Y R. VANN "CONTINUOUS BOREHOLE FORMED HORIZONTALLY THROUGH A HYDROCARBON PRODUCING FORMATION" ABSTRACT OF THE INVENTION A borehole is formed down into the ground and extends towards an underlying pay zone, and then is turned horizontally through the pay zone, and then continues back up towards the sur- face of the earth; so that the resultant borehole is continuous from an inlet to an outlet, with the inlet and outlet being spaced from one another. When the free end of the drill string arrives at the outlet, one end of a casing string is attached thereto, and the casing string is pulled back through the entire borehole so that the borehole is cased from the outlet to the inlet, or vice versa. The casing is perforated adjacent to the pay zone so that the hydrocarbons may flow from the pay zone into the interior of the casing. Production is achieved through either of the spaced inlet or outlet; or, by using one vertical length of the borehole to force fluid to flow through the entire borehole, thereby forc- ing the production to the surface. - 1 -
