Evaluation of Quantitative Criteria for Triassic Reservoirs in the South Mangyshlak Basin

چکیده
Carbonate rocks of the Triassic deposits South Mangyshlak basin are investigated in this paper for their boundary values, which important interpretation field geophysical data as well perforation and blasting. Based on lithological composition, classified either terrigenous or carbonate reservoirs. reservoirs found Middle strata containing volcanogenic dolomite limestone rocks. A complex type reservoir characterizes these rocks: porous-fractured, porous-cavernous, fractured. Upper sediments formed by intercalation tuffaceous, siltstone-sandy, mudstone overlying sedimentary Oil confined to polymictic sandstones, oil-saturated varying degrees. In order substantiate quantitative criteria reservoir, experimental studies core samples were carried out laboratory. Fluid flow performed where physical hydrodynamic characteristics determined when oil was displaced displacing reagents. On basis parameters obtained, correlations between non-reservoirs constructed. relationships properties such porosity permeability versus residual water content, effective dynamic porosity, values determined. Using results, limit has been be 7%, 0.02 X 10-3 μm2, 0.3 μm2.

Quantitative assessment of relative tectonic activity in the Alamarvdasht river basin, south of Iran
Tectonic processes are major factors controlling landform development in tectonically active areas. In order to evaluate quantitative measurement of tectonic activities in the Alamarvdasht basin in the south of Iran, six different morphological indices including stream-gradient index (SL), drainage basin asymmetry (Af), hypsometric integral (Hi), valley floor width-valley height ratio (Vf), dra...
