The oil below the oceans must habe been well encased from the water to remain pure. After we pump it out, will it be replaced with water, or do we just have large air bubbles down there now ?
If it is air, is it possible that the bubble could collaps one day and create problems?What replaces the oil and gas we harvest from below the oceans ?
Actually the oil comes to surface under its own pressure, we only use water or gas to 'lift' the remaining oil out. When we have extracted all the oil that is possible out of the reservoir, the water that is down there natually fills in the pore space that was once occupied with oil.
If its air (just for the purposes of your question), it will not collapse if sufficient air is there at sufficient presssures to occupy the pore space where the oil originally was.What replaces the oil and gas we harvest from below the oceans ?
some oil companies have been pumping in waste products like carbon dioxide. it has been put forth as a possibel solution to releasing green house gases into the atmosphere. however, it would be costly and the long term effects are not known.
salt water is pumped into the drilling hole to float the oil and exract it easily. it replaces the former oil pocket
