BF-121 is a freeze-protected mixture containing an acetic  anhydride  and  salt.  It  is  a  pH  control  agent  for  CMHPG   polym er  hydration  also  used  as  a  pH  control  in  low  pH  CMHPG  system.

BF-122  is  a  pH  control  agent  for  high-pH fracturing  fluids.  It  is  useful  in  both  borate-  and  zirconium-   crosslinked  fluids,  particularly at high temperatures  where  a  pH  of  10  or  higher  is  required  for  gel  stability.

BF-123  is  a  pH  control  agent  for  high-pH fracturing  fluids.  It  is  useful  in  both  borate-  and  zirconium-   crosslinked  fluids,  particularly  at  high temperatures  where  a  pH  of  10.5  or  higher  is  required  for  gel  stability.

BF-123W  is  a  pH  control  agent  for  high-pH fracturing  fluids.  It  is  a  winterized  version  of  BF-123  with  a  free   point  of  -38°F that may require  slightly  higher  loadings  than BF-123. It  is  useful  in  both  borate-  and  zirconium-  crosslinked  fluids,  particularly  at  high temperatures  where  a  pH  of  10.5  or  higher  is required for gel stability.

Plexaid  TDS  is  a  patent  pending  fracturing  fluid additive  that  is  a  component  used  in  crosslinking  produced  water,   processed  produced  water,  or flow-back  water  –  any  water  containing  high concentrations  of  total  dissolved  solids   (TDS)  – with    a    guar    polymer    and    boron    crosslinker.  Plexaid    TDS    mitigates    the    formation    of    calcium,     magnesium  and  other  dissolved  solids’ precipitates  that  are   produced   when   common  buffering   agents   such   as    sodium   hydroxide  (caustic)   and   potassium   hydroxide  (KOH)  are used  in  waters  containing  high  levels  of  total  dissolved   solids.

Potassium  Carbonate  is  a  buffer  for  high  pH zirconium  and  borate  crosslinked  fracturing  fluids.  It  economically   reaches useful pH values with  low  tendency  to  “overshoot”  to  high  pHs.
