HYBRE-110  is  an  oil-based  slurry  used  as  a  breaker  for  gelled  hydrocarbons.  It  is effective  at  temperatures   ranging  from  40°F  to  300°F.

GEBRE-111L  is a highly concentrated, moderate  pH  liquid  enzyme  breaker  for  fracturing  fluids. GEBRE-111L gives clean,  reproducible  breaks  in  guar  and  modified  guar  gels  at  pHs  in  the  range  of  about  4  to  8.

GEBRE-112P  is a conventional, m oderate pH  enzyme  breaker  for  fracturing  fluids.  It  is  packaged  with  a   calibrated  scoop  in  each container  for  easy  measurement  in  the  field.  GEBRE-112P  gives  clean,  reproducible   breaks  in  guar  and  modified  guar  gels  to  pHs  as high as  about 8

GEBRE-114L  is  a  liquid  enzyme  breaker designed  specifically  for  use  in  borate- crosslinked  fracturing  gels  at   pH’s as high as 10.  It  gives  clean,  reproducible breaks at  temperatures from 70°F  to  at  least  140°F.

GEBRE-115L  is  a  liquid  enzyme  breaker designed  specifically  for  use  in  borate-crosslinked  fracturing  gels  at   pH  as  high  as  10. It  gives  clean,  reproducible  breaks  at  temperatures from 100°F to at least 170°F.

GEBRE-116L  is  a  liquid  chlorite  based  breaker  designed  specifically  for  use  in  borate-  crosslinked   fracturing  fluids.  It  gives  clean,  reproducible  breaks  on  both  the  frac  fluid  and  filter  cake  at  temperatures greater  than  200°F.  Due  to  the  removal  of  filter  cake  higher  regained permabilities can often be attained than  conventional  oxidants  can  give.

GEBRE-LT  is  an  encapsulated  persulfate  breaker  for  fracturing  fluids.    It  gives  delayed  breaks  at  moderate   tem peratures  relative  to  uncoated  persulfate. GEBRE LT  can  be  used  in  low  viscosity  crosslinked  guar   fluids  at  temperatures  where  uncoated  persulfate  results  in  very  quick  breaks.

GEBRE-HT  is  an  encapsulated  persulfate breaker  for  fracturing  fluids.  It  gives  delayed  breaks  relative  to   uncoated  ammonium  persulfate  and  so  can  be  used  at  higher  temperatures.

GEBRE-HTC  is  a  preslurried  form  of  a high  temp  oxidizing  breaker  for  guar  based fracturing  fluids.  It  is  an   effective  breaker  at temperatures  from  220°F  to  280°F.

GEBRE-117  is  an  oxidizing  breaker  that destroys  the  polyacrylamide  polymers used in slickwater fracturing  treatm ents.  It  can  be  added  directly  to  these  frac  fluids  and  does not interfere with  their  friction  reduction,  but   degrades the polymers  within  hours.  Patent  protection  has  been  applied  for  on  this  technology.

Sodium  Persulfate  is  an  oxidative  breaker  for fracturing  fluids  at  low  to  moderate  temperatures.  It  is  often  preferred  to ammonium  persulfate  as  it  “clumps”  much  less in  storage.

GEBRE-118  is  an  encapsulated  sodium  bromate  breaker  for  fracturing  fluids.  It  gives  delayed  breaks   relative to uncoated  bromates  and  so  can  be  used  at  higher  temperatures.
