Abstract:
Cement compositions comprising carboxylated inulin and methods of using the same to cement a workspace. In one embodiment, a method of cementing includes providing a cement composition comprising a carboxylated inulin, for example, in a subterranean formation. The method further includes allowing the cement composition to set. In some embodiments, the cement composition has a thickening time of from about 2 hours to about 11 hours. In other embodiments, the cement composition has a viscosity that is about constant for a period of time after the cement composition is placed.
