Evaluation of the Quantitative Criteria of Triassic Carbonate Rocks Reservoirs
Author(s): Sudad H Al-Obaidi* and Wj Chang
South Mangyshlak basin is investigated in this paper. The Triassic deposits of carbonate rocks are investigated in this paper for their boundary values. These values are important for the interpretation of field geophysical data, as well as for perforation and blasting.
Triassic deposits, due to their lithological composition, are classified as either terrigenous or carbonate reservoirs. Carbonate reservoirs are found in the Middle Triassic strata containing volcanogenic dolomite and volcanogenic limestone rocks. These rocks create a complex type of reservoir that is characterized as porous-fractured, porouscavernous, and fractured. The intercalation of tuffaceous, siltstone-sandy, and mudstone rocks create the Upper Triassic sediments which overlie Middle Triassic sedimentary rocks. Oil deposits are confined to polymictic sandstones, which are saturated with oil to varying .. View More»
