The Ocean Ranger The Ocean Ranger was an offshore exploration oil drilling platform that sank in Canadian waters 315 kilometres southeast from St. John's Newfoundland, on the Grand Banks of Newfoundland on February 15, 1982, with 84 crewmembers onboard. The Ocean Ranger was the largest semi-submersible, offshore exploration, oil drilling platform of the day. Built in 1976 by Japan's Mitsubishi Heavy Industries, it operated off the coasts of Alaska, New Jersey, Ireland, and in November 1980 moved
Marcellus Shale drilling causes a problem because it involves the use of hundreds of deadly chemicals. Over three hundred chemicals are used in the Marcellus Shale drilling process (Environmental). According to Howells, author of the article “Don’t Frack with Our Water!,” these chemicals are especially dangerous because the companies that use them will not tell the public what specific chemicals are being used. However, through studies of the chemicals, some of them can be identified. Some of the
form of drilling that we have today. Fracking is the use of sand, water, and chemicals injected at high pressures to blast open shale rock and release the trapped gas inside. Still, many debate the use of fracking because while it provides jobs and helps the economy, fracking is awful for the environment because it uses many chemicals in the drilling process and it contaminates large supplies of drinking water. Fracking is a fairly new drilling technique that uses a form of horizontal drilling through
drill offshore. The reason that we drill offshore is because approximately one third of the world's oil resides in offshore fields. (Lynch, 213) There are many ways to drill oil from the ocean floor. The most common way is to construct a steel drilling platform on the ocean floor. Other ways are, first a jack-up rig which is used in waters of up to 200 feet. The rig rests on a floating platform attached to steel legs that can be jacked up or down. It is moved by workers lowering the platform
drawings given by the Consultant. The surveying details for each location should include the reduced levels and coordinates. The place that is surveyed and marked as the pile position shall not be disturbed prior to the commencement of boring works. DRILLING All the associated technical information such as presence of services, pile coordinates, platform and cut-off levels, validity of drawings etc need to be verified by the client's representative to begin the operations. If needed, after setting up
For more than a decade, debate over drilling for oil on the Coastal Plain of the Arctic National Wildlife Refuge [ANWR] has continued unabated. The proposal to drill for oil in Arctic National Wildlife Refuge is heavily urged by the oil companies and supported by most Alaskan government officials, has drawn full scale opposition from powerful private environmental organizations representing millions of members throughout the United States. Congress established the Arctic National Wildlife Refuge
First of all, what in the world is coiled tubing? Otherwise referred to as CT, coiled tubing is a manufactured product used in field operations such as well service, workover applications (petroleum industry well work), and drilling and completion applications. Just as is sounds, CT is essentially a continuous tube with a diameter of .75 inches up to 4.5 inches that is reeled onto a spool, which has a core diameter of approximately eight to twelve feet. The tubing is made from rolling strip metal
sad to see our planet in another few hundred years. We need to start preserving our environment, and not drilling our Great Lakes for oil is a great place to start. If we drill for oil, we will lose much wildlife, destroy habitats, have possible oil spills, and in fact endanger ourselves in the long run. To extract such oil from under the Great Lakes, we would need to use directional drilling. To do this, the well is first drilled vertically, and then it is angled under the lakes at about four thousand
Drilling holes is something most of us have done, whether as part of a hobby, or for our jobs. One of the basic tools for the homeowner, the handyman, or a contractor is an electric drill. While hand-held power drills are some of the most used tools in the box, they are not necessarily the most accurate. When you need an exact hole drilled at a precise angle, or maybe a hundred of these holes, then the tool you want is a Drill Press. The drill press is a larger version of a hand drill with additional
construction workers may be easily exposed to respirable crystalline silica during activities such as the following: · Chipping, hammering, and drilling of rock · Crushing, loading, hauling, and dumping of rock · Abrasive blasting using silica sand as the abrasive · Abrasive blasting of concrete (regardless of abrasive used) · Sawing, hammering, drilling, grinding, and chipping of concrete or masonry · Demolition of concrete and masonry structures · Dry sweeping or pressurized air
