Research ArticleOpen accessIn the keywordsAssessment of Weathering Layer Characteristics over OPL-135 in the Western Part of the Niger Delta Basin, South-South, NigeriaOkechukwu Frank Adizua, Adekunle Oyemade Sofolabo, Olomu Ivory Obi-EgbediAn up-hole seismic refraction survey was carried out in OPL-135 in the Western part of the Niger Delta Basin, (SS) Nigeria. A total of thirty seven (37) up-hole locations in a (4.0×3.750) km grid configuration were drilled and logged over the prospect. The focal objective for the study was to assess the weathering layer characteristics over the prospect, specifically, to … …Current Research in Geoscience, Vol. 11, Issue 1 · 3 Feb 2021 · 11,456 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 · 7,901 accessesView PDFCite
Research ArticleOpen accessIn the keywordsShort Period Spectral Acceleration Zonation of Tehran a Comparison between Slip and Activity Rates Data’sHadi Jarahi, Noushin Naraghiaraghi, Malihe NadalianThis study presents seismic hazard analysis and provides spectral iso acceleration maps based on slip rate (SR) and also activity rate (AR) of the faults. Nowadays modern seismic design of structures is complicated so special attention to the nature of the seismicity in active seismic zones like Tehran is required. Many studies, based on seismic hazard analysis have been done … …Current Research in Geoscience, Vol. 6, Issue 1 · 18 Feb 2016 · 8,267 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGeobody Architecture and Petroleum Potential of the Yowi Field, Offshore Eastern Niger Delta, NigeriaPrince Suka Momta, Minapuye Isaac OdigiA study on geobody architecture and petroleum potential of the Yowi Field has been carried out by integrating well logs and 3D seismic data. The objectives of this study include: The determination of the lateral continuity of key horizons; identification of gross geobody distribution and architecture; and the petroleum potential of the field. Well log correlation shows that key horizons … …Current Research in Geoscience, Vol. 6, Issue 1 · 16 Dec 2015 · 7,675 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExperimental Evaluation of the Raking Energy in Damping System of Steel Stud Partition WallsSalah Amer, Sameer Hamoush, Taher M. Abu-LebdehNonstructural partition walls are usually specified based on the best practice without any structural design calculations. However, given the likely severe earthquake damage to nonstructural components and the substantial cost of repair to such components, it is imperative that we develop an understanding of the seismic response of the nonstructural partition walls when subjected to earthquake loading conditions. The main … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 6 Nov 2015 · 7,644 accessesView PDFCite
InvestigationOpen accessIn the keywordsInvestigating the Parameters Influencing the Behavior of Knee Braced Steel StructuresEdris Farokhi, Mehrdad GordiniIn Knee-Braced Frames (KBF), the brace is connected to the knee element rather than the beam-column joint. For reasons such as having sufficient lateral stiffness despite its adequate ductile behavior, the concentration of damage in the Double Knee-Braced structural elements and also ease of repair and replacement of these elements after an earthquake, this bracing system is preferred over conventional … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 21 Sep 2015 · 7,814 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPORE-PRESSURE PREDICTION FROM SEIMIC DATA IN PARTS OF THE ONSHORE NIGER DELTA SEDIMENTARY BASINEmujakporue Omokenu GodwinPore pressure prediction in parts of the Onshore Niger Delta Sedimentary Basin using seismic reflection data has been carried out. The Bower’s technique of velocity-to-pore pressure transform was adopted. The seismic velocities were derived from the seismic data using layer cake velocity model and were later compared with the available sonic logs velocities obtained from the area. Parameters in the … …Physics International, Vol. 4, Issue 2 · 20 Mar 2014 · 7,441 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDetection of Subsurface Defects in Concrete Bridge Deck JointsWonchang Choi, Larry Rickard, Taher Abu-Lebdeh, Miguel PicornellProblem statement: The integrity of deck joints in highway bridges plays a major role to determine overall performance of bridge system. As the bridge maintenance program, the defects in deck joints have historically been detected by conventional non-destructive testing and evaluation methods such as visual inspection, chain-dragging and by the detecting sounds under the traffic. Future bridge maintenance challenges will … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 31 Dec 2011 · 7,777 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Viewpoint for Seismotectonic ZoningReza Derakhshani, Seyed Saeed EslamiProblem statement: Seismotectonic zoning has always been used to get access to intracontinental seismic deformation whereas zoning is not enough reliable in regard with small-scale studies. Approach: This research presents a theoretical model on the basis of plate tectonic theory to introduce a new approach to conduct zoning in terms of seismic deformation. Results: The result of this research not … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 7,669 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLiquefaction Susceptibility in the Northern Provinces of ThailandSupot Teachavorasinskun, Pichai Pattararattanakul, Pulpong PongvithayapranuProblem statement: There are quite a few active faults recently found in the western and northern parts of Thailand, which could possibly induce earthquakes of magnitude (ML) of 5.5-6.5. Although seismic design code has been enforced in the area since 1980, the fundamental knowledge on dynamic soil behavior has not been extensively attained. Approach: Collection of existing borehole information in … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,337 accessesView PDFCite
