Research ArticleOpen accessPhrase in the titleSeismic Refraction Method: A Technique for Determining the Thickness of Stratified SubstratumOchuko AnomohanranThe seismic refraction survey is a very important geophysical technique used in the investigation of subsurface characteristics. This is why this study was carried out to emphasize the ability of the seismic refraction method in determining the thickness of stratified layers of soil and rock. The results obtained are generalized expressions that relate travel time, offset distance, velocity and thickness … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,684 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleDOWNHOLE 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 PDF Cite

Research ArticleOpen accessEvery word in the titleGeoelectrical Resistivity Imaging and Refraction Seismic Investigations at Sg.Udang, MelakaZeinab Asry, Abdul Rahim Samsudin, Wan Zuhairi Yaacob, Jasni YaakubProblem statement: A Reconnaissance geophysical survey of an area near Sg.Udang, Melaka was conducted using geoelectrical resistivity and seismic refraction methods. The main objective of this study is to determine the depth of bedrock in the study area.

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 · 11,449 accessesView PDF Cite
