The joint using of PP-wave and PS-wave information can reduce the multi-solution of reservoir prediction. The construction of conventional elastic parameters is mainly based on PP-wave seismic information. This study investigates elastic parameter construction by using PP-wave and PS-wave elastic impedance jointly. Based on the previous research on PS-wave elastic impedance, a new form of PS-wave elastic impedance equation which can keep consistency with the PP-wave elastic impedance equation is derived. According to the construction formula of conventional elastic parameters, we use PP-wave and new PS-wave elastic impedance instead of P-wave and S-wave impedance to construct a new kind of elastic parameter with the concept of angle elastic parameter. Compared with the conventional elastic parameters, the angle elastic parameters have incidence angle and PS-wave information and can be used as sensitive indicators of reservoir. Both the model and real data show that the angle elastic parameters have high sensitivity to the beneficial reservoir.","PeriodicalId":6840,"journal":{"name":"81st EAGE Conference and Exhibition 2019","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90334666","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}

Several aspects can drive the FWI data optimization towards a local minimum of the cost function, such as the lack of low frequency, the offset limitation, and the presence of alternating high-low velocity layering in the stratigraphic sequence. This risk can be mitigated by geophysically preconditioning the FWI starting model, leveraging multiphysics independent measurement through simultaneous joint inversion. In this multiphysics multiscale approach, the seismic information is valuably coupled with non-seismic observations, with the potential benefit of reducing the non-uniqueness of surface geophysics inversions and increasing the robustness and fitness of the input model for FWI.","PeriodicalId":6840,"journal":{"name":"81st EAGE Conference and Exhibition 2019","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90358689","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}

Due to the complex environment of desert seismic exploration, the noise shows many different properties, such as: non-Gaussian, weak similarity and low frequency characteristics. Because it is highly unpredictable, it can only be qualitatively analyzed. We improves the Kendall’s rank correlation coefficient combining spatial information to investigate the spatial correlation property of the desert noise. Based on this method, the noise with spatial correlation is statistically calculated. The spatial correlation coefficient of the desert seismic data illustrate that the spatial rank correlation coefficient can reflect the noise spatial structure well and quantify the spatial correlation degree of noise. We find that desert noise has a spatially weak correlation property in which inconsistent noise is the main component. In addition, because there are few surface vegetation in desert areas, wind speed is also an important factor affecting the spatial noise of desert noise. Desert noise shows weaker spatial correlation after wind speed increases.","PeriodicalId":6840,"journal":{"name":"81st EAGE Conference and Exhibition 2019","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90465191","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}

It was introduced into seismic data processing to suppress noise and enhance signal quality. We explain the basic mathematic morphology concepts with set theory and define the basic and advanced morphological operations in seismic data processing. Unlike conventional seismic filtering techniques, MMF is a nonlinear operator so that it can more effectively isolate and attenuate seismic noise based on their shape differences from the signal. We apply different types of morphological filter on field (and various stages of processed) data to demonstrate their effectiveness for suppression of both coherent and incoherent noise and results in an improvement of signal to noise ratio.","PeriodicalId":6840,"journal":{"name":"81st EAGE Conference and Exhibition 2019","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89234872","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}

These changes preclude major tectonic events in the Urals and further south, in Central Europe (Faleide et al., 1993; Glorstad‐Clark et al., 2010). This paper focuses on a region located ~150 km to the North of Finnmark, in Northern Norway (Fig. 1). It relates, for the first time, how the geometry and distribution of Carboniferous and Permian mounds relates to vertical movements of the Samson Dome, and adjacent platform areas (Fig. 1a). In essence, this work will demonstrated Samson Dome area presented a much different palaeogeography in the Carboniferous and Permian from the present day, hinting at the presence of sheltered (shallow) platform areas away from the salt structures that are imaged, on seismic data, at present (Figs. 1b and 1c). The identification of such sheltered areas suggests that either: a) older salt structures (pillows, ridges) existed away from the Samson Dome and salt was subsequently withdrawn from below them during the Mesozoic, or b) important vertical movements in the Mesozoic led to the subsidence of Paleozoic carbonate platforms.","PeriodicalId":6840,"journal":{"name":"81st EAGE Conference and Exhibition 2019","volume":"77 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78564912","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}
