Grouting with Graphite for Geothermal Drilling

Geothermal energy is a renewable energy source as heat is continuously produced inside the earth. Not dependent on weather condition and displaying high-capacity factors, geothermal coils can supply base load energy for both heating & cooling and is one of the most consistent forms of renewable energy.  Because of these features, many developments (such as Edmonton’s Blatchford community) are now building on Geothermal energy. Learn more about Geothermal energy through IRENA. Rice Earth Sciences can supply Geothermal drilling needs, working with key manufacturers such as Baroid Industrial Drilling Products & CETCO.  Advances in drilling fluids have made geothermal drilling easier and more efficient while increasing geothermal performance on installation. Today, we’d like to highlight CETCO’s research into different grouting techniques and has produced several strong recommendations for the use of Graphite grouting techniques over traditional sand.  Their Graphite, Geothermal Grout, and TC Booster products can exponentially increase thermal conductivity. To explore this topic further, we would like to share a publication in National Driller stating that “a mix of 400 pounds of sand with as little as 24 pounds of graphite will give values that are higher than most portable thermal conductivity equipment can even measure”.  Read the entire article here.
