Cement Retarder #3

Other Names: GCR 3, Mid-Temperature Cement Retarder
Basic Properties: Cement Slurry Retarder, Thickening Time Extender, Set Time Controller
As a cement slurry retarder, Cement Retarder #3 is utilized in oil and gas well cementing operations to delay the setting time of cement slurries, ensuring sufficient time for proper placement, especially in wells with higher bottomhole temperatures. This additive is particularly effective in mid-temperature environments, with an optimum temperature range of 140?F (60?C) to 230?F (110?C).
The normal concentration of Cement Retarder #3 varies between 0.15% to 1.0% by weight of cement (BWOC), depending on the specific requirements of the cementing operation and the anticipated downhole temperatures. citeturn0search5
By incorporating Cement Retarder #3 into the cement slurry, operators can achieve improved placement and bonding of the cement sheath, enhancing the overall integrity and longevity of the wellbore.
pH: Specific pH information for Cement Retarder #3 is not provided in the available sources. However, cement retarders are generally designed to be compatible with standard cement slurry formulations and do not significantly alter the pH of the mixture.
