1. A slurry composition comprising:
a base oil;
a nonionic surfactant;
a hydrophilic polymer; and
a mixed branched organoclay composition comprising: a phyllosilicate clay; and a mixture of quaternary ammonium ions, each ion having a formula of [N—R1R2R3R4]+ wherein, within such mixture of quaternary ammonium ions, one or more of R1, R2 and R3 is each a mixture of branched alkyl groups, each branched alkyl group having 12 to 22 total carbon atoms, a linear backbone and one or more C1 to C3 branching alkyl groups each attached to the linear backbone at a branching carbon position, and within each quaternary ammonium ion and within the mixture of branched alkyl groups, the C1 to C3 branching alkyl groups are linked to the linear backbones at different branching carbon positions as a distribution; and wherein when one or more of R2 and R3 is not a branched alkyl group, one or more of R2 and R3 are a first linear alkyl group having 1 to 22 carbon atoms, wherein R4 is selected from the group consisting of a second linear alkyl group having 1 to 6 carbon atoms, an aryl group, and combinations thereof, and
wherein the hydrophilic polymer is selected from the group consisting of polyacrylamide, guar, hydroxypropyl guar, hydrophobically modified hydroxypropyl guar, carboxymethyl guar, carboxymethyl hydroxypropyl guar, glactomannan gums, derivatized guars, xanthan gum, starch, derivatized starches, saccharides, xanthan, derivatized xanthan and mixtures thereof.
