A drilling rig is a small city assembled around a hole. It has cranes, pumps, motors, brakes, pipe racks, pressure-control equipment, miles of cable, screens full of live measurements and crews working around machinery that punishes improvisation. When any critical piece stops, the cost is counted by the minute. NOV has spent generations learning how nearly all of those pieces fit together.
The Houston company - formerly National Oilwell Varco - is often filed under “oilfield equipment.” Accurate, but inadequate. NOV designs and builds capital equipment, sells drill bits and pipe, rents tools, coats and inspects tubulars, repairs rigs, trains crews, streams sensor data and writes automation software. Its products can sit on the drill floor, several miles underground, on the seabed or in an engineer’s browser.
This is not a sleek consumer platform. It is an industrial network assembled through more than 160 years of engineering history, scores of specialist brands and a practical understanding of what failure costs. The company’s real product is uptime.
A hardware company with a memory
NOV traces its lineage to Oilwell Supply, founded in 1862. Another branch began with the company that evolved into Varco in 1908. National Supply and USS Oilwell combined in 1987; National Oilwell and Varco merged in 2005. The result is less a tidy family tree than a box of industrial connectors: Grant Prideco drill pipe, ReedHycalog bits, Tuboscope coatings and inspection, GustoMSC offshore designs, IntelliServ data-carrying pipe and dozens of other technical lines.
That sprawl is the point. An oil company may own the reservoir, and a drilling contractor may operate the rig, but NOV can supply the top drive that turns the pipe, the iron roughneck that makes connections, the blowout preventer that controls pressure, the sensors that watch the process and the spare parts that arrive when wear wins. In downhole tools alone, its offerings range from motors and power sections to agitators and reamers.
NOV reorganized its reporting into two broad segments. Energy Equipment designs, manufactures and supports larger drilling, completion and production systems. Energy Products and Services supplies the technologies consumed, rented or repeatedly used while drilling and producing. One builds the installed base. The other meets it in the field.

The flywheel under the floor
The business logic is easier to see on a rig than in a spreadsheet. First comes an engineered system - capital intensive, safety critical and built for years of work. Every working hour creates wear, inspection requirements and operational data. That generates demand for consumables, spare parts, repair, recertification, training and condition-based maintenance. An upgrade can then make the original asset safer or more productive without requiring the customer to replace it.

In the fourth quarter of 2025, NOV described its mix as roughly 33 percent capital equipment, 49 percent services and rentals, and 18 percent product sales. The labels move with project cycles, but the structure matters: NOV can earn from a newbuild, then from keeping it alive. It reported $8.74 billion in full-year revenue, $1.25 billion in operating cash flow and $876 million in free cash flow for 2025.
A rig becomes a software surface
The most consequential change is that NOV increasingly connects its machines. NOVOS, its reflexive drilling system, automates repetitive activities and lets drillers concentrate on process consistency and exceptions. The Max platform handles industrial data at the edge and in the cloud. Remote monitoring allows an expert to see rig information without standing at the wellsite. This is software with mud on its boots: useful because the company understands the equipment producing the data.
Downhole Broadband Solutions makes the idea literal. Wired drill pipe carries high-speed information along the drill string, replacing delayed glimpses with a live view of conditions underground. In 2026, NOV reported transmitting high-resolution 4D caliper imagery from a third-party tool in real time. It also introduced a wired circulating sub that operators can activate instantly and control independently inside the string.
The competitive claim is not that NOV has discovered data. SLB, Halliburton, Baker Hughes, Nabors and a busy field of specialists all invest in automation and digital workflows. NOV’s difference is the route into the customer: a broad physical installed base, original-equipment knowledge and control over many of the machines being connected. Its 2026 work with Abu Dhabi’s AIQ pairs that industrial foundation with AI-driven drilling optimization through live pilots.
Problem: downtime
Parts, regional repair centers, 24/7 support, monitoring and condition-based maintenance keep expensive assets available.
Problem: blind spots
Sensors, wired pipe, edge computing and shared screens move information between the wellbore, rig and office.
Customers buy fewer surprises
NOV sells to international and national oil companies, independent producers, drilling contractors, well-service firms, offshore vessel owners, engineering contractors and industrial operators. They are not buying identical outcomes. A contractor wants faster, repeatable well construction and equipment it can keep working. An operator wants a safer well, better data and lower cost per foot. A vessel owner wants a crane or cable-lay system supported over its operating life.
What unifies them is the price of a surprise. Pressure behaves badly. Corrosion hides. Pipe connections fatigue. Downhole tools are deployed where a technician cannot casually reach them. NOV’s portfolio is built around controlling those risks - automation to keep people away from the drill floor’s “red zone,” coatings to extend tubular life, pressure-control systems to contain wells and analytics to intervene before an asset fails.
The scale can be almost comic. In 2025, an operator used an NOV motor and ERT power section to drill a 5.7-mile section in a single-bit run, which the company reported as a U.S. land record. A small improvement to a tool at that distance can remove days of work and several opportunities for trouble.
Beyond the barrel, selectively
Oil and gas remains NOV’s center of gravity. Its expansion into other markets is credible where the engineering rhymes. Offshore wind needs heavy-lift cranes, jack-up vessel designs and cable-lay systems. Carbon-capture projects need dehydration, separation, pipe and connectors. Geothermal wells need bits and drilling expertise. Industrial plants need corrosion-resistant tanks, grating and composite pipe.
In May 2026, NOV and TerraFlow Energy said they would evaluate fiberglass solutions for long-duration storage aimed at the rising power appetite of AI-scale data centers. It is an instructive move: NOV is not pretending to be a data-center developer. It is offering materials, manufacturing and field execution where long asset life and corrosion resistance matter.
The Petrobras relationship shows the same method in a harsher setting. NOV’s subsea unit is co-developing flexible pipes with stainless-steel armoring designed to resist CO2-related stress corrosion cracking in deep water. Petrobras shares development risk through a pre-commercial agreement. Later in 2025 it named NOV its best flexible-pipe supplier for the third year running. Partnership here means putting metallurgy on trial under the customer’s actual problem.
NOV’s moat is not one immaculate invention. It is the accumulated knowledge of thousands of machines that cannot afford to stop.
Where NOV fits
In the energy-services market, NOV occupies the machinery room. It is more equipment-centric than the largest integrated oilfield service companies, yet broader than a specialist manufacturer. The portfolio covers a striking amount of the well lifecycle, and that breadth lets separate business units combine systems around a customer’s job.
Breadth also has a cost. Oilfield spending is cyclical; customers delay capital projects when commodity prices weaken. A portfolio assembled over decades can be difficult to simplify. Digital products must work with customers’ existing tools, not merely NOV’s own. And the energy transition creates adjacent opportunities without canceling the economic and environmental scrutiny attached to the core oil-and-gas business.
The company’s culture mirrors its portfolio. NOV describes a decentralized organization with accountable specialist units and room for employees to move across functions - a “choose your own adventure” career, as one employee put it on the company podcast. The useful tension is between local expertise and shared platforms. A drill-bit engineer and a cloud architect do not do the same work, but the modern NOV product increasingly needs both.
That is the clearest way to understand NOV now. It still makes giant machines. It also makes the connective tissue around them: the replacement part, the service call, the clean data point, the remote screen and the next upgrade. In a business built around enormous assets in inconvenient places, connection is not a metaphor. It is how the machinery keeps moving.
