namely on offshore locations) would be greatly appreciated.
The job is for an apprentice mechanical techinician.
thanks gazi r replied: "Check my brief explanation in one of your previous questions"
Stuart C replied: "oil is produced from platform or subsea wells. The effluent (oil, gas & water) flows through a "christmas tree" which has many valves fitted to it, the main ones are the downhole safety valve, master valve and wing valve. From here the effluent is routed to either a test or production separator. Inside the vessel there is a deflector dish to help separation by changing the pressure and direction of the effluent. Straightening vanes, mist pads, and coalescing pads help dry and direct the gas. Most importantly there is a weir. The oil sits on top of the water and spills over the weir under level control. The gas is then dried and compressed, the oil is routed to the storage vessels or cells. The water is sent overboard or back into reservoir. Two separators can be used in series to aid the separation. It is a lot more complicated than this with lots more info but its a start as the whole thing is a too long to write here. Hope this helps, good luck" What solvents should be used for oil extraction? I read that the use of solvents in oil extraction in seeds and plants yields more product. But I don't know what solvents to use for oilseed extraction. Help please. Thank you very much! ^_^ Medical Doctor replied: "you could use 95% ethanol. Since it has a hydrophobic property, it binds with the oils. Also since the oil is hydrophobic one, it goes with the scientific quote saying: "Like dissolves like""
A.V. R. replied: "There seems to be some mistake. Ethanol is completely miscible with water in all proportions. Otherwise how can one have a whiskey and water? If any thing, it is quite hydrophilic.
Probably it was trichloroethylene or such chlorinated solvent that was meant, which are also used for solvent extraction.
Ketonic solvents are quite suitable and used in the industry. Acetone is the first of the series. It also boils at a low enough temperature so that solvent recovery without heat damage to the oil is easy."
milton b replied: "First, solvent extractions of anything are not something you should be attempting at home. Solvent extraction can be a dangerous, messy process. The most commonly used solvent for commercial fat extraction is hexane. Acetone is not a good enough solvent and chlorinated solvents cannot be used because they are carcinogenic. Although hexane has some toxicity the concentrations in the extracted fats are too low to be a significant health threat. The other advantage in hexane is economic. Hexane is relatively cheap and it has high volatility so that recovery and reuse of the solvent makes it economically attractive." Does oil extraction from the Earth cause earthquakes and Tsunamis? I heard that removing pressurized oil and gases from the ground causes the plates to shift positions. stl_luna_7 replied: "No.. they don't. It is caused by plate techtonics."
scottsdalehigh64 replied: "No. So far, there is no evidence for any man-made activities that change plate tectonics, the cause of earthquakes. Tsunamis can be caused earthquakes or avalanches, but no oil drilling has been shown to cause these, so far."
Craig O replied: "Good question!"
Loren S replied: "i doubt that but even were it so do you think the big oil companies would let that information get out."
jim z replied: "There were some cases where pressurized water injection caused earthquakes by hydraulically separating to fault boundaries resulting in slippage. Removing pressurized oil and gas would have very little effect. It is possible to trigger an earthquake I suppose, but it would not build up the necessary stresses to make a sizable quake."
mithun k replied: "No not at all, untill you try some Hydrogen bomb to drill out the oil." The earths weight is decreasing due to oil extraction? If we are extracting oil and other natural resources out of the earth, doesnt this technically decrease earths weight? If so, what effect does it have it on the earths gravitational pull? With the amount of oil that is being extracted and water that is being dried up, in theory wouldnt this have an effect? Erik R replied: "I wouldn't think so cause 1) the earth is freakin' huge and 2) all that carbon dioxide and water vapor is going into the atmosphere. Hardly any goes into the vacuum of space."
Stop and stare replied: "if oil is being dried up....hmmm..i think that will an end of the world..."
saphty2000 replied: "Are you relating this to GMM/R^2?
"
Zepman replied: "Nah, all that burned up oil is falling on my car and making it dirty... bastards... Time for another car wash...."
Margrave replied: "Well, no. the mass is still in the system, just mostly in the atmosphere. There are losses from the atmosphere which are immediately made up because the orbit of earth is a very thin gas torus, and the gas shares the same orbit.
Now as the polar caps melt will that have an effect? For the arctic, no because the ice is already displacing water, but for the antarctic, yes there will be a sea level rise, perhaps 8 to 10 meters. redistributing all that mass away from the axis of rotation WILL have an effect on another system, the length of the day.
And that effect may in turn generate a new age of vulcanism."
Hadi Abulughod replied: "oil isn't holding the earth in place. wouldn't the same theory go for the extra things that are being created (ex. cars, planes, buses, etc.)"
MR.QA replied: "yes, some thermal energy is lost in the system when you burn the fuel when you convert oil to energy.
minimal effect on earths gravity pull since the earth is so massive. even if you dry up the oceans you hardly effect gravity. by conservation of momentum, in theory if you jump, earth also moves away from you, but you really see earth not moving.
yes, in theory, maybe to the 1 millionth decimal place. you will still use 9.81 instead of 9.8100000....1 in your physics problem." Where can i find a list of crude oil extraction/production? Histories,countries and avarages.? I am seeking to get an average of global extraction , year by year to do some comparisons geo.karma replied: "You can find that information here:
Cheers." What fills the void we leave after oil extraction? And what effect does this have on our environment, global warming, etc.? Cirric replied: "Hi. Water or steam is pumped into the well to 'float' the oil to the top, I believe. "
Demonus H replied: "Some believe that Earth actually produces Oil. It is not a fossilized fuel and wells in Long abanonded Texas Oil fields are filling up again"
dont know much replied: "raw sewage I think"
kenai_sailor replied: "depends on the oil reservoir. usually oil is trapped in interstitial spaces that are essentailly gaps in sand/rock. usually they are not completely emptied, but in any event, those gaps remain, but may later be filled with sub-surface water. no effect either way on momma earth"
tlbs101 replied: "Sometimes nothing fills the void.
Sometimes companies pump high pressure salt water down the well, to force more oil to the surface. They leave the salt water down there.
Just leaving an empty oil well, or one filled with salt water has little impact on the environment -- in of itself.
After wells run dry, sometimes they cap the wells off with concrete, but that's not always the case.
----------------------
I answered you question as it was worded, but...
THIS might be what you are looking for:
When they DRILL a new well, laws require that concrete (grout, actually) lines the walls of the well hole wherever drinkable water exists underground, to seal the drinking water off from contamination.
Example: the oil well is 2000 feet deep, but there is drinkable water at 200 feet. The drill company drills down to 300 feet and pumps grout into the hole, lining it. They wait for it to dry, then they continue drilling down to the oil at 2000 feet. When the oil comes up, it won't get into the drinking water supply.

JOHNNIE B replied: "It is filled with salt water ,and there is no green house gas."
Thinker Paul replied: "SIN!!!" Ecologically friendly solutions to oil extraction? The issue of ever-rising gas prices and the constant search for new sources of oil and energy is an important issue worldwide, and is of particular importance in North America, both physically and politically. Across North and South America there are various reserves of oil sands, such as the Athabasca Oil Sands in Alberta. There are many negative environmental impacts to draining these sorts of oil reserves. Propose alternative ecologically friendly, economically feasible, and sustainable solutions to this type of oil extraction.
if anyone could get me started on this question, to help start my discussion! thankssss David W replied: "Hope these may be useful links-" From where i can get the information about soybean oil industries?
