LOW RESIDUE, HIGH SALINITY FRACTURING FLUIDS
Low residue, high salinity fracturing fluids may be produced by hydrating a gelling agent comprising carboxymethyl hydroxypropyl guar (CMHPG) in an aqueous fluid having a total dissolved solids concentration of about 30,000 ppm or greater and a pH of about 5 to about 8; adjusting the pH of the aqueo...

| description | Low residue, high salinity fracturing fluids may be produced by hydrating a gelling agent comprising carboxymethyl hydroxypropyl guar (CMHPG) in an aqueous fluid having a total dissolved solids concentration of about 30,000 ppm or greater and a pH of about 5 to about 8; adjusting the pH of the aqueous fluid to about 9 to about 10; and then, adding a zirconate crosslinker to the aqueous fluid to yield a crosslinked-CMHPG.
L'invention concerne des fluides de fracturation à forte salinité, faible résidu, pouvant être produits par l'hydratation d'un agent gélifiant comprenant un carboxyméthyl hydroxypropyl guar (CMHPG) dans un fluide aqueux ayant une concentration totale en solides dissous d'environ 30 000 ppm ou plus et un pH d'environ 5 à environ 8 ; l'ajustement du pH du fluide aqueux à environ 9 à environ 10 ; puis, l'ajout d'un agent de réticulation zirconate au fluide aqueux pour obtenir un CMHPG réticulé. |
