LOG BASED ENDPOINT SCALING IN RESERVOIR SIMULATION AND ITS INFLUENCE ON HISTORY MATCHING–CASE STUDY

Pages

Abstract

 THIS PAPER DESCRIBES A RESERVOIR SIMULATION BY MEANS OF LOG BASED ENDPOINTS AS IMPORTING DATA.THERE ARE SOME PROBLEMS IN USING CORE FLOODING EXPERIMENT DATA IN THE RESERVOIR. IT’S NOTEWORTHY THAT THE NUMBER OF CORE SAMPLES IS VERY LIMITED AND NOT EVERY ROCK TYPE HAS REPRESENTATIVE SAMPLE. ALSO SOME CORES ARE EXTRACTED WHICH ARE NOT SUITABLE FOR SOME SPECIFIC EXPERIMENTS SUCH AS WATER-OIL DISPLACEMENT EXPERIMENT. THEN IT WAS DECIDED TO USE PETROPHYSICAL LOGS TO DETERMINE END POINTS. FOR THIS PURPOSE AFTER DETERMINING THE TRANSITION ZONE OF THE RESERVOIR, IRREDUCIBLE WATER SATURATION MAP IS DEVELOPED. ALSO END POINTS IN CAPILLARY PRESSURE AND RELATIVE PERMEABILITY CURVES ARE GENERATED FROM WATER SATURATION AND POROSITY DATA OF LOG BY ATTENTION TO LITHOLOGY. FINALLY AFTER DEFINING ALL RELEVANT INPUT DATA TO THE SIMULATOR, THE RESERVOIR MODEL INITIALIZED SUCCESSFULLY AND HISTORY MATCHING PROCESS IS DONE.ACCEPTABLE HISTORY MATCHING SHOWS THAT DIFFERENT PARAMETERS TAKE THEIR MOST LIKELY VALUES IN THE MODEL.
