1. A method to extract oil from the ground, comprising the steps of
(a) providing an oil extraction apparatus comprising an elongate tubular assembly, said assembly comprising
(i) a plurality of sequential interconnected units each including
a hollow cylindrical conduit having
a first end,a second end,a first gear mounted at said first end,a second gear mounted at said second end,a drive shaft connected to said first and second gears and extending through said conduit and intermediate said first and second gears,at least one helical blade attached to and extending about said drive shaft,said first gear on a first one of said sequential units engaging said second gear on a second one of said units adjacent to said first one of said units to interconnect said first and second units such that
when said drive shaft in said first one of said units rotates, said drive shaft in said first one of said units rotates simultaneously with said drive shaft in said second one of said units, andwhen said first gear rotates, said second gear rotates simultaneously with said first gear,(ii) operable motive power to rotate said interconnected units,(iii) an electrically conductive coil-magnet assembly operatively associated with a selected one of said plurality of units such that
rotation of said selected one of said plurality of units inductively produces an electromotive force across said coil and produces eddy currents in at least one in a group consisting of said coil and said selected one of said plurality of units,the eddy currents generate heat in at least said selected one of said plurality of units,said electromotive force travels along at least a portion of said selected one of said plurality of units and generates heat in said selected one of said plurality of units; (b) boring an elongate canted opening in the ground at a selected angle from the ground, said opening extending from the surface of the ground to a subterranean space in which oil resides; (c) inserting said oil extraction apparatus in the bore such that a portion of said first one of said units is positioned to receive oil from said subterranean space; and, (d) operating said motive power to rotate said units such that
(i) oil from said subterranean space travels up said first and second ones of said units, and(ii) said electrically conductive coil-magnet assembly produces an electromotive force across said coil and generates heat in at least said selected one of said plurality of units. |
