FECH-32  is  a  chelating  agent  for  use  in controlling  iron  precipitates  in  some  oilfield  applications.  It  also  can  be   used in certain scale- removal applications where  acidizing is not practical.

FECH-33  is  a  chelating  agent  for  the  control of  iron  precipitation,  particularly  in sandstone  acidizing. FECH-33  is  effective  at temperatures  as high as 350°F, and contains  no components known to cause secondary  precipitation  in  hydrofluoric  acid treatments.

FECH-34  is a powerful iron reducing agent for  hydrochloric  acids  of  any  strength.  It  is  used  primarily  to   help control iron-induced  sludging in acids such as 28%  hydrochloric

FEC-36  is  an  iron  control  agent  designed  to help  retain  iron  com pounds  in  spent  acid after   oilwell  acidizing  treatments.

FEC-3-28  is  a  complete  iron  control  system  for  acidizing  in  any  strength  of  acid  including  28%   hydrochloric.  A  U.S.  P atent  has  been  applied  for  on  this  new  technology  to  minimize  iron-induced  sludging  and  iron   precipitates  in  any  oilwell  acidizing

FER-37  is  a  com plete  iron  control  system  for  oil well  acidizing.  This  patented  product uses  field-proven   technology  to  minimize  iron-induced  sludging  and  precipitation problems  in  all  types of  acidizing.

WFA-38  is  an  oxidizing  agent  that  is particularly  suitable  for  destroying  hydrogen sulfide and  iron  sulfide  in   oilfield  water-handling systems.

The  Reducer™  is  a  complete  iron  control  system  for  oil  well  acidizing.  This  patented product  uses  field-proven   technology  to  minimize  iron-induced  sludging  and precipitation problems in all  types  of  acidizing.
