Application

The results of this study could be applicable in exploration, production and development of oil and gas fields located in the Abadan Plain. Therefore, two main producer and developer companies (Arvandan Oil and Gas Company and Petroleum Engineering and Development Company (PEDEC)) and NIOC Exploration Directorate will be the end users of the project.

Importance

The reservoir studies through EOR and FDP projects on the giant HC reservoirs alike Azadegan, Yadavaran and Darquain and some exploration fields located in the Abadan Plain area necessitates that the integrated geological reservoir studies to be fulfilled and accomplished.

Field-scale studies in this area and integrated studies on neighboring Iraqi oil field showed that the Abadan Plain HC fields seem to be different from oil and gas fields located in the Dezful Embayment from the sedimentological and structural point of views. Despite HC traps in the Dezful Embayment that are mainly simple anticline, they aren’t merely structural in the Abadan Plain. Facies and stratigraphic variations along with the structural deformations construct stratigraphic and combination traps in this area. So that it gives rise in reservoir complexity and consequently exploration and production risks in the area.

The main objective of this study will be characterization and mapping of the geological and reservoir properties of the most important reservoir intervals i.e. Ilam, Sarvak, Fahlyian and Gadvan Formations. Investigating of hydrodynamic behavior and reservoir continuity would be another important aim of the study.

To access the objectives multidisciplinary integrated study is essential that is composed of geological, geophysical, petrophysical, geochemical, reservoir and modeling evaluation and studies.

Achievements

The reservoir complexity factors will be identified in the main HC bearing intervals in this study. Also, facies distribution and hydrodynamic maps of the area are the complementary tasks for the future

explorations and field development processes.

Determination of more accurate estimates of reservoir geometry and volume and applying project results to EOR and FDP process are two main achievements of this study.
