importance of sediment storage has been expressed as being higher than that of water in floodwater spreading networks. to determine the contribution of each geological formation in sediment input of gachsaran floodwater spreading station after 12 years of flood spreading, sediment sampling was conducted in 16 points and 0-15 cm depth of the field. using dry sieve analysis, all samples were anal...

Two stratigraphic sections (Kuh-e-Rahmat and Kuh-e-Sabz) of Upper Cretaceous strata in the Interior Fars region (SW of Iran) were selected. Lower Cretaceous succession of Kuh-e-Rahmat was consisted of Dariyan, Kazhdumi Sarvak and Ilam Formations. The lower contact of the Sarvak Formation with Kazhdumi Formation is described as a transitional type whereas the upper contact of Sarvak Formation wa...

in order to determine the physico-chemical characteristics of oils from upper sarvak and dariyan formations, 4 oil samples collected from reshadat and resalat oilfields were analyzed. physical properties of oils (e.g. the api gravity), indicates that dariyan oil in both resalat and reshadat oilfield is similar to (with low pour points and high sulfur contents) the oils from sarvak reservoir. ba...

three well - known source rocks of the zagros basin and the persian gulf are mesozoic in age.the jurassic sargelu, albian kazhdumi and neocomian-coniacian garau formations have charged the cretaceous reservoirs of this area. the northwest part of the persian gulf is strongly influenced by two major n-s trending paleohighs (hendijan- bahregansar-regesafid-izeh and kharge- mish) and surrounding p...

physical and chemical properties of  crude oil, including viscosity and api gravity, are commonly inherited  from the  early organic matter, environmental conditions in which they were deposited and depth of burial of the source beds. api gravity increases in deeper burial due to higher thermal maturation of organic matter in the source rocks and consequently, generation of lighter saturated hy...

The main rock mass classification systems make use of similar rock mass parameters. Due to lack of comprehensive estimation systems, determining the real specifications of jointed rocks faces some difficulties. A vast number of parameters with various degrees of impact are involved in such definitions. Combination impact of all the effective parameters is to be figured out in order to come up w...
