Enhanced Oil Recovery
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 efforts are made to increase the quantity of oil that can be extracted again from the oil well and we refer to these efforts as “recovery”. There are three main types of recovery, primary recovery (solution gas, gas cap and natural water drive) secondary recovery (gas injection and water flooding) and tertiary recovery (enhanced oil recovery EOR, polymer flooding and steam flooding). In this article, analysis on the “enhanced oil recovery” technology and trends will be emphasized upon.

ENHANCED OIL RECOVERY

Enhanced oil recovery becomes very vital when oil production has to be increased to obtain a recovery percentage of at least 75% (Rigzone, 2009). This can only achieved by using any of the four basic methods of EOR; these methods include chemical flooding, miscible gas displacement, thermal recovery and microbial EOR. Among these four mentioned, “Thermal methods are the oldest EOR methods, they have been developed over the last thirty years” (Elsevier, 1981). Miscible gas displacement also called “gas injection” by some engineers refers to the process of injecting CO2, natural gas and Nitrogen into a reservoir; “in miscible gas displacement, the gas is injected at or above the minimum miscibility pressure (MMP) which

    Today, with the continual and rapidly growing need of energy demand by big nations like United States and China continuing to furnish their domestic consumptions of oil have led to increased prices of gasoline whereby alternative forms of energy production are sought. With this in mind, offshore drilling can be a viable option for satiating the need of oil and also to boost the economy of the nation. In this report, I am going to discuss how the current Deepwater Horizon rig explosion has led to disastrous oil spill into the Gulf of Mexico causing environmental problems and also discuss how the oil spill if resolved and with safe and secure drilling techniques, the economic impact of offshore drilling can outweigh the environmental issues.…

    Oil is a natural resource that comes from beneath the earth’s crust; it is trapped in pockets under the earth. Finding oil trapped underground is very complicated and costly, it takes millions of dollars to drill a well and only a few are successful. Oil travels upwards from the rock in which the oil is formed, when the oil meets a cap rock (a rock with no spaces in-between the grains) is it trapped. Soon after when oil pockets are found, a well is drilled so that the oil can travel up to the well and be retrieved. After the oil is retrieved it must be separated as the oil is a mixture of water, crude oil and gas and to transport the oil safely you must first separate all the different elements/compounds. After all of this the oil is safely transported to and from countries, across seas, wherever the oil is needed.…

    Offshore Oil Drilling

    What do we do to obtain oil to meet the needs of Americans without having to “sell out” to Middle Eastern countries, not only with money but with foreign policy? This paper intends to refute the claims of those opposing America’s attempts to address its own energy needs rather than rely on the oil sources of other countries. In many of his campaign speeches President Obama stated that we need to become less dependent on foreign oil and at the same time less dependent on oil all together. Many Americans would also agree with this. It has been known for years that everything is a “give and take” and that you can’t please everyone. Though none of these changes can occur over night, it is absolutely imperative that the changes do happen now or we will continue on our downward spiral of becoming more and more dependent on foreign oil production.…

    What is Hydraulic Fracturing: Hydraulic fracturing or “fracking” is a well stimulation process used to maximize the extraction of underground resources including oil and natural gas. Hydraulic fracturing involves the pressurized injection of a mixture of water, chemicals, and sand in underground formations to allow natural gas and oil to flow more freely from rock pores to the surface. (Watershed Council p.1) A modification of this technique, called slickwater fracking, was used in Texas in 1998 to drill for natural gas from the Barnett Shale. Massive hydraulic fracturing treatments have been done in German tight sandstone gas wells since 1975. In 2012, the first research has begun in North Jutland where 80% of underground gas has been commissioned for extraction by Total E&P Denmark B.V., a subsidy of the multinational company Total S.A.. “ In the southern portion of South America, Argentina’s Neuquén basin appears the most prospective with good potential evident in the Cretaceous…

    Edward Burtynsky was born in 1955 in St. Catharine’s, Ontario, and a graduate from Ryerson University holding a Bachelor of Applied Arts and studied Graphic Art at Niagara College in Welland. His photographic art interests stem from the sites and images of the General Motors plant in his hometown and he inspiration holds a link between industry and nature. Edward Burtynsky states “nature transformed through industry is a predominant theme in my work. I set course to interact with a contemporary view of the great ages of man…To make these ideas visible I search for subjects that are rich in detail and scale yet open in their meaning.” Burtynsky is an artist who looks to photograph the dilemma of our society and depict the metaphors (Burtynsky). Travelling across the world, taking photos and exhibiting them is not the only thing that Burtynsky does. He hosts public lectures about his work and has written a book and has completed film projects (Laurence). His works under his collection “Oil” fit what he looks as “nature transformed through industry” perfectly. He chooses to photograph his oil and its effects in series of a map form, starting with the extraction and then how we use it, in cities and cars, and gathering around vehicles to celebrate. Finally the idea of the end of oil, where our parts of cars, and helicopters end up, where all the things made and that use oil end up (TED). Burtynsky’s series on oil informs the viewer and leaves the viewer questioning.…
