Geothermal Well Stimulation Using Water Jet Cutting in Mexico

When a geothermal well needs to be stimulated due to low permeability in the reservoir, the first solutions usually proposed are the acidizing and fracturing with hydraulic or thermal methods. All these techniques have been proved worldwide with acceptable results but sometimes with high cost or sophisticated equipment and procedures. In this paper the water jet well stimulation technique for geothermal application is described. This technique is extensively used for downhole mining and has demonstrated excellent results in reservoir enhancing in Mexico with an easy implementation and competitive cost.
