Popis: | Downhole seismic acquired with distributed acoustic sensors (DAS) provides a unique opportunity to record genuinely broadband data with a frequency range varying from sub-milli-Hertz to several kilo-Hertz. As such, downhole DAS is used to detect and track local microearthquakes caused by fluid injection into a reservoir, analyse natural seismicity or look at lower frequency signals like oceanic microseisms. In most cases, the published studies deal with local single-well installations or multi-well installations with the wells located within first kilometres of each other. In the last two years (2020-2022) we acquired continuous DAS data in three different locations across Australia, namely Otway International Test Centre, Victoria, NGL training well at Curtin Campus in Perth and Harvey-3 well, located 120 km south of Perth in Western Australia. In this presentation, we discuss the outcomes of this trial. Open-Access Online Publication: May 29, 2023 |
