1. Which type of oil is obtained by the distillation of paraffin base oil?
a) Lubricating oil
b) Kerosene
c) Vegetable oil
d) Diesel
Explanation: Lubricating oil obtained from paraffin wax usually has lower specific gravity and higher viscosity index than that obtained from asphaltic base oils. Also, more solid waxes separate from the paraffin base lubricating oil on cooling.
2. Which kind of oils contain asphaltic, naphthenic and aromatic hydrocarbons?
a) Paraffin base oil
b) Asphaltic base oil
c) Mixed base oil
d) Other oils
Explanation: Asphaltic base oil consists of non-paraffinic hydrocarbons such as aromatic and naphthenic hydrocarbons. This oil on distillation leave behind asphalt and bitumen.
3. Mixed base oil does not act as an intermediate between paraffin and asphaltic base oils.
a) True
b) False
Explanation: It acts as an intermediate between paraffin and asphaltic base oils producing varying proportions of asphaltic, naphthenic and aromatic hydrocarbons. It does not produce bitumen on its distillation.
4. Which of the following area contains crudes of mixed base oils?
a) Ankaleswar
b) Cambay
c) Naharkatiya
d) Mumbai
Explanation: The Naharkatiya oil fields in Assam contain crudes of mixed base oils. The Ankaleswar and Cambay oil field present in Gujrat mainly consists of paraffin base type. Extensive exploration of oil in all prospective sedimentary basins of India is in progress
5. How much percentile of petroleum is present in India?
a) 20%
b) 10%
c) 5%
d) 1%
Explanation: The Indian resources of petroleum are estimated to be around 300 million tonnes. The total world reserves of petroleum are around 30000 tonnes which are mainly present in the gulf regions
6. Which of the following deltas of petroleum are found recently in India?
a) Godavari
b) Naharkatiya
c) Cambay
d) Gulf of Kutch
Explanation: Oil deposits are obtained from the exploration of the Godavari delta. The production of petroleum high is still in progress. Also in the Gulf of Kutch there is still exploration going on.
7. In which region of Uttar Pradesh oil refinery is located?
a) Lucknow
b) Mathura
c) Agra
d) Lalganj
Explanation: Mathura oil refinery is the sixth refinery founded by the India Oil Corporation Limited. This refinery was founded for meeting the demands of petroleum products in the north-western region of the country
8. Which of the following method is used for the detection of deposits of oil by mapping the age of rock?
a) Visual method
b) Seismic method
c) Drilling
d) Geological method
Explanation: As the name suggests, this method comprises of mapping the age of rocks, their nature and the types of formation present. These are sometimes assisted by aerial photography.
9. Which of the following is a geophysical method for the detection of oil deposits?
a) Gravimetric method
b) Geological method
c) Visual method
d) Drilling
Explanation: Gravimetric method is the method in which the variations in density of the earth’s crust are measured with sensitive instruments. There are more two types of geophysical method which includes a seismic method and magnetic method
10. For what purpose does the cores for drill are examined?
a) For the fossil fuels occurring in strata
b) For mapping the age of rocks
c) For fossil formation and evidence of non-porous rocks
d) For checking the intensities of earth’s magnetic field
Explanation: Drilling provides the final proof for the occurrence of oil-bearing strata. When the existence of oil deposit is proved, drilling is continued until the depth of the oil or oil-bearing strata is confirmed.
