OPTIMIZATION OF IWAG INJECTION USING SEISMIC AMPLITUDE HOMOGENEITY - CASE STUDY

In this study, we used seismic stratigraphy mapping to optimize EOR wells through testing reservoir sand continuity and communication between injectors and producers. Grey Level Co-occurrence Matrix (GLCM) tool is used in the study to facilitate mapping of top and base of targeted sand in order to generate thickness maps, also the GLCM assisted in enhancing the homogeneous seismic amplitudes at the reservoir level which facilitated the mapping of reservoir sand. The final stratigraphic interpretation proposes a new geological model of sand distribution suggesting fluvial dominated delta. The new model is supported by the water cut rates at individual wells indicating that it is related to the sand quality. The study provided solid understanding of sand distribution at injection level, and this understanding is used to further optimize the injector wells locations and securing the project’s objectives
