These were gradually … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 7,194 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPetrophysical Characterization and Flow Models for Agbada Reservoirs, Onshore Niger Delta, NigeriaPrince Suka Momta, John Owate Etu-Efeotor, Charles Ugwu UgwuezeThree selected reservoirs (XB, XC and XE) from three wells (A, B and C) occurring within the Agbada producing sands in part of the Greater Ughelli Depobelt of the onshore Niger Delta have been studied. The study aims at evaluating the petrophysical characteristics of the sand-bodies and also identifies the various flow units present within each reservoir. Petrophysical parameters were … …Current Research in Geoscience, Vol. 5, Issue 2 · 21 Oct 2015 · 7,910 accessesView PDF Cite
