The article is quite skeptical of Quaise: "While it is exciting to see the interest in geothermal, much of the effort leaves me skeptical. Quaise is staffed heavily by former Schlumberger employees. Schlumberger is known for being too expensive and impractical in many of its business units for shale. It is on-brand that they are building a laser-like drilling technology! Quaise deserves credit for correctly identifying the challenges in geothermal economics and pursuing a path with a greater than zero chance of success. But many of their assumptions are off base. The large, bureaucratic companies you work with at Schlumberger often do things like limit trip speed to 500'/hr. One time tripping fast caused a blowout by swabbing the hole, so no rig contracted by the company can trip fast even if the blowout risk is low. Smaller companies are ripping out of the hole at 4000'/hr. Tripping in granite is like tripping in a cased hole. Most companies will push the speed to the physical limits of the crew and rig. And even at 50,000' depths, on-bottom drilling will dominate total time (assuming a high-temperature motor is available). Both PDC bits and motors suffer from the vibration drilling in hard rock causes. There is a decent chance that PDC and elastomer-free motor assemblies will see longer runs at deep depths because the rock is more ductile." I have no background in energy at all, so I'm not qualified to comment on this at all. Just leaving it here as a counterpoint to the original article.
