Abstract
A system for optimizing placement of a second wellbore relative to a first wellbore utilizing i) steam injected into the first wellbore in combination with a temperature sensor located in the second wellbore and ii) electromagnetic (EM) fields emanating from the first wellbore in combination with an EM sensor in the second wellbore. The magnetic measurements made with the EM sensor are utilized to determine azimuthal placement of a wellbore, while temperature measurements made with the temperature sensor are utilized to determine distance for placement of the wellbore.
