Claims21
A method comprising:
- contacting subterranean shale with a treatment fluid,
- wherein the treatment fluid comprises (i) a biopolymer comprising a hydroxyethyl cellulose (HEC), (ii) a polyamine comprising a hexamethylene diamine (HMD), and (iii) an aqueous base fluid, and
- wherein the treatment fluid comprising the HEC and HMD increases a recovery of one or more drill cuttings by at least about 15% as compared to a treatment fluid comprising the HEC and absent the HMD.
A method comprising:
- contacting (i) a biopolymer comprising a hydroxyethyl cellulose (HEC), (ii) a diamine comprising a hexamethylene diamine (HMD), and (iii) an aqueous base fluid to form a treatment fluid;
- and
- placing the treatment fluid into a wellbore penetrating a subterranean shale formation,
- wherein the treatment fluid comprising the HEC and HMD increases a recovery of one or more drill cuttings by at least about 15% as compared to a treatment fluid comprising the HEC and absent the HMD.
