Research ArticleOpen accessEvery word in the titleContinuous Wavelet Transform Based Spectral Decomposition of 3d Seismic Data for Reservoir Characterization in Oyi Field, se Niger DeltaChukwuemeka Ngozi Ehirim, Andifon Sylvester AkpanContinuous Wavelet Transform (CWT) is one of the most used wavelet transform based spectral decomposition methods in the direct detection of hydrocarbons and as an indicator of stratigraphic variability due to its optimal time-frequency resolution and variable time window requirements. CWT based spectral decomposition was applied on a 3D Post Stack Time Migrated (PSTM) seismic data acquired over a producing … …American Journal of Applied Sciences, Vol. 14, Issue 8 · 28 Apr 2017 · 7,791 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Contribution of the CDP Gathers and Pre-Stack Seismic Inversion in the Prospect Evaluation: A Case Study of El Mansoura Field, Nile Delta, EgyptMohamed Hussein, Ahmed Abu El-Ata, Mohamed El-BehiryThis case study showing the usefulness of the Common Depth Point (CDP’s) analysis to assess the amplitude response which is similar at two cases (gas-bearing and dry sands) after stack, using the Amplitude Versus Offset (AVO) analysis and the pre-stack inversion to understand the reservoir configuration and its relationship to the different amplitude response. The results led to a high … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 24 Jul 2019 · 7,794 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPlane Versus Elastic Wave AVO Anisotropic Synthetic Modeling in Derby Field, Southeastern Niger DeltaChukwuemeka Ngozi Ehirim, Nnamdi Ogbonna ChikezieAVO based Zoeppritz’s plane wave and elastic spherical wave anisotropic synthetic modelling have been investigated in Derby field, Southeastern Niger delta. The objective of the study is to investigate the influence of anisotropy on plane and elastic wave AVO synthetics modeling over shale-gas sand horizons in the field. Well log data was check shot corrected and correlated with pre-stack data … …Current Research in Geoscience, Vol. 7, Issue 1 · 6 May 2017 · 7,896 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDOWNHOLE SEISMIC REFRACTION SURVEY OF WEATHERED LAYER CHARACTERISTICS IN ESCRAVOS, NIGERIAOchuko AnomohanranThe problem of datum correction in seismic surveys and the failures associated with civil engineering structures with specific reference to roads and buildings has been attributed to lack of understanding of the soil structure among others. This is why this survey on downhole seismic refraction was conducted from nine borehole locations in Escravos, Nigeria to determine the weathered layer characteristics … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 30 Dec 2013 · 7,738 accessesView PDFCite

Research ArticleOpen accessIn the abstractOn the Problem of Stratigraphic Assignment of the Key Seismic Horizons on the East-Arctic Shelf and in the Area of Central Arctic UpliftsLidia Daragan-Sushchova, Lyudmila Grinko, Natalia Petrovskaya, Yuri Daragan-SushchovModern geological and geophysical studies of Central Arctic uplifts area and East-Arctic Shelf has revealed the basic problems in stratigraphic subdivision of sedimentary cover. Basic approach for subdivision of Arctic Ocean sedimentary cover is based on the wave field's characteristics and tracing of regional seismic horizons. Their age identification still depends on general geological ideas. Different correlative models of seismic-stratigraphic … …Current Research in Geoscience, Vol. 5, Issue 1 · 16 Jul 2015 · 7,993 accessesView PDFCite
Research ArticleOpen accessIn the abstractSH Waves Diffusion in Fluid-Saturated MediumC.C. Dennis Ling, S. Y. Faisal, A. A. ZainalProblem statement: Characteristics of the seismic waves have been studied mainly the amplitudes, attenuation, frequency, porosity and the velocity of the waves. In this study, the SH-waves were studied for the diffusion which was related to the diffraction of SH-waves in the saturated medium. Approach: The elastic wave equation was being used to show the SH-waves. A comparison was made … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,333 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Liquefaction Return Period for Bangalore Based on Standard Penetration Test Data: Performance Based ApproachK. S. Vipin, T. G. SitharamProblem statement: The conventional liquefaction evaluation is based on a deterministic approach. However in this method the uncertainty in the earthquake loading is not properly taken into account. However recent research in this field indicates that this uncertainty in the earthquake loading has to be considered in the liquefaction potential evaluation. Moreover the evaluation of liquefaction return period is not … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 7,741 accessesView PDFCite
