NexTitan Field Validation Results May 2026: Dual-Unit System Drills Hard Rock
Moving from single-unit validation to a system that drills continuously.
Field Test Phase 1 in February 2026 proved that NexTitan could grip hard rock, generate controlled axial thrust, and operate autonomously in a live wellbore. That was a necessary first step. The next question was harder: could two NexTitan Downhole Drive Units operate in coordination within a single bottomhole assembly, cycling through drive and reset sequences in a synchronized handover pattern that keeps force on the bit without interruption?
Continuous thrust is the critical requirement for autodriller integration and sustained rate of penetration in hard rock. A single DDU drives and resets in sequence, producing an intermittent force profile at the bit. Two units in coordinated handover eliminate that gap, delivering the stable, uninterrupted force that demanding drilling environments require.
The test environment was unchanged by design. The same well at NORCE Ullrigg in Stavanger, Norway: 8.5" nominal diameter, drilled through hard Phyllite at 22,000 psi UCS.
Two NexTitan Downhole Drive Units deployed in Norway. One synchronized system. Real rock.
NexTitan is GA Drilling's modular downhole drive system. It applies weight directly at the bit and controls thrust autonomously based on real-time downhole conditions, eliminating the lag of surface-based decisionmaking.
Field Test Phase 2, conducted in April 2026, deployed NexTitan in Norway in a dual-unit configuration within a live hard rock wellbore. The units were designed to operate in a coordinated handover sequence: as one unit resets, the other drives and thrusts, maintaining continuous force on the bit throughout the drilling cycle.
The test also introduced a new capability: a downhole turbine generator, developed in Q1 2026, ran as an alternative power source to lithium batteries during the second week of operations. Turbine power eliminates battery life constraints — a prerequisite for the extended operational durations that commercial deployment demands.
Dual-unit drilling confirmed. Turbine milestone achieved.
Two NexTitan drive units operated as an integrated system in a live hard rock wellbore. Downhole data confirmed multiple successful handover events per run, with both units cycling in coordination and continuous force delivered to the bit. The result: 66 ft (~20 m) of hard Phyllite drilled with NexTitan in the bottomhole assembly across 7.5 hours of combined drilling and circulation operations.
Force control precision reached ±500 lbf — the best result to date — demonstrating the closed-loop accuracy required for safe, reliable drilling modes.
A downhole turbine generator prototype completed successful operation at depth, confirming the ability to generate electrical power from drilling fluid flow and supply a representative NexTitan operating load. Battery-independent power is now a demonstrated capability, not a future consideration.
The next field test phase shifts the objective from integration validation to measurable performance improvement: demonstrating NexTitan's value proposition through increased effective weight on bit, improved rate of penetration, and active mitigation of drilling dysfunction in hard rock.
