MATERIALS FOR HYDRAULIC FRACTURE MAPPING

摘要

A method for hydraulic fracture mapping of a subterranean formation, the method comprising injecting into a wellbore a first fracturing fluid having a first magnetic and/or conductive material, injecting into the wellbore a second fracturing fluid having a second magnetic and/or conductive material and determining a location of at least one fracture having the first and the second magnetic and/or conductive materials therein using an instrument that is responsive to the first and the second magnetic and/or conductive materials. The first and the second magnetic and/or conductive materials have different material properties, concentrations, and/or shapes.
