However, the process of hydrofracking has been highly criticized. Natural gas movement through shale formations occurs mostly through cracks in the rock called joints; therefore a well that intersects these joints produces the most natural gas. Traditionally, gas wells were drilled vertically into the rock, but the joints in the Marcellus Shale tend to run vertically, so traditional, vertical wells would intersect very few joints and hence produce little gas. Hydrofracking works by drilling a vertical well down to the shale layer and then drilling horizontally into the shale. The fracturing part of the hydrofracking involves pumping a high-pressure gel down into the well with enough force to fracture the rock and release the natural gas trapped inside…
Each gas well requires an average of 400 tanker trucks to carry water and supplies to and from the site…
The need for oil and gas to be drilled on American soil is growing. The need for oil and well rigging and oil riggers increases daily. Despite being an extremely dangerous field to go into, oil rigging is a sought after job. As the popularity of oil rigging increases, the danger of doing so will increase as well and the concern for those working with oil welling rises.…
The entire fracturing operation takes places near the well site that connects the underground resource. The drill hole turns horizontal once it reaches the depth of the resource so as to increase the area of the well exposed to the…
decreased flow tube radius. Which mechanism do you think will have the greatest compensatory effect?…
Once the mixture reaches the end of the well the high pressure causes the nearby shale rock to crack thus creating 'fissures ' where natural gas flow up and into the well. During this process methane gas and toxic chemicals leach from the system and contaminates nearby ground water. Methane concentrations are 17x higher…

The fluids made of water and chemical additives are then pumped into a geologic formation at high pressure during hydraulic fracturing. When the pressure of the fluid surpasses the rock, the fluid opens the fractures and extends hundreds of feet away from the well. Once this is done, a propping agent is pumped in the fractures to keep them from closing back up when the pressure is let go. After the fracturing is done, the pressure of the geologic formation causes the injected fluids to rise to the top where it is saved in tanks or pits before disposal or recycling. Any recovered fracturing fluids are called “flowbacks” and is then disposed of into surface water or through underground injection.…
In order to make sure the safety of contamination, the companies have to pay extra attention to make sure the pipes do not have cracks. Additionally, with different ground levels, between the tubing and pipes for each supply, many believe that contamination is unlikely to happen. Throughout the history of fracking, there has been research showing that the amount of incidents have reduced because "between 2008 and 2011, only a handful of major incidents happened across more than 3,500 wells in the Marcellus (Yale)." Many people believe that the operations and the process of fracking could be improved as time pass by with the advance and new…
Attached is a copy of the crash cart layout. IV tubing was located in the second draw of the crash cart. We are having major problems with clinics. 5 west had 2 codes within 3 hours' time span. Cart number was 37 and 52 on 02/10/2017. MICU had 2 code blue around 1725 (5:25pm) cart number 1 and 28 on 02/13/2017. 5 east had a code 02/14/2017 Cart number 52 and the IV tubing was in the second draw of the crash cart. I don't understand what is going on with these clinics keep going into these crash cart for no reason other than don't want to come to windows for supplies they need for their clinic. Please help us get this under…
Williston is the heart of Bakken oil country, the Fort McMurray of the U.S. 's north, for all the good, and bad, that brings. There are at least 3.1 billion barrels of recoverable oil trapped in the Bakken shale, a teardrop-shaped formation spread between North Dakota, eastern Montana and Saskatchewan, and likely many billions more. In recent years, new technology and high prices have made that oil both easier to get at and more valuable to sell. Today the race to pump it out--via a complex process known as hydraulic fracturing or "fracking"--is running at an Olympic pace.…
