Abstract

Khasib Formation is considered an important formation in the Late Turonian-Early Campanian sequence and represented a transgressive system tract within deep and inner ramp environment, where Khasib Formation was studied in four oil wells, two from Noor oil field they are : (No-1,2), and the others form Amara oil field ,they are (Am-4,5) in Missan governorate ,southeast of Iraq. (Al-Badry,1999).
Five main microfacies had been recognized for Khasib Formation in studied oil wells , they are : grainstone, packstone , Wackstone, packstone –wackstone and mudstone microfacies , and the coarse texture was defined in the lower part of Khasib Formation while the fine texture was defined in the upper part of the studied formation which meaning deepening upward.
Many digenesis processes which effect on the texture also had been detected, some of them were constructive which played positive role in enhancement the porosity while the other represented negative role.
