Gas and oil deposits are typically found inside sedimentary rocks because of decomposing plants and animals trapped in layers of rocks. These rocks being usually consisting of clay pieces, sand, and mud. These rocks are layered and deposited on sediment layers. The remains of small organic materials such as zooplankton and algae form petroleum. Vast quantities of these remains settled to sea or lake bottoms, mixing with sediments and being buried under anoxic conditions. The heat and pressure over millions of years have turned the mud to rock and the organic materials to petroleum. The formation of petroleum occurs in two steps. The first step is Diagenesis, the second step is Catagenesis.
Diagenesis is the process of compaction on the low pressure and temperature conditions. This process includes any chemical, physical, and biological changes in sediments after the initial formation. However, the result of weathering and metamorphism is not considered. The organic materials contain proteins, lipids, and carbohydrates and they are rich in water. When they are deposited, as a result of chemical reaction, microbial action, and compaction the water is forced out and the proteins and carbohydrates are broken down to form waxy substances called “kerogen” and “bitumen”. Catagenesis is thermal degradation of kerogen due to increase in temperature in deeper burials. Catagenesis or cracking will turn the kerogen to hydrocarbon chains. Gas and oil is found underground trapped inside
For our science assessment we had the task to research about a metal of our choice. Since I am really into computers, I chose copper. A metal used in all kinds of wires, cpu’s and other stuff without a computer wouldn’t work. This fits really well into what we have to do for the second part, describe how this metal has helped human society.
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
The most important of these is the Permian Basin. In the latter half of the Paleozoic era, sediments rich in organic matter accumulated here when a shallow sea got cut off from the main oceans and evaporated off, leaving lots of dead critters and evaporites. These sediments eventually got buried and compressed, causing the oil and gas to form "pockets in permeable rock, surrounded by impermeable rocks so that they couldn't escape. There the fluid sits until someone pokes a hole (well) into the area and the contents rush out as the tremendous pressure is released. Other areas of Texas with notable petroleum sources include East Texas's Woodbine Formation (formed in the Late Cretaceous), much of the Gulf Coast and the Gulf itself, and various smaller pockets in South and South Central Texas.
Petroleum is created over millions of years from dead alagae that goes to the bottom of the ocean and is buried beneath the surface.
The Copper Basin of southeastern Tennessee is an area that is climatically unique with a rich history rooted in copper mining. It is thought that man is responsible for the total destruction of the environment over this large area, but it is mostly contributed to the exclusive location. The Copper Basin was susceptible to negative environmental effects due to its topographical, geological, climatic, edaphic, and meteorological location. However, the copper mining had a transformative effect on the surrounding lands that of which are still recovering.
Diatomite is a rock that forms from the silica cell walls of a group of unicellular algae known as diatoms. Diatoms are found in both fresh water and salt water. When they die, their cell walls dissolve under water and become compacted over time into diatomite. The fossilization rock, may have fossil remains of many kinds of plants preserved within it. Amber is considered a mineral that is used as a gem but is less valuable than precious stones. Amber or semiprecious stones is the fossilized resin produced by earlier cone-bearing evergreen trees. Before resins harden, floral parts, pollen grains, fungal spores, and other plant parts may become trapped and be preserved. Amber is valued for jewelry and as fossils mainly from two parts of the world, the region of northern Europe and the Dominican Republic. When describing different types of fossilization, specific qualities of the fossil are used. A two-dimensional with organic material is called compressions. The physical 3-D structure is compressed to one or two-dimensions. Peat, lignite, and coal are compressions of thick plant debris of covered mineral sediment. Impressions are two-dimensional imprints lacking organic material. If the sediment is grained, impressions may show detailed external forms of the plant. Casts and models is a three-dimensional that has a surface layer of organic material. A cast is made when sediment is deposited into cavities left by the decay of plant parts. A mold is a cavity left in the sediment by the decayed plant tissue. Molds are usually unfilled, or partly filled with sediment. Casts and molds may be found together with the cast filling the mold. Permineralizations are also three-dimensional with plant tissue being infiltrated by mineral-rich fluid. The internal structure of the plant is preserved in three dimensions. Lastly, molecular fossils are non-structural and preserves organic
During the Eocene epoch, 47,000,000 years ago, one of our ancestors lived in what is now Germany. She was still young, her baby teeth still intact and probably less than a year old. This little girl came to a lake’s edge for a drink of water; cupping the water with her hand she slowly drank the water while holding onto a branch with her other hand. Our ancestor died there when she was overcome by an underground gas bubble that erupted, the fumes leaving her unconscious; she fell into the water and drowned. Her body slowly drifted to the bottom of the lake with a myriad of other creatures. The lake where she was buried eventually filled with mud and algae that turned into oily shale
The formation is located in western North Dakota, southern Saskatchewan, northeastern Montana, and southwestern Manitoba, and has a depth of approximately 130 feet to 12,000 feet deep. The upper and lower Bakken shale layers contain large amounts of organic-rich black mudstone. During the Lower Bakken Member deposition, an increase in the rate of siliciclastic sedimentation (quartz and orthoclase feldspar) caused more organic material to be preserved in bottom sediments. During Upper Bakken Member deposition, an increase in biological productivity in the water column resulted in more organic carbon reaching the bottom where it was subsequently preserved (Bustin & Smith, 1995). The middle layer is made up of mostly mudstone and sandstone. This layer can be tapped by both conventional and continuous oil
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
This document describes in detail the organic petrology and maturation of the Bakken Formation located in the Williston Basin. This report is organized into five sections. Section I will introduce the Bakken Formation in reference with the Williston Basin. It will also address sedimentary and structural aspects of the Bakken Formation. Section II outlines the processes that formed the Bakken Formation that occurred during the Devonian/Mississippian age. Section III will summarize organic components and influence within the Bakken Formation. Furthermore Section IV will address the nature of inorganic constinuents that influence the Bakken Formation. Section V will discuss production history and current production of oil and gas found within
The purpose of this paper is to explain the depositional environment, petrology, mineralogy, structure, exploration, technology, methods of extraction and processing, as well as the applications and economics of oil in the Greater Green River Basin. This paper will mainly focus on the oil shale within the basin but will also touch on some of the more conventional oil and gas plays as well. According to Crawford and Killen (2010), Oil Shale is defined as being “a sedimentary rock embedded with organic material called kerogen… and has not been under the necessary heat, pressure, and/or depth for the right length of time to form crude oil”. Oil shale is typically found in silica and carbonate based rocks that are usually no greater than 900

The formation of the other two fossil fuels (crude oil and natural gas) took millions of years just like coal. Oil and gas come from the remains of small animals and plants. Long ago, when the animals and plants died, they sank to the bottom of the sea. The dead matter formed a large mass, which over time was covered by layers of sand, silt, and mud. As the weight of the sediment increased, the mass became more and more compressed. Then, the heat and pressure of the Earth eventually turned the mass into oil and gas. If the heat applied during the formation was low, then more oil was produced than gas. If the temperature was
Coal, oil, and gas were all formed from the remains of decayed and decomposing ancient animals and plants (Science Daily 2014). These fossil fuels we produced far before the dinosaurs ever roamed the earth, during the Carboniferous Period (Chapter 8 2012). This period of time, estimated around 360-286 million-years-ago, is believed to be when the earth was covered mostly in trees, plants, and swamps, and the bodies of water existing at the time were all filled with hundreds-of-millions of small plants called algae.
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
