pdf Sequence stratigraphy based on Kazhdumi Formation logging data, Southwest of Iran
*The article is presented in English.

The Albian to Campanian sequences (Kazhdumi, Sarvak, Surgah and Ilam Formations) in Zagros basin belong to the Bangestan Group. Kazhdumi Formation with the Albian age in this basin has a particular importance due to its hydrocarbon generation potential in most of Iran's oil fields.
In this research, we calculated the shale volume based on two methods: linear method and neutron porosity cross-plots. From these two results, we choose the minimum value due to: Fundamentals of Log Interpretation. The shale volume in two wells 1 and 2 in the Azadegan oil field in the north of the Dezful structural zone has been calculated using gamma ray log and neutron-density and neutron-porosity cross plot. The sequence stratigraphic analysis by the Pruned Exact Linear Time algorithm of the studied sedimentary rocks in two wells shows that the Kazhdumi Formation in wells 1 and 2 consists of 69 and 76 sedimentary sequences of the 5th order, respectively. This sedimentary sequence includes transgressive sequence systems tracts, highstand systems tract and low stand systems tract.

Keywords: Kazhdumi Formation, Azadegan oil field, Pruned Exact Linear Time algorithm, sequence stratigraphy, transgressive sequence systems tracts, highstand systems tract, low stand systems tract, Southwest of Iran.

pdf Modeling the effect of fracture orientation on porus media anisotropy using the T-matrix method
*The article is presented in English.

Fracture orientation is crucial in porous media anisotropy. In the current study we investigate the role of fracture orientation based on a novel Rock Physics method - the T-matrix approach. This method allows us to study the fracture porosity, shape and orientation together with the minerals volumetric and morphological characteristics. In the first part of this paper, we assume that the considered system consists of a set of aligned, penny-shaped fractures. To include the fracture's spatial alignment, we use the Euler angles. The sensitivity of the stiffness components on the main diagonal of the stiffness matrix along the extended Thompson parameters to the fracture orientation change was investigated.
Based on the obtained results we concluded that the effect of fracture orientation on the anisotropy of the system can be explained by introducing a hypothetical qualitative parameter called the fracture projection cross-sectional area on the three perpendicular planes (x1, x2 and x3). We developed three basic rules to describe how fracture alignment controls this hypothetical parameter.

Keywords: аnisotropy, T-matrix method, Euler angles, stiffness matrix, fracture orientation.
