Development Corp.‚ cracked the code on what is today considered to be the new gold rush of the energy industry. By successfully commercializing hydraulic fracturing in the Barnett shale deposit‚ Mitchell ushered in a new opportunity for the United States to emerge as the largest natural gas producer in the world. Higher production of shale gas has reduced energy prices over the last five years and has increased U.S. energy self-sufficiency. Since it is viewed as a relatively clean form of hydrocarbon-based

Stop Fracking With the rising global energy demand‚ shale gas has been considered as the next big thing for energy producers. Fracking is a technology use to extract that natural gas stored deep underground. Although fracking can collect plenty of natural gases‚ it has left a number of very serious impacts both on the environment and human health. Air pollution‚ water contamination and threaten human health are the consequences caused by fracking. Air pollution problem is so obvious for the communities

The following findings were obtained: Higher viscosity. | Higher CSOR ate earlier times. | Same permeability with one having low porosity. | Better recovery factor. | Injector well location closer than 5m to the producer. | Higher CSOR and lower recovery. | Optimum rate of steam injection. | Higher CSOR and higher recovery. | Optimum preheating period. | Higher CSOR and higher recovery. | Horizontal shale barrier
