Petroleum technology covers a wide range and the specific tasks of petroleum technologists are dependent on the field in which they work. Petroleum technologists are involved in the search for new oil-wells. This involves geological work and those involved in this field are known as geological petroleum technologists. In the extraction process the petroleum technologists do research on the different types of mud used to lubricate drill bits.
Petroleum technologists are also involved in the evaluation of crude oil to determine its specific properties and classification which will, in turn, determine the refining parameters. Testing and evaluation of the various cuts are done by laboratory petroleum technologists during the refining process.
Petroleum technologists are employed by Chemical Industries, in the refineries of various oil companies and other manufacturing industries, as well as in marketing sections. Employment can also be found in the re-refining.
There are currently no known opportunities for self-employment in this career.
