The widely used conventional sources of energy in Oman In 1925, Oman discovered the largest revenue base in the Sultanate. That is, basic energy standards. The standard or non-renewable energy base is the energy base that has been industrialized millions of years ago and cannot be renewed or replaced with a new one comparable in the location of the one used (omaninfo.com, 2002). Oman is also considerably dependent on two main sources of energy, oil and gas. They are said to account for 70 to 80 percent of employees from standard power sources in Oman. Furthermore, they are believed to account for 40% of Oman's gross domestic product(). The three fossil fuels in the form of coal, oil and gas are the most important and reliable human sources of energy production so far. They make up about 92% of total energy production sources, while other sources only account for about 8% (EnergyKids, 2013). Black gold (oil) Oman discovered oil, decades after most Arab states and it was no bargain. numbers until 1962. In fact there have been countless factors that have contributed to stopping the invention of oil fields such as; the fields were smaller, more extensively dispersed, less productive, and more expensive per barrel than traditional fields due to the harsh topography of the terrain. Furthermore, Oman has resorted to current methods or EOR (enhanced oil recovery) methods to reduce the price of oil discovery and to discover new oil fields that contain more oil. (omaninfo.com, 2002). About 5.5 billion barrels of oil reserves in Oman are located in the northern and central regions. They are located in the north at Yibal, Natih, Fahud, al-Huwaisah and Lekhwair which produce almost half of the finishing......half of the paper......all the gas creation in the last countless years has taken place in the development of traditional gas-based industries, such as petrochemicals, manufacturing manipulation, and the use of natural gas as a feedstock for improved oil recovery projects. The Sultanate of Oman has discovered that the largest liquefied gas land 450 km from Muscat exceeds its size. Kausar, who described it as the largest gas land discovered in the last six years. And that the new land is placed at a depth of 40,500 meters in the land adjacent to the huge Sih Roll land in central Oman. It is the deepest land among the previous gas fields that has been discovered previously. (GECF, 2013). Ultimately, these are the energy sources currently available in Oman, and they are the most useful, due to their great power in electricity production and their importance in modern industries.
