Abstract
A method is disclosed for monitoring a reservoir. The method includes making a first set of electromagnetic measurements at locations along the Earth's surface, making a first measurement from at least one sensor disposed proximate the reservoir in a wellbore and determining an initial Earth model from the first electromagnetic and first sensor measurements. The initial Earth model include a fluid contact. At selected times, the sensor and electromagnetic measurements are repeated and a spatial distribution of the fluid contact is determined from the repeated measurements.
