INTRODUCTION
Oil and Gas refers to the naturally occurring liquid and natural gas specifically made up of long chain hydrocarbons and various organic compounds found beneath the surface of the earth in entrapments called reservoirs; the presence of oil and gas in these reservoirs is the reason humans survive everyday and carry out their daily activities effectively. Different activities are usually carried out to ensure that the oil and gas present in the reservoirs continue to support humans through their day-to-day activities; such activities include exploration, development, production and finally, abandonment and reclamation. This process is what is referred to as “the oil and gas process”. On completion of this process, numerous

The minimum miscibility pressure of nitrogen depends largely on the pressure, temperate and the composition of the reservoir fluid. According to Schlumberger, “above the MMP, nitrogen injection is a miscible vaporizing drive. Miscibility of nitrogen can be achieved only with light oils that are at high pressures; therefore, the miscible method is suitable only in deep reservoirs” (2011). Both methods of miscible injection from past experiences have proved very effective. When oil has been effectively recovered from these reservoirs using the miscible gas, the gas that has mixed with the recovered oil is separated from the oil and re-injected into the reservoir to enhance the oil recovery once again. This process can be repeated until the reservoir is completely depleted and cannot produce any more oil. Note that nitrogen gas injection is used when dealing with reservoir containing light oils and also very economical allowing a recovery of up to 40%. A practical example of nitrogen gas injection is in the Cantarell oil field in Mexico. Upon application of this enhanced oil recovery methods, there was a noticeable increase in the oil production from 1.9 million bpd to 2.1 million bpd.

When a new oil field begins its production process, nature takes its course and does most of the work. The natural pressures from the reservoir force the oil into production
If you own a vehicle, you probably know that you need to get your oil changed. but do you know whey you need to get your oil changed? Here are some answers to your top questions about this necessary vehicle maintenance.
When people hear the word oil it is commonly interpreted as gas, but the oil that we drill is not what goes into our cars. The oil that is retrieved from the ground is called crude oil, Oil in its raw natural form and when it becomes refined it is used in plastics, rubber, and gasoline. ”Gasoline is a volatile, flammable liquid obtained from the refinement of petroleum, or crude oil. It was originally discarded as a byproduct of kerosene production.” The first oil well was found and harvested in Titusville, Pennsylvania by a man named Edwin L. Drake, in 1859. The well was about 70 feet deep (How gas). It pumped between 20-40 barrels a day
Gas and oil is usually formed over thousands and thousands of years under large bodies of water, where organic materials have died. The organic material of plants and animals settle to the bottom of the waters floor and
The GC-MS and the UV-Vis instruments were used to determine the relative purity of the provided pure olive oil and extra virgin oil samples along with an unknown mixture of oils. The given oil samples were processed through a transesterification method to yield methyl esters that were smaller in molecular size and more volatile to be processed through the GC-MS using a method derived from a known procedure.[2] The data derived from the GC-MS was used to identify the original acids based on the methyl esters identified and the relative concentration of individual components. The pure olive oil followed the literature components and values with a slight deviation in concentration and the impurity of lauric acid, typically found in other vegetable-based oils.[6]
It has come to conclusion that fossil fuels are organic materials that are buried in combustible geologic deposits of organic materials. These fossil fuels are formed from decayed organic materials, animals and rocks that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the Earth's crust for a very long time. Changing the use of energy can cause effects such as; economic issues and environmental issues. Although, energy is in need of production, many
A petroleum system is a system that includes a pod of some active source rock with their very nature genetically related to build up and accumulation of oil and gas. Petroleum system includes geological elements, as well as the processes, which are crucial and essential for the existence of oil and gas accumulation. Petroleum is a compound that is made up of high concentrations of biological and thermal hydrocarbon gaseous components that are contained in conventional reservoirs, tight reservoirs, fractured shale, gas hydrates, as well as coal. It also includes high concentrations of condensates, crude oils, and natural bitumen in the reservoirs, and generally in carbonate and siliciclastic rocks. In this view, we may describe a system as an interdependence of elements as well as processes, which form the very functional unit that gives rise to the hydrocarbon accumulations (Mancini, Parcell, Puckett, & Benson, 2003).
Unconventional in terms of oil and gas simply means low permeability rock where the pores are poorly linked thereby making it difficult for oil and gas to move through the rock. The development of unconventional reservoirs provides new challenges that might be overcome with new techniques and approaches This has radically changed perceptions of gas supply availability in the US and elsewhere by originating a revolution in the global gas markets.
The oil industry can not be discussed without mentioning the name John D. Rockefeller. Rockefeller changed the business of oil distribution. In the 19th century Rockefeller began his humble beginnings with a small investment, along with two other partners, in the oil refining business. Eventually Rockefeller upset at the direction of the company bought out his partners. He was now buying into refining and developing kerosene and other petroleum-based products. He later named this company The Standard Oil Company which by 1872 nearly owned all the oil refineries in Cleveland. In 1882, Rockefeller took all his holdings and merged them into the Standard Oil Trust. Through smart business

The oil and gas industries involve a high amount of documentation for both transportation as well as extraction and field services. Activities are highly regulated, and subject to oversight from Federal Energy Regulatory Commission (FERC), the Department of Transportation (DoT), the Environmental Protection Agency (EPA), and the Department of the Interior (DoI). That said, the process of regulation is trending toward a more digitized system, with organizations like FERC having their own submission portals that implement a “fill-in-the-blank” platform to complete forms. However, not all forms have yet been converted to digital submission even in agencies with online portals, and other agencies still remain reliant on
Cars are important for everyday life and allow citizens to function normally in society. Whether it is a personal car, Uber, or rental, cars wear and tear daily and need repairs often.
Most people now believe that oil and gas are formed when the remains of dead animals and plants are mixed with sediments, buried and formed into rocks and then heated deep underground. The oil and gas then seep out through porous rocks where they may or may not collect in an oil or gas field.
Currently Saudi Arabia is one of the leading producers of oil in the world. However, it is losing its foothold on the market. Many countries, like North America, are increasing their oil production and are looking for ways to become less dependent on foreign oil. The increased competition has caused oil prices to decrease. By producing their own oil, countries not only will increase their revenues, but will also reduce their need to rely on foreign oil. By reducing their need foreign an oil a country does not have to worry that their oil supply will be cut off if they go to war.
Since the past few decades, owning a car has become a necessity in order to commute from one place to another. However, cars do not work automatically, they require fuel. Since the past decade, the petroleum industry has become one of the leading industries impacting the nation’s economy. Oil has become an essential commodity as it is utilized in transportation vehicles, serves as a raw material for manufacturing plastics, and is utilized in homes for cooking. America’s economy is greatly dependent on petroleum as it is the “black gold” of the nation. The considerable significance of oil has led to the drilling of it, which is not only limited to land, but also the oceans. Offshore drilling is a method in which petroleum is extracted from underneath the seabed. It is one of the significant technological advancements in the past few decades. However, the ones who are involved in the process of offshore oil production are humans, and humans tend to make mistakes. In 1969, due to a human error, an oil spill occurred and natural gas, oil, and mud shot up the well and oozed into the ocean (“Offshore Drilling”). The oil spilled led to an environmental disaster which killed thousands of marine animals and distorted the environment. In order to prevent the same error, the government passed a moratorium in 1981, banning more than 85 percent of the country’s oil drilling sites (“Offshore Drilling”). The moratorium restricted the United States to mass-produce its natural resource.
