Summary:
P327 MAPPING RESERVOIR BOUNDARY BY USING BOREHOLE-SURFACE TFEM TECHNIQUE: TWO CASE STUDIES Summary 1 The paper presents a borehole-surface Time-Frequency Electromagnetic (TFEM) method and its applications to reservoir boundary mapping. The method is used in the configuration that high power electromagnetic field is transmitted in borehole and secondary electromagnetic field is received on the ground. We study the target layer’s oil-bearing nature and delineate the reservior and its adjacencies by analyzing resistivity and difference of polarization phases. The results provide a reliable evidences for well network deployment during exploration and development phase and consequently improve efficiency of oilfield development. We
