3-D reservoir characterization and hydrocarbon volumetric estimation of parts of Niger Delta Basin-Nigeria

摘要: Abstract Coupled interpretation and modeling of seismic well log data, using geostatistical techniques was adopted to characterize reservoirs in a section the Niger Delta Basin. The study aimed at generating high resolution reservoir information such as spatial distribution petrophysical properties, subsurface structures (e.g., faults horizons) estimation hydrocarbon volume heterogeneous system. Five with over twenty fault were delineated. structural framework consists antithetic synthetic that influenced flow dynamics within field. Petrophysical properties estimated spatially distributed area via variogram statistics. Both sequential indicator Gaussian simulations performed transform pillar grids during process. Three realizations volumetrics obtained for each overall stock tank oil initially place field, show low outcome 245,720,570.40 barrels (STB) which indicates 90% probability exceeding quoted value, median 302,735,521.90 STB called reality-oriented model (i.e., 50% probability) 361,161,605.40 has 10% value. gas zone estimate low, outcomes 53,745.50, 56,487.60 60,618.50 million standard cubic feet (mmscf) respectively. Generally, results an integration data can yield geological plausible models enhance production management decisions complex systems.
