A method of fracking a hydrocarbon-bearing formation using a crosslinked polymer gel, said method comprising the steps of:
- providing a hydrocarbon-bearing formation;
- providing a polymer;
- providing a cross-linking activator and adding such to the polymer;
- adding to the polymer mixture a caustic composition comprising:
- a caustic component;
- an additive adapted to provide an extended buffering effect to the caustic composition when such is exposed to acid;
- and
- water;
- adding a proppant to the resulting polymer mixture;
- and
- injecting said resulting polymer-proppant composition into the formation.
8 more elements
An aqueous caustic composition comprising:
- a caustic component;
- glycine;
- and
- water;
- wherein the caustic component is present in a concentration of up to 40 wt % of the composition and the caustic component and glycine are present in a molar ratio ranging from 15:1 to 5:1.
