Sequence Stratigraphic Analysis of Well BB-3, Deep Offshore, Niger Delta Basin, Nigeria: Insight from Palynological Studies

Autor: H.O. Usman, C.I. Unuevho, J. N. Chukwuma-Orji, Y. B. Alkali

Sequence stratigraphic analysis was carried out on well BB-3, deep offshore, Niger Delta Basin, Nigeria. This is done in order to delineate sequence stratigraphic surfaces using vertical sequence of depositional environment. Palynological analysis wa

Depositional Environment Reconstruction of OM-4 and OM-A Wells, Niger Delta, Nigeria, Using Palynomorphs and Wireline Logs

Autor: E A Okosun, O M Taiwo, A I Goro, Y B Alkali

Publikováno v: Universal Journal of Geoscience. 7:31-42

Microfacies analysis combined with palynological studies were carried out on two wells (OM-4 and OM-A wells) in the Niger Delta to reconstruct the depositional environment of the penetrated wells from 8200 – 11350 ft each in both wells. The success

Autor: J. Yisa, Y. B. Alkali, H. O. Nwankwoala, P I Olasehinde, A.N. Amadi, E A Okosun

Publikováno v: Journal of Geo-sciences. 2:51-59

The quality of groundwater in the coastal aquifer of eastern Niger Delta has been assessed in the present study using Geostatistical techniques. The range, standard deviation and variance of the dataset show that multi-chemical processes are controll

The Geochemistry, Origin and Reserve Evaluation of Sokoto Phosphate Deposit, North Western, Nigeria

Autor: Y. B. Alkali, E. A. Okosun

Publikováno v: Earth Science Research. 2

Sedimentary phosphate occurs as thin nodular beds and nodular disseminations in the Dange Formation (Paleocene) of Sokoto basin in north western Nigeria. The geochemistry, origin and reserve evaluation of the phosphate in the Kasarwasa Prospect have

Autor: I. C. Ogbonnaya, J. Yisa, Y. B. Alkali, J. O. Jacob, M. A. Dan-Hassan, A. N. Amadi

Publikováno v: Journal of Geography and Geology. 4

In this study, metal pollution index (MPI) and principal component analysis (PCA) techniques were applied to water quality data sets obtained from River Chanchaga, Minna, North-central Nigeria, to obtain the spatial and temporal changes in the river

Autor: J. N. Chukwu, I A Okunlola, Y. B. Alkali, N O Okoye, A. N. Amadi, T. A. Ako, P I Olasehinde

Publikováno v: Journal of Geography and Geology. 4

Gamma ray Spectrometer (DISA-300) and broadband gamma ray scintillometer (BGS-ISL) were used to evaluate the radiometric properties of rocks (Igneous, Sedimentary and Metamorphic) in parts of southwestern Nigeria. The study revealed that although the
