A Geostatistical Study of Rock Permeability in a Multi-Layer Carbonate Oil Reservoir

In this work spatial distribution of rock permeability in one of the Iranian south western multi-layer carbonate oil reservoirs is studied using geostatistical techniques. Input data were obtained from welltestingoutputs. To do this, transient pressure data from 28 wells in this reservoir were interpreted andpermeability at different locations within the reservoir was determined. Using these data, high permeability layers were identified. Then to estimate spatial distribution of rock permeability all aroundthe reservoir, Kriging techniques were applied and iso-permeability curves were generated. Main geostatitcal results will be discussed in paper in details
