Method and apparatus for increasing well productivity

A method for increasing well productivity in a desired producing formation, comprising:

• forming a single well bore having a substantially curved path at least within the producing formation, the wellbore having a starting point at the earth's surface and a distal end point;
• attaching an abrasive cable to a drill pipe;
• extending the drill pipe from the surface to at least near the curved path, wherein the attached abrasive cable extends at least through a portion of the curved path
• reciprocating the pipe within the wellbore to produce a sawing action with the abrasive cable and cut an extended slot along the inside radius of the curved path extending away from said wellbore;
• and
• tensioning the attached abrasive cable such that the abrasive cable is urged laterally.

A method for increasing well productivity in a desired producing formation, comprising:

• drilling a single well bore along a curved pathway through the desired producing formation, wherein the single well bore is in a substantially U-shape and extends from the surface, through the curved pathway, and back to the surface, wherein a drilling pipe may pass through the entire length of the well bore;
• extending a tubing pipe from each end of the well bore to the curved pathway;
• inserting an abrasive cutting member into the well bore, wherein the abrasive cutting member comprises a wire rope comprising abrasive cutting surfaces, wherein the abrasive cutting member passes through and is attached to each tubing pipe;
• and
• pulling on each of the tubing pipes in an alternating manner to draw the abrasive cutting member through the curved pathway to cut the extended slot.
