Offshore Drilling Essay

1.0 Introduction In underground hard rock mining, drill and blast continues to be the dominant method of fragmenting rock. Blast hole deviation is an inevitable yet undesirable outcome of small diameter, long hole drilling. The objective of drill and blast is to unlock a targeted volume of rock for removal and further downstream processing. However, if poor drill hole accuracy is observed, outcomes may be significantly different to that which are planned and expected, resulting in additional cost

orders depends on the selected drilling method either a) Manual drilling or CNC OR b) Using CNC Drill Assumption 1: Manual Drilling is not done on all the available Manual Drill Presses in parallel. Calculating time taken for Manual drilling and CNC Drilling: = Setup Time + Run Time (Per Hole) * No. of Holes drilled on each circuit board * No. of boards Time taken for Manual drilling =15 + 0.08*500*x where x= number of circuit boards Time taken for CNC drilling = 240 + 0.004*500*x where x=

In addition, the exhibit 2 does not show actual production time which should

Northern Drilling: Introduction Northern Drilling Inc. was established as a subsidiary of Europe’s InterDrilling Corporation, the world’s third largest exploration drilling contractor, in 2006 to take on a new frontier in Canada. A seasoned veteran in the drilling exploration field for more than 30 years, Peter Bremner took the helm as general manager to build its Canadian division as an opportunity to take advantage of a potentially untapped resource ‘goldmine’. Northern Drilling prided itself

measuring the piece in every procedure. From the beginning, when we cut our piece from the steel bar using the Band Saw machine. In the end when we drilled four different sizes of holes in the piece using two different techniques; drilling using the milling machine and drilling by hand. Before we started machining, we were instructed in how to perform measurements using calipers and micrometers, but we mainly use micrometers during the procedure. Then, after a clear explanation of the procedure, measurements

improved version used acid. It wasn’t until the 1990s that a man named George P. Mitchell discovered the idea of combining fracking with horizontal drilling, thus making up our modern day knowledge of fracking. This method of oil fracking has become so popular because for one it produces a very large amount of oil; much more than what original drilling method produces. Another reason is the higher prices for oil in the world. Common knowledge tells us that if a country can produce its own materials

poisonous sludge, slowly poisoning ourselves and all other inhabitants. There are many ways we do this, offshore oil drilling being one of them. Offshore oil drilling is the process of drilling into the earth and pulling up petroleum, a natural fuel source made of decomposed organisms. While there are many positive effects, there are too many negative ones for oil drilling to continue. Offshore oil drilling is too dangerous to be considered safe for use in the ecosystem. Not only is it too dangerous, oil

organisms like plankton, to the ozone layer. Oil extraction should be banned because it endangers thousands of animals and has the potential to destroy their ecosystems, is far too dangerous for workers, and is a major cause of global warming. Oil drilling affects thousands of marine animals in their ecosystems and has caused massive damage before. For example, on April 20, 2010, 210 million gallons of oil spilled into the Gulf of Mexico. It is considered the largest accidental marine oil spill in

Energy Sources Introduction Energy sources have been identified as being vital in running virtually all domestic and industrial operations. There are two types of energy sources; renewable energy sources and nonrenewable energy sources. Renewable energy sources refer to the kinds that are naturally replenished. These include sunlight, the wind, ocean tides, waves, geothermal heat and rain (Tiwari et al., 2012). Nonrenewable energy sources, on the other hand, are the kinds that do not renew themselves

drilled from the ocean floor through powerful offshore oil rigs. Natural seeps can also occur. This is when crude oil that seeps in the ocean water from geologic formations beneath the ocean floor. Despite these risks, the growth of the global oil businesses continue to grow and our need, and ultimately our dependency on it, grow right along with it. Arguably, the greatest impact of off-shore drilling on the environment is indisputable. There are 3,500 drilling rigs and platforms, 79 of them deep-water
