Petroleum Engineering: The physical and the chemical factors that control the oil bank formation

The oil bank is the part of the oil reservoir where the saturation of the oil increases due to the enhanced oil recovery methods that are applied to the reservoirs. The formation of the oil bank is necessary since it facilitates the collection of the oil from the fields later. The  more the number of oil banks in a particular field, the more is the ease with which the oil can be collected from the reservoirs.  Without the formation of the oil banks, the collection of the oil becomes difficult; since the oil drilling and the recovery processes cannot be carried out through the vast expanse of the whole oil field.   Continue reading

Importance and applications of Isotopes

Isotopes are two forms of the same element which differ in the number of neutrons present in the nucleus of a single atom of the element. There are 90 naturally occurring elements with roughly 250 stable isotopes and over 3200 unstable or radioactive isotopes. Different isotopes of the same element often have completely different properties, making some of them invaluable to mankind. Continue reading
