1. A cement slurry comprising:
graphene, wherein the graphene comprises bioderived renewable graphene (BRG), wherein the BRG comprises nanosheets comprising greater than 90 weight percent carbon, and wherein the nanosheets have a surface area of at least 2000 m2/g and up to 2496 m2/g, a pore volume of at least 3 cc/g and up to 5.0 cc/g, or a combination thereof;
a cement; and
water,
wherein the cement slurry is positioned in a wellbore and the cement slurry, when unset, has reduced transient gel formation relative to a same cement slurry, when unset, absent the graphene.
