Pipeline integrity and inspection
The regulation in force since May 2026 requires every oil pipeline to be inspected internally within five years of entering service, and repeated every five; Neuquén, on top of that, requires an integrity plan to be filed every year —March for gas pipelines, October for liquids— covering everything from the well to dispatch. That turns every new kilometre of Vaca Muerta into an obligation with a date, and that is the market: the recurring one, not the construction one. The wall is a foreign leader on internal inspection, and you do not compete with it using your own tool. The gap is alongside —construction testing, tank integrity, and the management that coordinates the leader rather than competing with it— and what defends it is not capital: radiographing a weld requires a permit from the Autoridad Regulatoria Nuclear, and there are 414 licensed operators in the whole country.

Who really pays?
The obvious name is not the client. Integrity is paid for by different owners depending on the layer: construction testing is subcontracted by the contractor laying the pipe; internal inspection and tanks are paid for by the asset's operator, directly. Three doors, three clients:
It is subcontracted by the contractor laying the pipe. On VMOS that was two large pipeline contractors, and that lay finished in August 2026; the live project is the Gasoducto San Matías. The precedent is a testing contractor that did the testing on the Gasoducto Néstor Kirchner: 45,378 joints verified.
The carriers and the pipeline operator contract the internal inspection provider directly — the leader has a ten-year contract with one of them, covering more than 5,000 km.
The producer or operator contracts the API 653 certified inspector —or has one on its own payroll, which the regulation allows— and files the sworn statement Resolución 277/2025 requires. Fiscal metering is bought per point where the product changes hands.

see the project →When the window opens
Here it is not a construction job that is watched: it is the calendar, because that is when the purchase is decided. In Neuquén every operator files its integrity plan in March if the pipeline is gas and in October if it is liquids, and the national liquids regulation adds its own annual filing before 31 March. The three dates are in the rules; that it is there that what gets inspected the following year is decided —and that the supplier therefore has to be inside before that— is our own reading. The laying works are no longer the window: the VMOS oil pipeline finished welding in August 2026 and what is left under construction is the San Matías gas pipeline, 472 km until its start-up scheduled for 2028. What only now opens is the clock of the new rule: every pipeline must be inspected internally within five years of entering service and repeat it every five. ⚠️ That deadline can be extended if the operator justifies it by the section's history, so it is enforceable but not rigid. And the four indicators below give warning before the market does.
The construction testing block is transitory and the big pipeline lay finished in August 2026: anyone sizing the business on construction rather than on the recurring part ends up over-equipped. estim
If the internal inspection leader moves down into construction testing and integrity management, it shrinks the spread-out gap. thesis
If the register of operators licensed by the Autoridad Regulatoria Nuclear grows —414 across the country as of 14-Sep-2026— or if construction standardises on automated ultrasound, which needs no such permit, the advantage of having started training people early dilutes. thesis
The opportunity in depth
The opportunity in depth
Local construction testing capacity. What is left to weld is the Gasoducto San Matías, 472 km through 2028, at ~96 joints per kilometre. The slot is as subcontractor to the contractor laying the pipe. Personnel plus mobile or rented equipment.
Tank integrity (API 653). Resolución 277/2025 changed who signs: instead of an auditing firm on a register, a certified inspector now signs a sworn statement, and that inspector may be contracted or be the operator's own staff. It lowered the entry door, but it also shrank the universe: only vertical tanks of 50 cubic metres or more remain covered. The business is the inspector who signs, not the audit that came before.
Integrity management as a service over the network coming into operation: the party that coordinates the foreign leader's internal inspection, the field testing, the tanks and the reporting under an annual contract. It coordinates the leader inside an annual contract.
Metering at the points where the product changes hands, as engineering and metrology: every new point requires auditable measurement. The barrier is technical know-how.

