On 20 April 2010, the semi-submersible exploratory offshore drilling rig Deepwater Horizon exploded after a blowout; it sank two days later, killing 11 people. This blowout in the Macondo Prospect field in the Gulf of Mexico resulted in a partially capped oil well one mile below the surface of the water. Experts estimate the gusher to be flowing at 35,000 to 60,000 barrels per day (5,600 to 9,500 m3/d) of oil.

Introduction:
Oil spills are a serious problem all over the world. It is widely known that oil is the very important resources in human daily life. In this research paper, I will discuss how government and environment scientists have to solve this situation. Billions of dollars are lost and it is an oil spill disaster management so as to rehabilitate the environment. Many countries are focusing on finding a safer ways to transfer oil between countries and remedy the spills. As a worldwide problem, the public should pay more attention to the consequence of oil spills, to prevent the advance effects and seek a preventative measure of the long-term effects associated with oil spills.
Thesis statement: Oil spills cause both short-term and long-term environmental destruction, some of the effects of oil spills can be long-lasting. This research paper looks into the cause and effects of Oil Spills
Cause and Effect Pattern, Problem
Oil spills in water bodies such as rivers, lakes bays and ocean or along the pipelines are usually as a result of accidents which may involve oil tankers, breakage or linkages on the pipeline storage facilities or accidents on the drilling rigs. More often than not these spills are caused by human errors or negligence during operations sometimes equipment's may break down resulting in oil spillage. Another cause of oil spillage is natural disasters such as hurricanes and earthquakes. When they occur they result in massive destruction of the oil storage and drilling facilities. More often than not, a majority of oil transportation facility does not withstand the impact of earthquakes hence they break down causing spillage. In recent years there have been reported spillages caused by deliberate acts e.g. by terrorism, war and vandalism. Illegal dumping of used engine oil and grease has also emerged as a major cause of oil spills.
Oil spills have two major categories of effects namely economic and environmental effects the effects are similar for both patterns only that the large spills have a far-reaching effect. To begin with, we shall look at the environmental effects. Oil spill covers the shoreline with oil residue, as a result, it becomes difficult for plants to thrive. When it occurs on the land, it covers plants, therefore, hindering transpiration as a result plants wither off and die. Aquatic animals choked to death. When the pattern is large the young once of wildlife animals may starve to death because the oil covers there skin making it hard for the mothers to detect their natural smell. Marine oil spills destroy plankton and collar reefs (Ramseur, 2015).
Heavily furred sea mammals subjected to oil spills are afflicted in similar ways. Oil coats the hair of sea otters and seals, lowering its insula ...
Deep Water Horizon Accident - by ALOKRANJAN.ORG.INALOK RANJAN
The Deepwater Horizon accident, also known as the BP oil spill or the Macondo blowout, was a catastrophic event that occurred on April 20, 2010, in the Gulf of Mexico. It was one of the largest marine oil spills in history and had severe environmental, economic, and social impacts.
Here are some key details about the Deepwater Horizon accident:
1. **Location and Context**: The Deepwater Horizon drilling rig was located approximately 40 miles southeast of the Louisiana coast in the Macondo Prospect, an oil field estimated to hold significant oil reserves.
2. **Cause of the Accident**: The disaster was triggered by a blowout—a sudden and uncontrollable release of oil and gas—from the Macondo well. This blowout led to a series of explosions on the drilling rig.
3. **Explosion and Sinking**: On April 20, 2010, a surge of methane gas from the well caused an explosion on the Deepwater Horizon rig. The explosion and subsequent fire resulted in the deaths of 11 workers and injured 17 others. The rig eventually sank on April 22, 2010.
4. **Oil Spill**: The blowout caused a massive oil spill that continued for 87 days until the well was successfully capped on July 15, 2010. It's estimated that approximately 4.9 million barrels (210 million gallons) of oil were discharged into the Gulf of Mexico.
5. **Environmental Impact**: The spill had devastating effects on marine and coastal ecosystems. It harmed fish, birds, marine mammals, and other wildlife. The oil also damaged wetlands, beaches, and estuaries along the Gulf Coast, impacting tourism and fishing industries.
6. **Response Efforts**: The response to the spill involved a massive cleanup operation by BP (the owner of the well), government agencies, and volunteers. Various methods were used to contain and remove the oil, including controlled burns, chemical dispersants, and the deployment of booms.
7. **Legal and Financial Consequences**: BP faced extensive legal action and paid billions of dollars in fines and settlements for environmental damage, economic losses, and cleanup costs. The spill also led to changes in offshore drilling regulations and safety standards.
8. **Long-term Effects**: The environmental impact of the Deepwater Horizon spill continues to be studied. Scientists are monitoring the recovery of affected ecosystems and assessing the long-term effects on marine life and habitats.
The Deepwater Horizon accident highlighted the risks associated with offshore oil drilling and emphasized the importance of stringent safety measures to prevent similar disasters in the future.

