Claim:
1. 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, the wellbore having a starting point at the earth's surface and a distal end point, wherein a drilling pipe may pass through the entire length of the well bore; inserting an abrasive cutting member into the well bore, wherein the abrasive cutting member comprises a wire rope comprising abrasive cutting surfaces; and tensioning the cutting member while the cutting member is drawn through the curved pathway; wherein the cutting member bears against the inside radius of the curved pathway and cuts an extended slot into the desired producing formation; and wherein the single well bore is in a substantially J-shape and extends from the surface, through the curved pathway, and ending as a blind hole at its distal end.
