ABSTRACT:
The invention relates to cement compositions for cementing wells, which allow pressure gas-channeling to be effectively controlled up to more than about 485.degree. F. The cement composition contains a styrene-butadiene latex and a stabilizer. The film of latex interrupts gas-channeling after an extremely brief path.
