چکیده
dezful embayment contains several potential source rocks deposited in tectonically active environments. existence of various source rocks with different geological ages makes this area one of the most prolific regions throughout the middle east. the pabdeh formation (lower paleocene-eocene), the gurpi formation (santonian-masstrichtian), the kazhdumi formation (albian) and the gadvan formation (neocomian-aptian) are among the most favorable source rocks within the embayment. in this study the set of above mentioned source rocks are subject to pyrolysis in aghajari oilfield. results reveal that the kazhdumi formation with highest toc (4.43%) in compare to other probable source rocks has higher hydrocarbon generative potential and is the likeliest source rock responsible for the asmari and bangestan reservoirs in the aghajari oilfield. moreover, the pyrolysis of pabdeh, gurpi and gadvan formations show that they are of minor importance as potential source rocks within the studied oilfield. the burial and thermal history of the kazhdumi formation was modeled to infer about the probable time of the hydrocarbon generation. according to burial history profile and thermal modeling the beginning of the oil window for kazhdumi formation was dated at 13ma. moreover, the depth of oil expulsion is around 3800m in 9 ma years ago.

متن کاملRelationship Between Depositional Facies and Reservoir Characteristics of the Oligo-Miocene Asmari Formation, Aghajari Oilfield, SW Iran
The present study focuses on facies analysis and the reservoir characteristics of the Asmari Formation in the Aghajari oilfield (located in the Zagros fold-thrust belt, southwest Iran), and how they are linked to depositional environments and reservoir characteristics. This formation consists of about 380 m carbonates with some siliciclastic intercalations. Based on the integration of 1200 m of...

heterogeneity within the orientalist discourse: representation of the orient in womens travelogues and mens paintings
from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...

Systematic fractures analysis using image logs and complementary methods in the Marun Oilfield, SW Iran
Fractures are considered as one of the important structures in fractured reservoirs due to their effect on fluid currents and reservoirparameters such as porosity and permeability. Fracture parameters can only be directly calculated with core and image logs. Cores haveserious limitations, so image logs are the best method. The aim of this study is the systematic fractures analysis of the Asmari...