On 20 April 2010, the Deepwater Horizon explosion, which released a US government-estimated 4.9 million barrels of crude oil into the Gulf of
Mexico, was responsible for the death of 11 oil workers and, possibly, for an environmental disaster unparalleled in US history. For 87 consecutive
days, the Macondo well continuously released crude oil into the Gulf of Mexico. Many kilometers of shoreline in the northern Gulf of Mexico were
affected, including the fragile and ecologically important wetlands of Louisiana's Mississippi River Delta ecosystem. These wetlands are responsible
for a third of the nation's fish production and, ironically, help to protect an energy infrastructure that provides a third of the nation's oil and gas
supply. Here, we provide a basic overview of the chemistry and biology of oil spills in coastal wetlands and an assessment of the potential and
realized effects on the ecological condition of the Mississippi River Delta and its associated flora and fauna.

The uncontrolled blowout of the Macondo wellhead, locatedat Mississippi Canyon Block 252, which occurred on
20 April 2010 during the completion of drilling by the
Deepwater Horizon (DWH) drilling platform, is potentially
one of the largest environmental disasters ever experienced
in the United States, and, without question, the largest
marine oil discharge. The release of a US government-
estimated 4.9 million barrels of oil exposed the nation's
largest and most productive wetland-estuarine environ-
ment to an unprecedented level of environmental impact
(National Commission on the BP Deepwater Horizon Oil
Spill and Offshore Drilling 2011). The coastal wetlands of
the Mississippi River Delta ecosystem, which constitute
almost 40% of the coastal wetlands of the 48 conterminous
United States, is of special concern because of the multitude
of environmentally and economically important services
that they supply to the northern Gulf of Mexico (GOM) and
to the entire United States. These wetlands provide the base
for such ecosystem services as storm protection, water qual-
ity enhancement, faunal support, and carbon sequestration.
Approximately 30% of the United States' commercial fishery
production is dependent on these wetlands, and ironically,
they protect an oil and gas infrastructure that provides
one-third of the nation's oil and gas supply and 50% of the
nation's refining capacity.
Of course, the DWH spill is not the first to affect coastal
wetlands. In the United States alone, multiple smaller
spills occur each year. However, large spills that resul ...

A brief study on synthesis of surfactants and the mechanism of oil mobilizationIOSR Journals
Surfactants finds application in almost every industry of which the detergents, paints, dye-stuffs cosmetics, pharmaceuticals, pesticides, plastics, food, agriculture, asphalt, fuel etc are worth mentioning. Moreover surfactants play a vital role in the oil industry. An important and interesting aspect of the chemistry of surfactants which has not been systematically investigated hitherto, in the utilization of so prepared surfactants as emulsifiers with special reference to the study of interfacial tension, surface tension, viscosity, particle size and conductance and their use in the field of enhanced oil recovery .Oil\Water emulsions have been prepared by taking two immiscible liquids as internal and external phases using surface active agents. The present paper deals with the studies on the synthesis of surfactants. Three surfactants viz- RL-1, RL-2 and RL-3 have been synthesized by using cetyl palmate, acyl alcohol, vinyl acetate, cetyl behenate, cetyl stearate, benzene and benzoyl peroxide. From the analysis it is found that above prepared surfactants are ester copolymers

Understanding exposure is essential to understanding whether the toxic properties of chemicals have been or will be expressed. This presentation provides a view of how the magnitude of exposure comes to be understood.
Water has the chemical formula H2O, making it an inorganic substance. It is the primary chemical component of the Earth's hydrosphere and the fluids of all known living things (in which it serves as a solvent[1]). It is transparent, flavorless, odorless, and almost colorless. In spite of not providing food, energy, or organic micronutrients, it is essential for all known forms of life. Its molecules are made up of two hydrogen atoms joined by covalent bonds and have the chemical formula H2O.
