ABSTRACT:
The invention relates to cement compositions and methods of use for cementing oil and gas and/or geothermal wells which reduce thermal thinning of slurries at elevated downhole temperatures. To combat thermal thinning, latex is added to a cement slurry without a latex stabilizing surfactant resulting in a slurry having low mixing viscosity and good solids suspension properties at downhole temperatures.
