Abstract
A system for production of petroleum from an earth formation. The system includes: an injection assembly disposable within a first borehole for injecting a thermal source into the formation, the injection assembly including an injector extending from a distal end of the assembly; and a production assembly disposal within a second borehole for recovering material including the petroleum from the formation, the production assembly including a collector extending from a distal end of the assembly. At least one of the injector and the collector includes at least a first conduit and at least a second conduit concentric with the first conduit, the first conduit having a first distal end and the second conduit having a second distal end, the first and second distal ends located at different locations along a length of at least one of the first and second borehole.
