Exploration about economic Minerals in earth's crust such as Gold (Au), Silver (Ag), Copper (Cu), Nickel (Ni), Cobalt (Co), and REE.Typical duties include:- Investigating the structure and evolution of the earth and its natural resources.- Planning programmes for exploration of sites for oil, gas, water, minerals, etc.- Surveying and mapping geologically promising sites.- Collecting, recording and analysing samples and data from test sites.- Advising on the development of reserves.

working in wellsite units collecting, processing, logging and analysing geological samples;using various laboratory techniques to evaluate detailed and complex data for signs of oil or gas;monitoring computer recordings of drillings; interpreting information and feeding it back to the drilling team to enhance safety and success; operating and maintaining a real-time computer-based data acquisition system, the advanced logging system (ALS), which records all aspects of rig activity; undertaking some on-site maintenance, for which a knowledge of electrical and mechanical systems is useful; taking on the primary health and safety role for the well through constant monitoring of all critical drilling parameters; predicting dangerous situations, such as over-pressured formations; assisting the wellsite geologist during coring operations; reporting to the wellsite geologist and the oil company in written reports; frequently acting as a drilling engineer, collating and then logging details of drilling operations in oil companies' computer systems.
