SHmax orientation derived from borehole breakouts coincide well with the result from the FMS in the collision zones of the Kuqa Depression. Fractures were evaluated by core-image integration and could increase formation permeability with 1-3 order of magnitudes. The MGPI index was used for hydraulic evaluation of open fractures.
