Abstract
The present invention relates to a method and apparatus for obtaining measurements of induced resistivity of objects from confined spaces such as within the confined space of a down-hole hydrocarbon production well. It is well known that measuring the resistivity of an object or media can provide useful information regarding the composition and the location of object or media. The present invention utilizes the principles of Magnetic Antenna.TM. and Magnetic Lensing.TM. to obtain information regarding the location and properties of the target object.
