petroleum was not properly discovered in that time and no major role did it played.


before the 1900s petroleum did not play a significant role as it does now. the petroleum discovered at that time was mainly by oil seepages. The anticlinal theory was not known. during 1900 to 1920 petroleum was widely discovered in many countries. the main use of petroleum started after world war 2
