FHF with selective packer

Selective packer allows to stimulate different intervals in one well via FHF method selectively and repeatedly, changing the unit location. Major advantages of the selective packer: No need for performing an underground equipment round-tripping after each FHF stage with packer and anchor equipment replacement; No need to repeatedly attract geophysical party for well-blasting operations (WBO) - perforation is performed at one perforated lot delivery; Packer setting geophysics costs cutout (unified access for all FHF stages); No need in sand bridges back filling after each (except for the last) FHF stage; Absence of wellbore clean out from sand bridges after multiple-stage FHF; Frac spread relocation costs cutout.
