so zn has apparently been doing a matrix acid job-a small acid stimulation- not a high pressure acid stimulation-and has been recovering remaining acid in the completion fluid
so that type of micro fracking employed by zn does not have the same environmental concerns as regular fracking
plus zn location is not as sensitive as the golan either geopolitically nor environmentally- golan plus mt herman etc produces much of israels water- meggido valley does not-and zn is within the pre-1967 borders
A matrix acid job is performed when acid is pumped into the well and into the pores of the reservoir rocks. In this form of acidization, the acids dissolve the sediments and mud solids that are inhibiting the permeability of the rock, enlarging the natural pores of the reservoir and stimulating flow of hydrocarbons.
While matrix acidizing is done at a low enough pressure to keep from fracturing the reservoir rock, fracture acidizing involves pumping highly pressurized acid into the well, physically fracturing the reservoir rock and dissolving the permeability inhibitive sediments
