If you did not include a short abstract for the online version whenyou submitted the manuscript, the first paragraph or the first 10 lines of the chapter will be displayed here.If possible, please provide us with an informative abstract.Oilwell cements are slurries that fill the annular space between the borehole and the steel casing in oilperforation. These cements must have special features to achieve many properties that are of demand of afluid that flows at high pressures, high temperatures, and great depths. These features are achieved with theuse of polymers, named as additives or admixtures in the construction materials industry. In this chapter,some of the admixtures based on renewable biomass products are described. Some of these are celluloseethers, used as fluid loss agents; lignosulfonates, used as dispersants, xanthan, and welan gum and othermicrobial polysaccharides, mainly used as a viscosity modifiers, and micro- and nanocellulose fibers, whichare used as loss circulation agents.
