Abstract

A media displacement device has a body configured to be positioned radially outwards of a tool having an antenna for transmitting electromagnetic energy to or receiving electromagnetic energy from an earth formation. The body is made of materials causing less power loss to electromagnetic energy transmitted or received by the tool than the media the body is configured to displace.
