Monitoring the effects of hydraulic stimulation by microseismic event location: a case study
One of the most promising techniques for monitoring the effects of hydraulic stimulation or fracturing is the use of the induced microseismicity to define the shape and orientation of the stimulated regions. The results presented in this work are believed to be the first of their kind with an on-line location system mapping the stimulated zone during injection. The stimulation was undertaken as part of an investigation into the generation of hot dry rock geothermal reservoirs and consisted of a 3.5-million gal injection at flow rates as high as 40 bbl/min. Many thousands of microseismic events were produced, located, and presented as maps to enable the interpretation to proceed during the operation. These results represent a considerable step forward in the state of the art of monitoring hydraulic stimulation and have been an essential tool in understanding the geothermal reservoir performance. 28 references.
