“…Since the first clear observation of induced earthquakes in Rocky Mountain Arsenal, during 1960s [Healy et al, 1968] the occurrence of earthquakes has been linked to fluid injection and particularly an increase in pore fluid pressure [Raleigh et al, 1976]. Since 2010, moderate-sized earthquakes were reported to be associated with fluid injection resulting from recent energy development technologies in the oil and gas industry [Horton, 2012;Gan and Frohlich, 2013;Frohlich and Brunt, 2013;Barnhart et al, 2014]. As a result, there has been a significant increase in the seismicity rate in the central U.S. [Ellsworth, 2013].…”

The recent increase in earthquake activity in the central U.S. has led to concerns about the hazard posed by induced earthquakes. Understanding earthquake phenomena and monitoring in all settings can be improved by the detection of small events; however, the catalog of induced earthquakes is incomplete for small events due to the sparse instrumentation. This is particularly true in settings of low background seismicity, like the central U.S. We apply single‐station template matching to detect small earthquakes during the Guy‐Greenbrier sequence in central Arkansas and find over 100 times more earthquakes than are registered in the Advanced National Seismic System catalog between July 2010 and October 2011. A complete catalog over nearly 4 units of magnitude enables us to analyze the magnitude‐frequency distribution of induced earthquakes. We find that earthquakes deviated from the Gutenberg‐Richter statistics during the operation of nearby injection wells but returned to Gutenberg‐Richter statistics after the wells were shut in.

“…Independent determination of Young's modulus from down-hole measurements, 3-D seismic surveys, or laboratory experiments on well bore samples would allow a more quantitative link between surface deformation and reservoir pressure change. Gan and Frohlich (2013) suggested that increasing earthquakes in the Cogdell field, north of our study area, during 2006-2011 were likely triggered by CO 2 injection. However, our study area, which has also experienced significant fluid injection over the same time period, has not experienced a significant increase in seismicity.…”

Hydrocarbon reservoir is a porous and permeable structure in underground that are placed natural accumulation hydrocarbons in a liquid or gas forms and they are isolated by non-permeable rocks from the surrounding environment. Petroleum industry has used a wide variety of methodologies for stimulating the reservoir fluids to obtain the maximum amount of production rate in the surface; this method entails CO 2 injection by transporting to the preferred layers which had the most recovery factor over a period of 35 years. Besides, in terms of fractured reservoirs enhanced oil recovery of these formations were poorly considerable candidates due to the complexity of predicting the productivity of these reservoirs. Oil and injected fluids tend to produce oil through gaps or cracks in the matrix block and cannot be moved easily. The purpose of this research is to gradually increase the extent of recovery by injecting carbon dioxide, methane and water. PVT modules of Eclipse software were being used. By injecting carbon dioxide into the reservoir, Injected Gas due to its gravity drainage move through the fracture of block matrix.
