ERT data are measured twice a day to monitor the internal hydrogeological conditions of the embankment. In this paper, we present the initial assessment of site-specific 3D geometry effects on 2D ERT data measured with the monitoring system. Using average resistivity values of the levee material, 2D and 3D models of the embankment were reconstructed in RES2DMOD and RES3DMODx64. Apparent resistivity pseudosections were calculated for different profiles along the embankment and pseudosections of resistivity differences between 2D and 3D modellings were then calculated for all profiles. The results show that regardless of the lateral position, all measurements along the embankment are distorted by 3D effects, especially in deeper parts. For the smallest electrode spacings, the profile in the middle of the embankment measures data closer to real values. Our next research perspective is to use 3D field measurements and samples of the embankment to more precisely quantify the site-specific 3D effects. Considering that clay is one of the main materials used in constructing this embankment, we also plan to explore the 3D effects on 2D induced polarization (IP) measurements.","PeriodicalId":393867,"journal":{"name":"EAGE-GSM 2nd Asia Pacific Meeting on Near Surface Geoscience and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131849932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the main challenges in acquiring seismic data in this area is the presence of internal multiple. This seismic multiples are usually considered as insignificant compared to the surface-related multiples, however if the target areas lies in a deeper region, it becomes much more prominent due to the weaker primary reflections. If this type of seismic noise is not handled correctly, it can effect the seismic reservoir and characterization and thus increasing the risk in oil exploration. Therefore a more advanced method needs to be applied, and one such method is the inverse scattering series. This method is data-driven therefore unlike other internal multiple attenuation technique, its does not require any prior information of the subsurface to predict the multiple. The application of this method in offshore Malay basin shows significant results, as the seismic data produced shows an improvement with a cleaner image compare to the one without any internal multiple removal.","PeriodicalId":393867,"journal":{"name":"EAGE-GSM 2nd Asia Pacific Meeting on Near Surface Geoscience and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132017206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
