Acidgen FG3 is a liquid acid precursor that is dissolved in fresh water, seawater or completion brine together with other ORCA for WBM chemicals to produce treatment fluids for water based mud damage or acidizing carbonate formations. Ideally the ph of the base brine should be in the range of 6 – 8 before adding Acidgen FG3. The rate of acid production from Acidgen FG3 may be accelerated down hole by including one of the following catalysts in the fluid formulation: C55 Enzyme or CS – GBC – 1.
