Geochemical Characteristics and Hydrocarbon Generation Modelling of Early Triassic to Late Cretaceous Formations within Ogaden Basin, Ethiopia
The major goal of this study is the evaluation of the source rock of Ogaden Basin using Rock-Eval Pyrolysis, Vitrinite reflectance (%Ro), and well log data of the Permo-Triassic and the Mesozoic sequences including Karro, Hamanlei, and Urandab Formations. Burial history and level of thermal maturity of the Bodle-1 well, the Calub-1 well and the Hilala-2 well were modeled based on the calibratio...
متن کاملgeochemical and prtrographical study of dolomite facies in the dalan and kangan gas reservoirs in the south of iran
in carbonate systems, dolomites often form the best reservoirs .the dolomitized part of dalan(upper permian) and kangan(lower triassic) formations makes up the essential part of gas reservoirs in the south of iran. the dalan and kangan formations were dolomitized to various degrees in the areas of south of iran and- persian gulf.in most cases, dolomitization enhanced porosity and permeability o...
متن کاملTectonosedimentary evolution of the basins in Central Alborz, Iran
Evidence of at least ten different tectonic- controlled sedimentary basins can be recognized in the central part of the Alborz Mountains in the Middle part of the Alpine-Himalayan belt. They formed from Neoprotrozoic to recent time as the results of the relative plate motion in southwest of Asia in Tethyan realm. The basins include: (1) Prototethys Late Neo-Proterozoic to Early Ordovician epi-c...
متن کاملPetrographic Characteristics and Fluid Inclusion Study of Carbonate Cements in Permian-Triassic Rock Sequence of Southern Iran: an Implication of Rock-fluid Interactions in Carbonate Reservoir Rocks
The study of the carbonate cements in the Permian-Triassic Dalan-Kangan formations resulted in the identification of five stages of calcite and dolomite cementation, which completely or partially occluded pores. Cement types appear to be early isopachous calcite (i; C1-non-luminescence), equant (ii; C2-dull CL), fairly coarse secondary dolomite rhombs (iii; C3-zoning red CL), coarse sparry calc...
متن کاملMilankovitch climatic signals in Lower Triassic (Olenekian) peritidal carbonate successions, Nanpanjiang Basin, South China
Meter-scale peritidal carbonate strata from an isolated platform in the Nanpanjiang Basin of South China were tested for the presence of periodic or quasi-periodic climatic signals. These signals provide information on factors controlling cyclic sedimentation in the equatorial eastern Tethys during the Early Triassic greenhouse period. Parasequences are composed of shallowing-upward successions...
