Systems, methods and apparatuses for monitoring and recovery of petroleum from earth formations
First Claim
1. A system for monitoring a location of a borehole for production of petroleum from an earth formation, the system comprising:
- an assembly including at least one of an injection conduit for injecting a thermal source into the formation and a production conduit for recovering material including the petroleum from the formation;
a guide conduit attached to at least a portion of the at least one of the injection conduit and the production conduit, the guide conduit extending in a direction at least substantially parallel to the at least one of the injection conduit and the production conduit; and
a detection source conduit insertable through the guide conduit and configured to dispose therein a detection source for detecting a location of the assembly in the formation, the detection source including an elongated electrically conductive member extendable along at least a portion of the detection source conduit, at least one portion of the elongated member including an electrosensitive material, the electrosensitive material reactive to an electric current to change shape in response to the electric current to form an electromagnet at the portion.

Abstract
A system for monitoring a location of a borehole for production of petroleum from an earth formation is provided. The system includes: an assembly including at least one of an injection conduit for injecting a thermal source into the formation and a production conduit for recovering material including the petroleum from the formation; a guide conduit attached to at least a portion of the at least one of the injection conduit and the production conduit, the guide conduit extending in a direction at least substantially parallel to the at least one of the injection conduit and the production conduit; and a detection source conduit insertable through the guide conduit and configured to dispose therein a detection source for detecting a location of the assembly in the formation. A method of monitoring a location of a borehole for production of petroleum from an earth formation is also provided.

15. A method of monitoring a location of a borehole for production of petroleum from an earth formation, the method comprising:
-
inserting a detection conduit through a guide conduit attached to at least a portion of at least one of an injection conduit and a production conduit in the borehole, the guide conduit extending in a direction at least substantially parallel to the at least one of the injection conduit and the production conduit; disposing at least one detection source in the borehole via the detection conduit, the at least one detection source including an elongated electrically conductive member extendable along at least a portion of the detection conduit, at least one portion of the elongated member including an electrosensitive material, the electrosensitive material reactive to an electric current to change a shape of the electrosensitive material; advancing the at least one detection source to a selected location; activating the at least one detection source to emit a detection signal by applying an electric current to the at least one detection source and causing the electrosensitive material to change shape in response to the electric current to form an electromagnet; and detecting the detection signal to determine a location of the detection source. - View Dependent Claims (16, 17, 18)
