Earth Pro Hotset Cement is a thermally stable cement blend package designed specifically for use in wireline operations. It contains a combination of several additives developed to keep the cement slurry stable and in fluid form for the placement time necessary to set deep plugs at temperature extremes from 100 – 130°C. Thermal cement is typically used where wellbore temperatures exceed 100°C, due to well depth, or physical treatment (i.e., steam flooding, etc.).
Under these conditions, normal Class G cement undergoes severe and detrimental chemical structure changes causing a rapid breakdown of cement integrity leading to plug failure. Earth Pro Hotset Cement overcomes this degradation by the increased loading of silica (SiO2), which extends the product stability to the temperatures described herein and beyond.
