Cementing solutions designed for stability in high temperature geothermal wells
Talk to an expertGeothermal energy is harnessed from the heat produced and stored deep within the earth's core. Because geothermal heat is continuously produced naturally, it is both a renewable and low carbon footprint energy source. Geothermal wells are often drilled into high temperature reservoirs, which require cementing solutions that can be placed at elevated temperatures. Geothermal environments may contain highly corrosive fluids, which can lead to degradation of the cement sheath and tubulars over time. Halliburton understands the complexities of geothermal resource development and can provide innovative, tailored technologies to address the range of challenges cementing in a geothermal environment requires.
Lightweight slurry designs that can be placed via our ZoneSeal® process across weak, highly fractured formations to prevent cement fall back and lost circulation. Reduced Portland cement designs and non-Portland solutions, such as the ThermaLock product portfolio, can be foamed to provide superior insulation properties and long-term chemical resistance.
ThermaLock™ cement is a non-Portland, low permeability barrier system that is nonreactive with CO₂ and is ideal for ultrahigh-temperature applications.
