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...

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...

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...

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 ...

in this research, calcareous nannofossils of the upper cretaceous deposits of the souteast lar have been investigated. the upper cretaceous deposits have a thickness of 173 meters and consist of thick layers of marl and marly limestone. for introducing calcareous nannofossil assemblages and biozones, 141 slides of the gurpi formation in southeast of lar area have been studies which led to ident...

the study of planktonic foraminifera of the ilam and gurpi formations at sarvestan area (se of shiraz) enables me to find the most standard biozones defined in mediterranean regions, especially tethysian domain. seven biozones were determined. biozones i (dicarinella concavata zone) and ii (dicarinella asymetrica zone) belong to the ilam formation and indicate the late coniacian-early santonian...

Abstract The challenges behind this research were encountered while drilling into the Ilam, Mauddud, Gurpi, and Mishrif Formations, where severe instability-related issues observed across weaker formations above reservoir intervals. In paper, geomechanical parameters carried out to determine optimum mud weight windows safe deviation trajectories using parameters. We propose a workflow equivalen...

a succession of late campanian- early maastrichtian is analyzed from gurpi formation with regard to the calcareous nannofossils. correlation matrix was applied for the first time to the entire nannofossil assemblage to reconstruct environmental conditions. a detailed quantitative calcareous nannofossil analyses is performed on samples in order to further investigate the climate events, and inte...
