报告题目：Ambient seismic imaging of hydraulically active fractures at km depths

上午9:00-11:00

报告摘要：

In this work, we illustrate the value of the ambient method in its industrial application by showing case histories from energy industry and carbon-capture-sequestration projects. These include ambient images taken before, during, and after hydraulic treatments in un-conventional reservoirs. The results show not only locations of active fractures, but also their time responses to stimulation and production. Time-lapse ambient imaging can forecast and track events such as well interferences and production changes that can result from nearby treatments.

报告题目：Controlling induced seismicity during hydraulic stimulation of a 6-km deep EGS in Finland

下午2:00-4:00

报告摘要：

In this work, we show that near-real-time seismic observations allowed control of a hydraulic stimulation in a 6.1 km deep Enhanced Geothermal System project in Finland. The injection well, OTN3c, was drilled into Precambrian crystalline rocks. The last uncased 1000 m and 45° inclined part of OTN3c was divided into several injection intervals. A total of 18,159 m3 of water was injected during a period of 49 days in Jun-Jul 2018.
