The Institute of Oil and Gas, an institution of higher technical education unique in Romania, was founded in Bucharest in 1948 (according to Decree no. 175/1948 for the education reform, published in the Official Gazette no. 249 / 26.10.1948) and consisted of two faculties: the Faculty of Drilling-Production (currently - Faculty of Petroleum and Gas Engineering) and the Faculty of Crude Oil Processing (currently, the Faculty of Petroleum Technology and Petrochemistry). In the period 1950-1957, the two faculties were joined by the Faculty of Petroleum Machinery and Equipment (currently the Faculty of Mechanical and Electrical Engineering), the Faculty of Economics and Organization of the Petroleum Industry (it was established in 1950 and operated until 1958) and the Faculty of Technical Geology (established in 1950 under the name of the Faculty of Geology of Oil and Gas Deposits and expanded after the transfer in 1957 of the Faculty of Geology from the Institute of Geology and Mining Technology in Bucharest). In 1973, by Decree no. 702 / 28.12.1973 at the State Council it is provided that the Ploiești Petroleum Institute is unified with I.P.G.G. Bucharest under the name of the Ploiești Oil and Gas Institute (I.P.G. Ploiești).

The name University of Ploieşti became official by Order of the Ministry of Education and Science no. 5590 / 6.07.1992, and then the “Oil - Gas” University of Ploieşti (name became official by the Romanian Government Decision no. 458/1994) and finally the Oil - Gas University of Ploieşti (name became official by the Romanian Government Decision no. 23 of 11.01.2001).

We can consider the academic year 1950-1951, the year of establishment of mechanical engineering education, so the year of establishment of the Faculty of Petroleum Machinery and Equipment is 1951. The Faculty of Petroleum Machinery and Equipment was the first faculty to move to Ploiești. It started it's activity in the academic year 1967 -1968 with the first year of the Faculty of Petroleum Machinery and Equipment. According to HCM no. 2364 of 1967, by which the Faculty of Petroleum Machinery and Equipment was moved to Ploiești, the students enrolled at IPGG Bucharest continued their studies until graduation in Bucharest, and the students enrolled in the academic year 1967-1968 started their studies in Ploiești , within the newly established Petroleum Institute.

Since its establishment, the EMI faculty has changed its name several times:

-between 1952 and 1975 - Faculty of Petroleum Machinery and Equipment (MUP);

-between 1975 and 1986 - Faculty of Technological Equipment (UT);

-between 1986 and 1990 - Faculty of Petroleum Equipment and Technology (UTP);

-since 1990 and now - Faculty of Mechanical and Electrical Engineering (EMI).
