M019 INTERFERENCE ANALYSIS OF CEMENTED- PERMANENT-SENSOR DATA FROM A FIELD EXPERIMENT B. RAGHURAMAN and T. S. RAMAKRISHNAN Schlumberger Doll Research Old Quarry Road Ridgefield Connecticut 06877 USA Introduction 1 In 1999-2000 an oilfield experiment was conducted to test the application of electrical pressure and fiber optic measurement technologies to permanent reservoir monitoring. The principal objective of the experiment was to demonstrate the feasibility of monitoring water movement between an injection and observation well. Bryant et al. [1] describe results and interpretation of the cemented resistivity array data and show how the movement of the front could be tracked at the
