SEDIMENTOLOGICAL STUDY OF THE HARTHA & SAADI FORMATIONS FROM SELECTED WELLS IN QAYARA OIL FIELD NORTHERN IRAQ

The research included sedimentological study of Hartha and Saadi formations in Qayara oil fields: (QY53, QY84, QY82, QY54). The study indicates that the rocks of both formations are composed from limestone, dolomitic limestone, and dolomite which are effected by diagentic processes such as, dolomization, neomorphism, cementation, dissolution, micritization, and compaction. The lower and upper contact between both formations are conformable due to the lithological and facies similarity between them. The essential and secondary microfacies are designated from both formations. The depositional environment of both formations indicate shelf (inner- Middle-Outer) to slope environment
