发明名称 FERROFLUID TOOL FOR INFLUENCING ELECTRICALLY CONDUCTIVE PATHS IN A WELLBORE
摘要 A tool for influencing electrically conductive paths using ferrofluids in a downhole system is provided. The downhole system can include a tool body, a source of ferrofluid, and a magnet. The magnet can provide a magnetic field that influences an electrically conductive path within an annulus between the tool body and a wellbore formation by arranging the ferrofluid from the source in the annulus.
