| titleOfInvention | Fracturing or gravel-packing fluid with CMHEC in brine |
| abstract | A method of treating a treatment zone of a subterranean formation penetrated by a wellbore of a well, the method including the steps of: (A) forming a treatment fluid comprising: (i) an aqueous phase comprising water having at least 1,000 ppm total dissolved inorganic salts; (ii) a carboxymethyl hydroxyethyl cellulose, wherein: (a) the carboxymethyl hydroxyethyl cellulose has a carboxymethyl degree of substitution is in the range of about 0.3 to about 0.45 per glucopyranose unit in the polymer; and (b) the carboxymethyl hydroxyethyl cellulose has a hydroxyethyl molecular substitution is in the range of about 2.1 to about 2.8 per glucopyranose unit in the polymer; and (iii) a breaker for the carboxymethyl hydroxyethyl cellulose; and (B) introducing the treatment fluid into the treatment zone. In embodiments, the carboxymethyl hydroxyethyl cellulose may or may not be crosslinked. |
