SYSTEM FOR CONDUCTING COMBINED SURFACE AND BOTTOM ELECTROMAGNETIC MEASUREMENTS AND METHOD FOR DETERMINING THE PROPERTIES OF PLASTIC FLUIDS

摘要

A method is proposed for monitoring a reservoir (12). The method includes performing the first set of electromagnetic measurements (30) at locations (22, 26) located on the surface of the earth, performing the first measurement with at least one sensor located in the well (18) near the reservoir, and determining the initial model (34) of the geological environment based on the first electromagnetic measurements and the first measurement of the sensor. The initial model of the geological environment includes the spatial distribution of the interfluid contact (15). At selected points in time (36, 34A) repeat the measurement of the sensor and electromagnetic measurements, and the results of repeated measurements determine (38) the spatial distribution of the interfluid contact.
