The surveys were carried out with Omega model resistivity meter. The Schlumberger configuration was employed for the VES while Wenner configuration was employed for the 2D resistivity survey (Constant Separation Techniques). The obtained VES and CST data were interpreted using WinResist and DIPRO respectively. The integrated results revealed three to four geo-electrically polluted materials as highly saturated fills (15 Ωm, 1.9 – 27.4m), saturated fills (15 - 30 Ωm, 3.6 – 29.9m) and unsaturated fills (30 - 70 Ωm, 8.1 – 37.1m) underlain by sand formation. A good correlation was established between the thickness of the different fills delineated from the VES and CST results to a depth of 30m. Based on the integrated geophysical investigation, it is therefore concluded that aquifer units within and underlying the sand layer around Ile Epo Dumpsite and environs are potentially polluted. However, for groundwater exploration, aquifers at deeper depth are likely to be free from contamination but required time to time monitoring because the underlying sand layer serves as possible migration path to the pollutants, thereby contaminating aquifers within underlying sand layer.&nbsp;</p> Emele Uduma Okpogo Petra Ebisan Wilkie ##submission.copyrightStatement## 2018-09-25 2018-09-25 1614 1625 Sequence Stratigraphy of the Cenomanian - early Turonian Cycle in the Selected wells, Southeastern Iraq http://ijs.uobaghdad.edu.iq/index.php/eijs/article/view/439 <p>Sequence stratigraphic cycle of Cenomanian-early Turonian is composed of (Ahmadi, Rumaila, and Mishrif) formations, which is bounded at top and base by unconformity surfaces.

Sindbad oil field (South of Iraq) is chosen to study goals and it's containing only one well with VSP survey (Snd2) that covering depth from Zubair to Sulaiy Formations and 2D seismic lines of Basrah Survey. The horizons were picked and used with low frequency contents from well data for the construction of low frequency model and it was used with high frequency of VSP to make the high frequency model that compensated to seismic main frequency through inversion process. Seismic inversion technique is performed on post stack of 2D seismic data (2Br2) through Hampson-Russell CGG program. The inversion model of low frequency shows 88.5% matching with relative seismic impedance while high frequency model 93.3% matching with lower error percent. The two impedance sections which resulted from inversion model were convoluted with best wavelet from VSP data to make a new seismic section.