The principle of cable-tool drilling has remained unchanged since it first started in China. According to Kurts, DeGolyer (1940) “Drilling is done by repeatedly lifting and dropping a heavy string of drilling tool into the borehole, with the drill bit crushing consolidated rocks into small fragments”. Huge improvements have been made from the Chinese bamboo method. University of Kansas (1940) highlighted the key improvements that the rig mechanisms had. A good example of this is the spring pole
rig operated by Shell E&P, a blowout occurred. This occurred during the upper completion clean up phase of the well. According to the UK parliament’s Memorandum and Transocean’s report, the blowout happened due to an underbalanced column of drilling fluids in the well. This is very similar to the Macondo Blowout, as it also involved an underbalanced column of mud. The only noticeable difference is the use of an unusual spacer and the cementing of the final casing string during the negative pressure
offered to reduce our nation's dependence on foreign countries for oil has been opening up drilling in the Arctic National Wildlife Refuge (ANWR). Proponents say that drilling in ANWR would make the United States more self-sufficient in the area of energy, while at the same time not doing excessive damage to the environment of the area. Opponents of drilling in ANWR cite the environmental problems of off-shore drilling and maintain that this land should be left alone and allowed to stand as an environmental

you need to warm one gram of most other fluids by the same amount. This makes water much better for regulating the temperatures of animals and the environment. Water also has a very high heat of vaporization. Converting one gram of cold water into ice requires 80 Calories of energy. Converting the same amount of very hot water into steam requires 540. The high amounts of energy required to change water from its liquid state make water tend to stay a fluid. The process of freezing water involves slowing
everyday situations, such as deciding how much fencing is needed to encompass a designated area. Finding how gravity affects certain objects is how calculus aids people who study Physics. Mechanics find calculus useful to determine rates of flow of fluids in a car. Numerous developments in mathematics by Ancient Greeks to Europeans led to the discovery of integral calculus, which is still expanding. The first mathematicians came from Egypt, where they discovered the rule for the volume of a pyramid
stands for dilation and evacuation. These are preformed up to the twenty-fifth week of pregnancy, and usually take ten to twenty minutes. The way they are preformed is the woman is given absorbent dilators, which open up the cervix and absorb the fluids. After this is left in overnight the woman then is ready for the evacuation stage. The fetus is easily removed with instruments and suction. In the last trimester of the pregnancy abortions are preformed mainly if the woman’s life is in danger or
References 10 2. The ORAC assay – a brief introduction 2.1 Theoretical background The oxygen radical absorbance capacity (ORAC) assay is a method for measuring the total antioxidant activity in a biological sample. Biological samples include body fluids of animals and humans (serum, plasma, urine, saliva), plant extracts, agricultural and food products, and pharmaceutical products.[6] The advantage of the ORAC assay is the wide range of applications as it can be used for both lipophilic and hydrophilic
Filovirus, and that is Marburg. Ebola has a 90% death rate, whereas, Marburg is not as deadly. Their long and ropelike shape rather than roundness, as is most other viruses, characterize Filoviruses. Ebola is contracted very much like HIV: bodily fluids such as blood, vomit, sharing needles, and sexual contact. The only difference is that Ebola can be transmitted from the close contact of an infected person, which is the most common means of infection. This is possible because the Ebola virus has
you. The overalls will protect your clothes from getting drenched and muddy. The last thing that you should never leave the dock without is plenty of liquids to drink. I recommend Gatorade or water, but no soft drinks. It is very hot on the boat and fluids are a necessity so that you do no dehydrate. Before you can start crabbing, you need certain materials. The most important is a commercial license to sell crabs. A license can be purchased from the Game Warden in Richmond Hill. You must go early in
