Liquid fuel engineers evaluate liquid fuel extraction sites. They design and develop methods for extracting liquid fuels from underneath the earth surface, these fuels include petroleums, natural gas, liquefied petroleum gas, non-petroleum fossil fuels, biodiesel and alcohols. They maximise the recovery of hydrocarbon at a minimum cost, pursuing minimal impact on the environment.

Tasks

Tasks include -
(a) Determining the location and planning the extraction of coal, metallic ores, non-metallic minerals, and building materials, such as stone and gravel;
(b) Determining most suitable methods of efficient mining and extraction and types of machinery to be used, planning layout and directing construction of shafts and tunnels;
(c) Determining drilling site and devising methods of controlling the flow of water, oil or gas from wells;
(d) Planning and directing storage, initial treatment and transportation of water, oil or gas;
(e) Establishing safety standards and procedures and first-aid facilities, especially underground;
(f) Conducting research, developing methods of extracting metals from their ores and advising on their application;
(g) Investigating properties of metals and alloys, developing new alloys and advising on and supervising technical aspects of metal and alloy manufacture and processing;
(h) Maintaining technical liaison and consultancy with other relevant specialists such as geologists and geophysicists;
(i) Examining deposits or mines to evaluate profitability.
