Characterization and geostatistical modeling of reservoirs in ‘Falad’ field, Niger Delta, Nigeria

Abstract This research aims at characterizing and modeling delineated reservoirs in ‘Falad’ Field, Niger Delta, Nigeria, to mitigate the challenge caused by heterogeneous nature of reservoirs. Seismic well log data were integrated, geostatistics was applied describe reservoir properties interwell spaces within study area. Four reservoirs, namely RES 1, 2, 3 4, correlated across four wells. The {lithology, net gross, porosity, permeability, water saturation} all mapped determined, two with best quality picked for further analysis (surface generation modeling) after ranking based on their quality. Structural interpretation field carried, nine faults (F1—F9), fault polygon generated. structural model showed area is structurally controlled major (F1 F3) oriented SW–NE direction while other one (F4) NW–SE direction. A 3D grid constructed using surfaces distributed stochastically simple krigging method sequential Gaussian simulation, indicator simulation random function algorithms. Geostatistical used this has been able give subsurface information areas deficient as estimated gotten from existing wells have spatially will thus aid future development also they are identifying new prospect combining property models maps
