| titleOfInvention |
An improved composition for a lightweight cement slurry for cementing oil and gas wells |
| abstract |
A lightweight cement slurry composition having a density in the range of 1.2 to 1.6, containing a solid extender agent and an SBR latex. The ratio of the liquid volume to the slurry volume should be less than 70% and preferably less than 63%. The lightweight slurry then presents a most attractive set of properties which could not be obtained previously, and in particular gas channelling is controlled. |
