ABSTRACT

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, shapes/roundness 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. Lithozone - The probable reservoir rocks occupy Lithozones: 2, 3, 7, 9, 10, ,13, 15, 16, 17, 18, 21, 27, 29, 32, 33, 35, 36, 37, 39, 42, 43, 45, 46, 47, 48, 50, 51, 52, 54, 55 56, 58, 62, 72, 86.; and potential source rocks occupy Lithozones: 1, 4, 5, 8, 11, 12, 14, 20, 22, 23, 24, 25, 26, 31, 34, 40, L 49, 53, 57, 59, 60, 63, 65, 67, 71, 73, 76, 77, 78, 79, 80, 83, 85, 87, 88. The environment of deposition penetrated was parallic environment with the intercalation of sand and shale.
