According to the invention, a process and system are disclosed for conditioning an oil or gas formation and the application of the various stimulating fluids to the oil or gas formation. The method consists of drilling from a vertical well hole a horizontal spiralling hole which spirals out into the oil or gas formation and around the vertical well hole. Other embodiments include the drilling of a horizontal inward spiralling well from a vertical well hole that inwardly spirals out into the oil or gas formation from the vertical well hole, and the drilling of a hole from a vertical well hole that spirals out and coils down through an oil or gas formation around the vertical well hole. The application of this process is contingent on the use of my remote control directional drilling system, U.S. Pat. No. 3,811,519, and my flexible drill pipe pending application Ser. No. 465,500, filed Apr. 30, 1974 on related equipment, now abandoned.
