Sedimentological Resolution Of Hydrocarbon Play Elements Of OGE-1 Well Greater Ughelli Depo-Belt Niger Delta Basin.

One hundred and thirty six 136 side wall core samples gotten from the well were subjected to lithological description with the aim of determining the various lithofacies and hydrocarbon play elements in the well. Physical characteristics such as colour texture hardness fissility shapesroundness of rock were noted. Four major lithofacie were typified by the lithologic model they include sandstone shale sandy shale and shaly sand respectively. The sedimentary succession penetrated reveals Eighty eight 88 lithozones from bottom to top. Mineralogical assemblages present are iron and mica. The lithologic model of the sedimentary succession penetrated reveals nineteen 19 potential petroleum reservoir rocks Twenty three 23 potential source rocks and fifteen 15 caprocks.

The environment of deposition penetrated was parallic environment with the intercalation of sand and shale.
