"Between November 13th, 2012 and November 30th, 2012, the Habanero#4 well was hy-\r\ndraulically stimulated. Induced seismicity was monitored in real-time with a local 7 station \r\nnetwork transmitting continuous waveform data to a central acquisition office located in the \r\nHabanero camp. Additional, 17 offline stations were operated at larger distances in order \r\nto constrain the fault mechanisms of the induced seismicity. \r\nThe current report documents the technical operation of the live monitoring stations and \r\nthe real-time processing of the data. Processing of data recorded by offline stations and \r\nmore detailed data analyses have been performed after the operation was terminated and \r\nare provided in a separate report (GDY035). \r\nThe live monitoring system was operated in 24/7 mode by two seismologists in the field \r\nsupported by two seismologists working from the Q-con offices in Germany. Remote ac-\r\ncess from the German office was established by satellite link. Data was processed with Q-\r\ncon’s in-house software package QUBE. Despite the extremely high seismic event rate of \r\nmore than 2,700 events/day during peak-times, data processing was performed in real-\r\ntime and the processing results (i.e. seismic event detections, hypocenter locations, event \r\nmagnitudes) were provided to Geodynamics Ltd. on a daily basis as part of short-reports, \r\nwhich are attached to this document (Section 6). All automatically determined phase onset \r\ntimes were quality controlled by visual inspection and manually adjusted whenever neces-\r\nsary. \r\nAdditionally, the QUBE traffic light system was operated to stop hydraulic operations in \r\ncase the magnitude of the induced seismicity reached the pre-defined critical level of \r\nM L =3.7. The occurrence of events with magnitudes exceeding M L ≥2.5 (yellow traffic light) \r\nwas reported to Geodynamics Ltd. within less than four minutes. On November 27\r\nth\r\n, 2012 \r\n8:03 UTC, the traffic light status switched to yellow due to the occurrence of a magnitude \r\nM L =3.0 event. \r\nThe monitoring system was operated without noteworthy technical issues and the system \r\nhad no downtimes during the monitoring period. Event triggering was performed using an \r\nSTA/LTA based detector without triggering dead-time. A total number of 27,445 reservoir \r\nevents were detected with magnitudes ranging from M L =-1.6 to M L =3.0. The signal-to-\r\nnoise ratio of 20,734 of these events was sufficient for determining hypocenter locations. \r\nThe resulting seismicity forms a subhorizontal cloud around the injection well with a lateral \r\nextension of approx. 2 square-kilometres. The (apparent) vertical extension is in the order \r\nof several hundreds of metres and is dominated by the hypocenter location accuracy. \r\nSeismic activity is highly organized in space and time, starting close to the injection well \r\nand subsequently migrating away. These characteristics are consistent with previous ob-\r\nservations made during hydraulic stimulations in the same reservoir."^^ . "2013-06-14" . . .
