Claim 11:
12. A fracturing fluid composition comprising;
a slurry comprising:
an oil-based vehicle comprising:
between 45% and 70% of a petroleum distillate,
between 1% and 5% of a suspending agent comprising a thermoplastic elastomer,
between 1% and 5% of a surfactant having a HLB value between 3 and 16, and
no white medicinal oil, and

a particulate water-soluble polyacrylamide comprising water-soluble polymer particles having particle sizes ranging between 75 mesh (200 μm) and 200 mesh (74 μm) and having molecular weights as low as 12 million,

a water source selected from the group consisting of fresh water, brackish water, salt water, sea water, produced water, flowback water, or combinations thereof, and
a proppant,, wherein:
the slurry is present in the fracturing fluid in an amount between 0.1 gpt and 0.5 gpt,
the oil-based vehicle coats the polyacrylamide particles reducing particle-to-particle cohesion,
the suspending agent suspends the coated polyacrylamide particles in the slurry reducing a rate of particle settling, and
the coated polyacrylamide particles cause the fracturing fluid to have a reduced rate of particle clumping or fish eye formation, to have an increased rate of particle hydration, to have a reduced value of fluid drag or friction caused by particle aggregation, and to have an improved proppant carrier capacity.
