Abstract: In recent years, ground penetrating radar (GPR) has been widely used as a technical means to understand the characteristics of subsurface geological deposition. However, there has not been any ground penetrating radar to recognize the internal configuration of the dam. The aim of this study is to form a composite dam with a point bar stack. Firstly, the highest resolution frequency of GPR is selected, and then the data are taken in the study area. And eliminate the influence of various factors on data volume. On the basis of the previous work, the location, the formation mechanism and the spatial distribution of the composite dam are determined by measuring the location of the point dam overlap and the dip angle, inclination and thickness of the lateral accretion.
Keywords: Ground penetrating radar; Field trench; the meandering river point bar; Point dam configuration.

Abstract: Miospore biozonation carried out on ditch cutting rock samples has been used to delineate the Upper Miocene/Pliocene sediments in well X, deep offshore, Niger delta. The rock succession is characterised by the alternation of sand and shale of variable thicknesses with lateral gradation in grain size. The base of the studied interval is made of Black shales intercalating with medium to coarse grained, sub rounded to rounded sandstone and siltstone at intervals representing the paralic Agbada formation while the top is made of Sub angular - sub rounded quartz pebble conglomerate, pebbly sandstone, medium - coarse grained, sub- rounded to well-rounded sandstone, intercalating with very thin lenses of grey shales typically...............

Abstract: Palynological investigation of the ditch cutting rock samples from well Z, offshore Niger Delta has been carried out. The rock succession is characterised by the alternation of fossilferous grey sandy shale with shells and shell fragments intercalating with medium - coarse grained, sub rounded to rounded sandstone with scattered mica flakes with appreciable thickness at the base and more paralic at the top, characteristically of the paralic Agbada Formation . palynological analysis yielded a well preserved and well distributed biostratigraphic relevant Miospores among which fifty...............
