Abstract

Disclosed is a concentrate composition for crosslinking polysaccharide polymers hydrated in an aqueous liquid, and well servicing fluids, preferably fracturing fluids, prepared therewith. Preferred polysaccharide polymers are galactomannan gums or derivatives thereof, preferably hydroxypropylguar. The concentrate comprises an alkali metal formate solution, preferably potassium formate, a crosslinking agent for the polysaccharide polymer. preferably ai sparingly soluble alkali metal car alkali metal alkaline earth metal borate, wand d suspension agent, preferably a clay mineral selected from the group consisting of smectitc clays, palygorskite clays, and mixtures thereof. Exemplary clays are hectorite, sepiolite, and attapulgite. The concentrate may, optionally, contain a deflocculant and/or an anti-syneresis additive.

Claims (11)

1. A concentrate for the crosslinking of polymers in aqueous solutions which comprises an alkali metal formate solution, a crosslinking agent suspended therein, and a suspension agent.
2. The concentrate of claim 1 wherein the concentrate is pourable or, if gelled, exhibits fragile gels such that the concentrate is pourable upon gentle agitation or low shear mixing.
3. The concentrate of claim 2 wherein the alkali metal formate solution is a potassium formate solution having a density of at least about 9.5 pounds per gallon.
4. The concentrate of claim 3 wherein the crosslinking agent is a sparingly soluble alkali metal or alkali metal alkaline earth metal borate in an amount from about 100 to about 250 pounds per 42 gallon barrel of the concentrate.
5. The concentrate of claim 4 wherein the suspension agent is a clay mineral selected from the group consisting of smeetitc clays, palygorskite clays, and mixtures thereof; in an amount from about 2 to about 15 pounds per 42 gallon barrel of the concentrate.
6. The concentrate of claim 4 wherein the suspension agent is a clay selected from the group consisting of hectorite, sepiolite, attapulgite, and mixtures thereof.
7. The concentrate of claim 6 which contains from abut 0.5 to about 6 pounds per 42 gallon barrel of the concentrate of a deflocculant.
8. The concentrate of claim 7 which contains an anti-syncrosis agent.
9. A well servicing fluid comprising an aqueous liquid having hydrated therein a galactomannan gum or derivative thereof the gum being crosslinked with the concentrate of claim 1, 2, 3, 4, 9, 6, 7, or 8.
10. A fracturing fluid comprising an aqueous liquid having hydrated therein a galactomannan gum or derivative thereof, the gum being crosslinked with the concentrate of claim 1, 2, 3, 4, 5, 6, 7, or 8.
11. A method of preparing a formate-containing fracturing fluid which comprises hydrating a galactomannan gum or derivative thereof in an aqueous liquid and thereafter crosslinking the galactomannan gum with the concentrate of claim 1, 2, 3, 4, 5, 6, 7, or 8.
