PARALLEL FED WELL ANTENNA ARRAY FOR INCREASED HEAVY OIL RECOVERY

摘要

A parallel fed well antenna array and method for heating a hydrocarbon formation is disclosed. An aspect of at least one embodiment is a parallel fed well antenna array. It includes an electrically conductive pipe having radiating segments and insulator segments. It also includes a two conductor shielded electrical cable where the shield has discontinuities such that the first conductor and the second conductor are exposed. The first conductor is electrically connected to the conductive pipe and the second conductor is electrically connected to the shield of the electrical cable just beyond an insulator segment of the conductive well pipe A radio frequency source is configured to apply a signal to the electrical cable.
