NexTitan is a downhole drive system that applies weight on bit at the bit and reacts to downhole conditions in real time.
How it worksNo. NexTitan controls weight on bit at the bit. Directional control stays with your existing directional assembly.
NexTitan is rated to 175°C circulating, with reservoir temperatures up to ~300°C using active mud cooling of the electronics.
Yes. The tool responds to the formation at the bit face; it is not tuned to one rock type.
Granite is hard and abrasive, so the rate of penetration drops and PDC cutters wear or fracture quickly. Each worn bit means pulling the whole drill string out of the hole, replacing the bit and running back in, which at depth takes most of a day. Vibration (stick-slip) makes cutter damage worse. NexTitan addresses this by applying weight on bit at the bit and reacting to vibration downhole.
Roughly half. Published estimates for enhanced geothermal systems put drilling and well construction at 40–60% of total project capital cost, and the share rises with depth. That is why drilling speed in the hard-rock section decides whether a deep geothermal project is economic.
Calculate drilling costDeep geothermal drilling means drilling wells into hot rock at depths of roughly 3 to 5 km, where temperatures reach 150–300°C, to produce heat or power. At those depths the well usually passes through crystalline basement such as granite, which is harder and slower to drill than sedimentary rock. Enhanced geothermal systems (EGS) and closed-loop projects both depend on it.
Most standard downhole electronics are rated to around 150–175°C. Deep geothermal targets are often hotter than that, which limits which tools can be run.