Clear leader in the inspection that runs inside the pipe. Around 30 years in the country, with growing focus on Vaca Muerta. More than 5,000 km inspected at one carrier, under a ten-year contract. It is the wall: you do not compete with your own tool, you coordinate it.
The leader's global competitors in high-resolution internal inspection; their Argentine presence is smaller.
Global certifiers: testing, integrity certification, weld auditing and tank inspection. Strong on large projects; less so on the field testing crew.
Did the radiographic testing of the welds on the Gasoducto Néstor Kirchner: 45,378 joints verified, with operators certified by INTI. Proven capacity at scale.

Argentine testing and integrity firms, and tank inspection under API 653. A spread-out segment where the limit is personnel licensing, not technology.
The jobs it createsIt trains certified inspectors (a well-paid, exportable technical trade) and professionalizes pipeline safety (fewer leaks/environmental incidents). thesis
Internal inspection is closed off by a foreign leader with around 70% —proprietary technology and track record, more than 5,000 km at one carrier—; you do not compete with your own tool. Not addressable. estim
Addressable: construction testing for what is still being welded, tank integrity under API 653, the integrity management that coordinates the foreign leader's internal inspection, and fiscal metering. estim
The recurring part —internal inspection and tanks— is ~USD 50-100 M/yr and does not switch off; construction testing falls to ~5-17 M because the big pipeline lay is finished. A licensed SME takes a slice. estim
Why we do not put a number on it Putting a figure on it takes two prices and neither is published in Argentina: what is charged to test one weld, and what an internal inspection run costs per kilometre. The market figure this page publishes multiplies an international tariff by a service multiplier with no source, so trimming a percentage off it would produce a third unsupported number. The physical side is measured —kilometres, welds per kilometre and the frequency the regulation requires—; the price side is not.
calculate it
The number comes from multiplying the year’s activity by the unit price, and it is cross-checked against independent methods that give the same result.
The full calculation, step by step
Concentration Split in two. High in internal inspection (the foreign leader ~70%, then two global competitors; closed off by proprietary technology and track record). Spread out in field testing, tanks and regulatory compliance: 63 licensed companies across the country, between global certifiers and technical SMEs. What limits that segment is personnel licensing, not technology.
The rule that moves it
Construction is triggered by the RIGI; the recurring demand is held up by two regulations with a written deadline: the Reglamento de Transporte de Hidrocarburos Líquidos (Resolución 119/2026 of the Secretaría de Energía), which requires every pipeline to be inspected internally within five years of entering service and repeated every five, and ENARGAS's NAG-100, which sets the equivalent for transmission gas pipelines.

~USD 5-17 M/yr (construction testing, conservative multiplier)
See the calculation, the variables and how it was validated
The engine of now —testing on the construction that is left— is calculated from a few variables, two of them anchored in a primary source (kilometres and welds per kilometre). The recurring part is not a formula: it goes in the footnote.
The recurring part —internal inspection, tanks under API 653, metering at the points where the product changes hands, and integrity management, ~USD 50-100 M/yr— is not a formula: they are long contracts that grow with the kilometres entering service, with the universe of tanks covered by Resolución 277/2025 and with the metering points. Their tariffs come from the same international reference.
The number rests on a few variables. The formula shows how it moves when each one changes; and each variable carries its freshness seal — how often it is worth revisiting. estim
There is a widely repeated idea the regulations do not support: that in construction every joint is tested at 100 %. The two governing ones were opened and they do not say that: the liquid hydrocarbons transport regulation requires testing at least 10% of each welder's welds per day, and ENARGAS's NAG-100 asks for 10% in location class 1 and 15% in class 2; 100% appears only at river and road crossings, tunnels, populated areas and tie-ins.⚠️ That does not knock the figure down, it corrects why it is what it is. The two projects we could measure tested well above the legal floor: the Gasoducto Néstor Kirchner verified 45,378 of some 55,000 welds verif —82%, not 100%— and VMOS tested every joint by ultrasound because the builder decided to, not because the regulation required it. That is why the calculation now carries coverage as a visible variable and uses ~90%.What does bring the construction block down is the date: welding on VMOS finished on 19 August 2026, so the pace goes from ~550 km/yr to ~250. And the soft part stays declared: there is no published Argentine tariff either per weld tested or per kilometre of internal inspection, so that part is an estimate.
