Abstract
The use of endless coiled tubing and nitrogen gas combine to offer efficient means of imitating and maintaining geothermal and reinjection well productivity. Routine applications include initial flashing of wells in addition to the surging of the formation by essentially the same means to increase production rates. Various tools can be attached to the tubing for down hole measurement purposes whereby the effectiveness of the tools is enhanced by this method of introduction to the well bore. Remedial work such as scale and fill removal can also be accomplished in an efficient manner by using the tubing as a work string and injecting various chemicals in conjunction with specialized tools to remedy down hole problems.
