Shaniqua McIntosh April 15‚ 2013 Environmental Science Hydraulic Fracturing: The Problem Hydraulic Fracturing or fracking was first introduced in 1940s and has then been a key provider of natural gas and oil worldwide. Despite its expansion and customary use‚ fracking still poses many health and environmental concerns. During fracking‚ pressurized liquids are injected into drilled wells‚ which cause the surrounding rock to crack open allowing gas and oil flow through the fissures

Locklin‚ 1984‚ page 41‚ makes a clear argument why "apparent Upper Jurassic reservoir rocks have not trapped hydrocarbons more frequently." He reasons that potentially “large faults have caused breaking of mineralized seals and created excessive fracturing along a fault plane‚ which allowed for the

CRAFT HYDRAULIC SYSTEM INTRODUCTION Hydraulics is based on a very simple fact of nature - you cannot compress a liquid. You can compress a gas (think about putting more and more air into a tire‚ the more you put in‚ the higher the pressure). If you’re really strong you can compress a solid mass as well. But no matter how much pressure you apply onto a liquid‚ it isn’t possible to compress it. Now if you put that liquid into a sealed system and push on it at one end‚ that pressure is transmitted

Characteristics of a Good Hydraulic Fluid Viscosity Viscosity is a measure of a hydraulic fluid’s resistance to flow. It is a hydraulic fluid’s most important characteristic and has a significant impact on the operation of the system. When a hydraulic oil is too thin (low viscosity)‚ it does not seal sufficiently. This leads to leakage and wear of parts. When a hydraulic oil is too thick (high viscosity)‚ the fluid will be more difficult to pump through the system and may reduce operating

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

RISK OF EARTHQUAKES FROM HYDRAULIC FRACTURING IN THE UK – KEY STAKEHOLDERS PERCERPTION 1.0 Background On the 1st April 2011‚ a magnitude 2.3M earthquake was recorded near the town of Blackpool‚ UK and this was followed on the 27th May 2011 by a second seismic occurrence of measuring 1.5 on Richter scale. These two events occurred close to Preese Hall drilling site‚ where Caudrilla Resources was extracting gas from a shale deposit using a new method called Hydraulic Fracturing‚ often referred to as
