 | Chesapeake Energy hydraulic fracturing method May 24th 2012, 21:52 | In order to maximize the production potential for a natural gas well, the shale formation must be hydraulically fractured. This video outlines and demonstrates the hydraulic fracturing process in Chesapeake Energy natural gas operations. For more information on fracking, visit www.hydraulicfracturing.com. In order to maximize the production potential of the well, the shale formation will be hydraulically fractured. In preparation for the fracturing process the casing will be perforated in the horizontal portion of the well using tubing conveyed perforating guns containing explosive charges. The perforated intervals are spaced approximately 50 to 80 feet a part and creating connection between the production casing and the shale formation.With the initial perforating complete the tubing and perforating guns are pulled to the surface and the work over rig is replaced by a hydraulic fracturing crew consisting of a number of high pressure pumps and blending equipment. This equipment will pump a mixture of water and proppant usually sand through the newly created perforations in the production casing and into the shale formation. First, water is passed from a water storage impoundment into the blue working tanks depicted on this location.The water is then pulled in to a hydration unit which provides the ability to gel the fluid before it is transferred to the blender. At the blender proppant and a small amount of chemicals that aid in the fracturing process are added. The <b>...</b> | Views: 8592 5 ratings | | Time: 03:35 | More in Education |
