Grid and Streamline Models: Comparative Study Related to the Production History ofFractured Carbonate Reservoir

摘要

The Upper Devonian carbonate reservoir characterization ofrnthe Pamyatno-Sasovskoe Oilfield, Volgograd Region, Russia,rnis based on geological data, geophysical log, hydrodynamicrnand tracer investigations. The reservoir model based onrngeostatistical techniques with grid blocks has been used tornupdate a flow simulation to available data on productionrnhistory. The reliability of this reservoir model is lower becausernof the match to available data is unacceptable. The method tornmodel permeability on the coarse scale presents therncombination of the borehole radon indication and tracerrninvestigation. According to tracing results, a streamline-basedrnmodel is to be most realistic, gives a basis to propose thernparameters and properties of streamlines and to predict thernwater-cut process.
