Detecting karstification processes in hydrocarbon carbonate reservoirs is important because of their porosity, permeability and also the risk associated with their drilling. A very useful technique to locate buried karsts is 3D seismic. In this research, seismic frequency decomposition (spectral decomposition) and seismic inversion techniques used to identify these sub-surface diagenetic featur...
In order to study calcareous nannofossils biostratigraphy, the upper part of Pabdeh Formation and the lower parts of Asmari Formation was selected in the one of the wells in the oil field Parsi in southwest of Iran. The study of calcareous nannofossil led to recognition of 39 species and 16 genera. According to the first occurrence of index species and distribution fossil assemblages, four bioz...
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...
Evaporite minerals form when evaporation is more than precipitation. One of the most important evaporate minerals are calcium sulfate, that have extensive distribution in geologic time. Sedimentary and diagenetic processes, operating within different environments such as shallow margins to deep water, have an important role in the formation of these minerals. Due to the presence of anhydrite as...
Application of artificial neural networks and fuzzy logics to estimate porosity for Asmari formation
The Oligocene–Miocene deposits of the Asmari Formation are located in SW of the Zagros Mountains of Iran. The lower part of the Asmari Formation consists of an evaporite bed that is termed Basal Anhydrite. Seven sections from four different anticlines were selected and sampled for petrographic and mineralogical analyses .The petrographical examinations were carried out using an optical polarize...
among all the geophysical techniques, the magnetotelluric method has improved considerably in recent years and is widely being used in hydrocarbon exploration especially in regions where reflection seismic has difficulties. areas which are covered with high velocity rocks in the near surface are most popular cases. a huge high resolution magnetotelluric investigation was conducted in the sehqan...
