Abstract: The sedimentary depositional environments are more important for reservoir evaluation. The Paleocene- Eocene sedimentology and ancient sedimentary environments study in Central Persian Gulf is the subject of the study under the light of 2-D seismic data, as a key data for geological study. The sedimentary rocks physical characteristics effects on seismic data, gives an appearance to the data, which can be a key factor for their evaluation and sedimentary environment reconstruction. These data are useful in any area, for which less data have been collected by drilling, as well as they can be traced for a vast area. For the current study the seismic data are used beside drilling wells data, including cutting description and logs. The study result shows progradation toward northeast, the direction in which there is increase in accommodation space and the sedimentary environments also migrated toward. Based on sediments thickness achieved by 2-D seismic data interpretation, beside seismic profiles, the deposits are precipitated in shelf, slope and basin environments. Also in some horizons, the sedimentary environments changes to lagoon, platform and basin. These environments demonstrate suitable condition for carbonates and evaporites precipitation, in Jahrum Formation, which are approved by cutting description. The sediments extension and its trend were revealed as well.
