Abstract

See full text

Method and apparatus to determine the relative and/or absolute position of a phase change in a fluid reservoir comprising hydrocarbons by providing a first wire in a borehole within the reservoir; providing a reference system to the first wire in the borehole; transmitting an electromagnetic signal through the first wire; detecting a detected response to the electromagnetic signal from the first wire; generating a reference response from the reference system; using the reference response to correct the detected response; and determining the phase change position using data from the corrected response. Reference systems in the form of a second wire; a transmission line and an electronic equivalent circuit simulation model; and an electrical model of the first wire and borehole, are described.
