Oil & Gas Production & Refining Operations

About this Program


This program teaches how oil and gas are explored, drilled, produced and processed. It describes how well flow, a mixture of oil, gas, water, sand etc., is separated and processed into ‘clean’ marketable crude oil and gas products, using various separator vessels.


Separators are vessels in which mixtures of insoluble fluids, are separated from each other. They are used most often in oilfields, than any other process equipment in process facilities. In addition participants will be taught the oil and gas production process. Associated facilities and equipment like pumps, valves, desalters, towers and columns, pipeline and piping, as well as fractionating column and industrial water processing facilities are equally treated.


Petroleum oil refinery is an industrial process plant where crude oil is transformed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils. Oil refineries are typically large, sprawling industrial complexes with extensive piping running throughout, carrying streams of fluids between large chemical processing units, such as distillation columns.


The crude oil feedstock has typically been processed by an oil production plant. This will form a major part of this program. There is usually an oil depot at or near an oil refinery for the storage of incoming crude oil feedstock as well as bulk liquid products. An oil refinery is considered an essential part of the downstream side of the petroleum industry.
Some modern petroleum refineries process as much as 800,000 to 900,000 barrels (127,000 to 143,000 cubic meters) per day of crude oil.


According to the Oil and Gas Journal in the world a total of 636 refineries were operated on the 31 December 2014 for a total capacity of 87.75 million barrels (13,951,000 m3). Nigeria has three government-operated refineries. The largest one in Africa, is said to be coming on-stream soon, in Lagos. In the core Niger Delta, many “illegal” refining operations, featuring “crude and polluting”, but “usable” refined petroleum products are going.
The core of this program features the oil and gas, exploration, drilling, production, separation and general processing of ‘clean marketable’ crude oil and gas.
