NexTitan

NexTitan is an autonomous downhole drive unit that applies and controls force directly at the bit. Think of it as taking 90% of the top drive functionality to the bottom of the well. Instead of transferring weight through kilometers of drill string, the tool generates controlled thrust right where the rock is. In simple terms, NexTitan brings downhole drilling automation directly to the BHA. It is built for drilling oil & gas and geothermal wells, where conventional weight transfer struggles most.

The tool grips against the wellbore just above the drilling assembly and an electrohydraulic actuator applies controlled axial thrust to the bit. A closed-loop control system running at 100 Hz holds that force steady as the formation changes, which delivers stick-slip mitigation at the source instead of damping it downstream. The tool is powered hydraulically by the drilling fluid itself, diverting a small share of flow through its valve system.

Every commercially deployed downhole tool today is passive or reactive: it absorbs vibration, damps stick-slip after it starts, or delivers thrust without control. Surface automation platforms are active but sit at the rig floor, kilometers from the problem which delays their reaction time. NexTitan is the only tool that actively applies and controls force at the bit, downhole, in a closed loop.

NexTitan is designed with three independent failsafe mechanisms. If it loses function, mechanical retraction elements collapse it to a neutral position. In essence, it behaves like an expensive stabilizer. The tool trips out with the string like any other BHA component.

The gripping elements are pistons and their geometry is designed to prevent debris from accumulating behind them. In hard rock testing at NORCE Ullrigg, the tool operated in open hole with simultaneous string rotation and moved along both cased and open hole sections with no gripper-induced sticking. If anything does go wrong, the failsafe design returns the tool to neutral.

The driller keeps full control, the same way a self-driving car still has a wheel and brakes. NexTitan manages force delivery downhole and responds to dysfunction faster than any surface correction could, while the driller keeps doing what they would always do. It assists expertise instead of replacing it.

Yes. NexTitan sits in the bottom hole assembly (BHA) and applies force axially to whatever is below it, so standard polycrystalline diamond compact (PDC) bits work without modification. Measuring while drilling (MWD) and logging while drilling (LWD) tools run above or below it without signal interference, and for directional sections it pairs with a mud motor or rotary steerable system (RSS). The motor or RSS handles trajectory while NexTitan manages force delivery. Connections are standard API.

At NORCE Ullrigg in Stavanger, NexTitan delivered up to 32,000 lbf of open-hole thrust in hard rock, with simultaneous string rotation and no sticking. Earlier multi-unit field testing demonstrated 7.5 hours of continuous drilling. The current test program focuses on continuous drilling length and operating endurance in vertical wells, ahead of the first commercial pilots.

With NexTitan, operators can expect a higher rate of penetration (ROP), longer laterals, longer bit and BHA runs, and fewer trips. That adds up to cost per foot savings, fewer rig days, and less non-productive time (NPT).Operators can also expect less repair maintenance and less risk. The precise multipliers are exactly what the upcoming field test and pilot program is designed to quantify. We'll share results as they come in.

NexTitan is built for oil & gas and geothermal wells where drilling dominates the cost line. It’s ideal for deep, hot hard rock, and long laterals where slow penetration, tool damage, and trips add up. It is not the right tool for very shallow wells or very short runs, where it would add complexity without payback.

The tool is rated to 175°C circulating temperature at the bit. That covers most current geothermal targets, because circulating temperature during drilling runs well below the static reservoir temperature. Pre-job data from active geothermal projects shows circulating temperatures of 100 to 163°C in reservoirs that are far hotter at rest. For hotter wells, active mud cooling extends the reach further, and higher temperature ratings are on the development roadmap.

NexTitan is available for pre-order and is being deployed with partners through structured drilling programs.
