Development of facies model and comparison of Darvin kupesi and Pirallahi fields

Abstract

The paper reviews two mature fields in long-term development. Both of them have a tectonically complicated structure. Although the fields have been developed since last century, they have quite large oil reserves. Due to this, the structural-lithologic framework of the fields, the lithofacies composition, the balance, and recoverable reserves, as well as the parameters of development have great significance. Our task is the specification and estimation of lithofacies properties of field data. The lithofacies of neighboring Darvin kupesi and Pirallahi fields have not been enough studied. The types of facies of sedimentary rocks of Girmaki, Lower Girmaki, and Gala suites have been researched and 3D models have been developed, the comparisons of the models have been carried out as well. As a result, the changes were observed both by the area and the depth.
