Fracking And Fracture Stimulation Techniques Essay

Fracking in CSG mining is a process where a mixture of water, sand and additives are pumped under pressure into a coal seam to open up already existent cracks in the coal strata. Fracturing fluid is 97%-99% sand and water, with a small amount of commonly used biodegradable compounds to prevent bacterial growth and turn the fluid into a gel so it can be pumped more easily (What is coal seam gas? - NSW Resources and Energy, 2016). The CSIRO suggests the components of fracturing fluid are: guar gum, sodium hypochlorite, sodium hydroxide, ammonium persulphate, ethanol, acetic acid and sodium carbonate. Any chemicals used in fracking activities in NSW must be approved by the NSW Department of Industry, Resources and Energy. This government agency assesses applications to determine the chemical use is safe for both the community and environment. Additives of drilling and fracture stimulation techniques may be sampled at any time to ensure compliance with government legislation. In some places the coal is permeable and therefore fracking is not required to release the gas. In other places gas companies drill horizontally into the coal seam as an alternative to fracking. ‘Horizontal drilling occurs at deep levels underground and reduces the number of visible vertical wells located above ground’(NSW, 2013). The horizontal holes are much smaller and eliminate the need for hydraulic fracking. Hydraulic fracking is not a new procedure and has been used by the oil and gas industryShow MoreRelatedFracking And Its Early Technological Advancements1564 Words   |  7 Pages â€Æ' Contents Introduction 1 What is Hydraulic Fracking? 2 The Roberts Torpedo, 1864 3 Kelpper Well No. 1, 1947 5 Hydrafrac, 1949 6 The Growth of Hydrafrac, 1949 - 1954 8 Introduction Hydraulic fracking (‘Fracking’) dominates the US oil and gas industry.

People have used fracking to produce more than one million oil and natural gas wells since 1947. Currently fracking accounts for 50% of locally produced natural gas and 33% of local petroleum† (Engelder 274). It proved that fracking is valuable because people can get too much natural gas and petroleum from fracking. There are 2.5 million frac jobs that hadRead MoreMotivation: India energy scenario: Today, India is the fifth largest energy consumer in the world.1500 Words   |  6 Pagessuch as quartz and calcite. Shale can be the source, reservoir and the seal for natural gas. Shale formations normally have low permeability (limited ability for gas or fluids to flow easily through the shale formation) and normally require stimulation techniques (such as fracturing) to economically produce shale gas. Shale gas is natural gas that is attached to, or â€Å"adsorbed† onto, organic matter or is contained in thin, porous silt or sand beds interbedded in the shale. The combined clay and mineralsRead MoreHydraulic Fracturing : A Common And Widespread Technique1637 Words   |  7 PagesHydraulic fracturing has become a very common and widespread technique, especially in North America, due to technological advances that have allowed extracting natural gas from so-called unconventional reservoirs (tight sands, coal beds and shale formations). The socalled high volume hydraulic fracturing (with treatments typically an order of magnitude larger than the conventional fracturing procedures) began in 1968. This was complemented by horizontal drilling since the late 1980s, and the useRead MoreFracking : Hydraulic Fracturing ( Fracking ) Essay1505 Words   |  7 PagesAlqatami Hydraulic Fracturing Fracking process is a type of drilling water beneath the earth surface in order to access to natural gas and oil. A huge drill is used to pass through many layers of earth and rock that lie between us as the natural gas. The mixture is water, sand and certain chemicals forced into the rock at high pressure in order to force the gas out to where they can collect it. The drill can be driven into the earth either vertically or horizontally.
