METHOD AND SYSTEM OF USING A DATA WEIGHTED ELECTROMAGNETIC SOURCE FOR TIME-LAPSE MONITORING OF A RESERVOIR PRODUCTION OR HYDRAULIC FRACTURING

摘要

A system and a method for time lapse monitoring of a target feature within a rock formation are provided. The system includes a data weighted electromagnetic source configured to generate an electromagnetic field in vicinity or at a surface of the rock formation; and an electromagnetic receiver configured to measure a component of the electromagnetic field generated by the source. The data weighted electromagnetic source includes a plurality of electromagnetic sources and an electromagnetic field contribution from each electromagnetic source is weighted so as to enhance the component of the electromagnetic field measured by the electromagnetic receiver.
