..., optimum slurry viscosities were observed at ambient temperature, thus avoiding pumping issues. Laboratory experiments showed that the fluid-loss control was excellent, but the viscosity of cement slurry was high at ambient temperature when the HM biopolymer was used as a FLA by itself. The addition of DCY...

..... The results are listed in TABLE 4 . First, when no Welan gum is present, a higher w/c ratio causes increased FLA adsorption, resulting in improved fluid loss control. Also, slurry rheology is decreased. TABLE 4 also demonstrates that at a w/c ratio of 0.7, the cement slurry possesses a very low yield point...
