I`m a high school student please i wish to ask what are the subjects needed to study petroleum geologist.
Most programs at universities require the following:
Basic Chemistry 1 year (1 year is two semesters)
Mathmatics up through Calculus,that includes algebra, trigonometry, and calculus. This is usually three or four semesters
Physics 2 semesters
Physical Geology and historical geology 2 semesters
Paleontology 1 semester
Sedimetology and sedimentry petrology 2 semesters
Mineralogy and Petrology 2 semesters
Then you can take a number of electives in areas of interest to you that would be useful such as:
Well log interpretation
Flow through Porous medium (Hydraulics)
Computer science especially any class that exposes you to using geology and geophysical software.
So in highs school take chemistry, algebra trig and calculus and physics if you can.
