Low-frequency microtremor anomalies at an oil and gas field in Voitsdorf, Austria
ABSTRACT Results of a passive microtremor survey at an oil and gas field in Voitsdorf, Austria, are presented. The survey consists in six parallel profiles approximately 9 km long over two hydrocarbon reservoirs. For each profile the seismic wavefield was recorded synchronously at 11 in‐line station...

Results of a passive microtremor survey at an oil and gas field in Voitsdorf, Austria, are presented. The survey consists in six parallel profiles approximately 9 km long over two hydrocarbon reservoirs. For each profile the seismic wavefield was recorded synchronously at 11 in‐line stations. The measurements were conducted with broadband seismometers and lasted, for each profile, at least 12 hours overnight. Data interpretation is based on a comprehensive data set and on the analysis of four different spectral attributes. These attributes quantify the characteristic features of the wavefield's Fourier spectra in the low‐frequency range (<10Hz). One attribute quantifies the spectral energy in the vertical wavefield component, another attribute quantifies the maxima in vertical‐to‐horizontal spectral ratios and two attributes describe the frequency shifts of peaks within the spectra of vertical and horizontal wavefield components. Due to temporal variations of the signals we combine the long‐term measurements (several hours of continuous records) of multiple profiles. This procedure considerably enhances the consistency of each spectral attribute and makes them suitable to quantify lateral variations of the wavefield. The results show that using a combination of several attributes significantly increases the reliability of detecting anomalies in the microtremor wavefield that are presumably caused by hydrocarbon reservoirs. A numerical study of two‐dimensional seismic wave propagation is applied to investigate the peak frequency shift attributes. The results of the study indicate that the attributes may contain information on the depth of hydrocarbon reservoirs, assuming that the reservoir acts as a (secondary) source of low‐frequency seismic waves.</description><identifier>ISSN: 0016-8025</identifier><identifier>EISSN: 1365-2478</identifier><identifier>DOI: 10.1111/j.1365-2478.2008.00734.x</identifier><identifier>CODEN: GPPRAR</identifier><language>eng</language><publisher>Oxford, UK: Blackwell Publishing Ltd</publisher><subject>Applied geophysics ; Earth sciences ; Earth, ocean, space ; Exact sciences and technology ; Internal geophysics</subject><ispartof>Geophysical Prospecting, 2009-05, Vol.57 (3), p.393-411</ispartof><rights>2009 European Association of Geoscientists & Engineers</rights><rights>2015 INIST-CNRS</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-a4344-893227827255007229a383f995ba9b23ad86e63b9b592d8286d72087ae782bd53</citedby><cites>FETCH-LOGICAL-a4344-893227827255007229a383f995ba9b23ad86e63b9b592d8286d72087ae782bd53</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1111%2Fj.1365-2478.2008.00734.x$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1111%2Fj.1365-2478.2008.00734.x$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,776,780,1411,27901,27902,45550,45551</link.rule.ids><backlink>$$Uhttp://pascal-francis.inist.fr/vibad/index.php?action=getRecordDetail&idt=21304370$$DView record in Pascal Francis$$Hfree_for_read</backlink></links><search><creatorcontrib>Lambert, Marc-André</creatorcontrib><creatorcontrib>Schmalholz, Stefan M.</creatorcontrib><creatorcontrib>Saenger, Erik H.</creatorcontrib><creatorcontrib>Steiner, Brian</creatorcontrib><title>Low-frequency microtremor anomalies at an oil and gas field in Voitsdorf, Austria</title><title>Geophysical Prospecting</title><description>ABSTRACT
