Monitoring the Effects of Hydraulic Stimulation by Microseismic Event Location: A Case Study

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