pressure; this part of the process allows the gas to flow to the head of the well and outward. Geological formations often contain large amounts of valuable gases and oils but have a low permeability leading to poor flow rate. The combination of hydraulic fracking and horizontal drilling has been able to address this problem‚ opening the shale deposits

Wittfogel was that of ‘hydraulic civilizations’ (Minnery 2010a). Hydraulic civilizations were described as those whose agricultural system was reliant upon significant government-directed water systems for irrigation and flood management (Encyclopædia Britannica 2010). Wittfogel listed that Egypt‚ India‚ Mesopotamia‚ Northern China and pre-Columbian Mexico and Peru were examples of hydraulic civilizations (Minnery 2010a). This paper will focus on the theories of the Wittfogel’s hydraulic civilization and

Hydraulic Fracking is a hot topic these days within the media of Ohio and locals of Licking County‚ Ohio. What issues and risk do we seem to currently need to be aware of? Could properties of local residents be affected and what step(s) are we taking to insure a brighter future for Ohio? Fracking‚ also known as‚ hydraulic fracturing is the idea of using hydraulic pumps mixed with water‚ sand‚ and chemicals to break rocks apart at high pressures which then will release gasses.

which would relate to the topic of Hydraulic Fracturing. What is Hydraulic Fracturing you may say? According to Propublica.org‚ Hydraulic Fracturing is the process used in 9 out of 10 natural gas wells in the United States‚ Where millions of water‚ sand and chemicals are pumped underground to break apart the rock and release the gas. The main purpose for Hydraulic Fracturing is due to its inexpensive extraction. Over the past decade‚ the combination of Hydraulic Fracturing and horizontal drilling

Course Project Week 2 ReyDel Veenstra Hydraulic Fracturing What is Hydraulic Fracturing: Hydraulic fracturing or “fracking” is a well stimulation process used to maximize the extraction of underground resources including oil and natural gas. Hydraulic fracturing involves the pressurized injection of a mixture of water‚ chemicals‚ and sand in underground formations to allow natural gas and oil to flow more freely from rock pores to the surface.
