Well cementing and abandonment
Cementing new wells is captive to the large service companies, but regulation opened a market alongside it: plugging and abandoning wells, on a large liability — some 970 unconventional wells with no production and up to 2,000 conventional ones YPF has to plug. That is ~USD 25-75 M a year of abandonment cementing and remediation, at a ticket of USD 30-60k per well estim. ⚠️ And it is not a wave: the work comes in file by file, one area at a time, and the province itself said it would allow up to ten years for the largest block. Whoever sets up a crew joins a calendar that is drawn up every 31 January.

What the market is made of
The niche itself is the part that does NOT overlap with anything: the primary cementing of new wells (the bulk of the activity, ~USD 185 M) is captive to the big OFS and already counted in the equipment niche. Your market is made of two legs, both addressable:
The primary pumping of new wells is captive (big OFS + the operators' internalized arms) and is also already counted in the equipment niche. Non-addressable. estim
Addressable: P&A/plugging-abandonment (stock ~970 unconventional + YPF's conventional plan, driven by the rules rather than by the market) + class G cement/additives as input + cementing QA (cement bond log). estim
Ticket ~USD 30-60k/well x hundreds of P&A wells/yr; a specialized SME or a JV with a mid-sized operator takes a portion. thesis
Who really pays?
The obvious name is not the client. The operator is legally responsible for the abandonment, but the cement is bought by whoever pumps it — not by the operator. Three distinct doors:
The operators, some of them through their internalized services arm. YPF submitted its conventional well abandonment plan to Neuquén.
The large service companies and the operators' internalized service arms — they buy the cement and place it in the well's annulus.
Operators + the Neuquén Environment/Energy Undersecretariat as the one that requires compliance (the demand is born from the rule).

Abandonment is not triggered by an inspection: it is triggered by a concession expiring and by the schedule each operator files in January. These four warn you before any tender does.
The driver is regulatory (Decreto 1631/06); if the province/operators postpone abandonment, the market does not materialize. thesis
The casing + cementing turnkey (see Tenaris above) can occupy the well's surface segment. thesis
The opportunity in depth
The opportunity in depth
Plugging and abandonment, the newest gap: a stock of some 970 unconventional wells with no production, plus the conventional abandonment plan YPF is negotiating with the province. It is triggered by the rules, not by the market. Ticket of USD 30-60k of cementing per well estim. ⚠️ It is not an empty segment: it is a segment the three large service companies do not prioritise, and where there are already registered local providers.
Class G cement and special additives (anti-lost-circulation, lightweight slurries) as an input, to sell to the OFS and the internalized arms. Lost circulation is a real and recurring technical problem in Vaca Muerta.
Quality control / cementing evaluation (cement bond log) to certify aquifer isolation —mandatory and politically sensitive—. Low capital intensity.
Internalization / JV with a mid-sized operator: operating cementing units with far less capital than a frac set.

split
Global cementing leaders (a historic core business); custom solutions for lost circulation (a real technical problem in VM). They integrate cementing into their service.
Internalized services arm of the largest operator with an explicit cementing mandate; since it is the largest operator, it cements much of its own activity.
Entered Argentina 15 years ago THROUGH cementing (later shifted to fracking). Installed capacity and know-how; key client a mid-sized operator.
The services arm (former Weatherford) cements its operator's own activity (internalization model). The global company, with an eroded position after selling part of its Argentine business (2021).

Launches a turnkey of surface casing construction + casing cementing with casing drilling, available 2027. It would enter through the surface segment: a signal of the pipe maker integrating toward the service.
The jobs it createsReal environmental remediation (un-abandoned wells are an environmental liability that isolates aquifers); employment of abandonment crews. It is the environmental/for-the-people leg of the oilfield. thesis
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 High but less extreme than in fracking. The 3 big OFS dominate >65% globally; in VM it fragments through internalization (the operators' services arms cement their own activity), a lower capital barrier than a frac set, and a legacy of specialists (a frac company entered through cementing). No public per-company ranking for VM. And on the local side there are names: the provincial registry of certified suppliers, under 'Drilling and well-specific services', lists a local company that offers integral well abandonment and cementing (registry counted on 14 Sep 2026).
The rule that moves it
The market for abandonment is created by provincial and environmental regulation (the obligation to plug the well and isolate the aquifers).

Where the number comes from
~USD 9-36M/year from the pure calculation, read as ~USD 10-45M (the high end assumes the regulatory pace accelerates) + ~USD 15-30M of remediation = ~USD 25-75M/year, the net niche band
See the calculation, the variables and how it was validated
The net niche is built from a few variables. The big leg —the plugging and abandonment (P&A)— is bottom-up: how many wells are sealed per year × how much the cementing of each abandonment costs. Each variable carries its freshness seal.
The remediation / squeeze leg (~USD 22 M) is not a formula: it is estimated as ~10-15% of the primary and is the fastest-growing segment globally (Mordor, remedial CAGR ~6.5%).
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
We narrow the figure to the part that does not overlap with well equipment — primary cementing is already counted there: only plugging, abandonment and remediation. The driver is regulatory and has been read in its primary source: Neuquén's Decreto 1631/06, opened page by page, requires a minimum of two cement plugs per well, an abandonment plan with a schedule due every 31 January, deadlines of 3 and 6 months to plug depending on where the well sits, and a licence to carry it out. Since 2006 there have been 654 definitive abandonments. ⚠️ That 654 compares against some 19,000 wells drilled, not wells pending abandonment: many are still producing. The exact stock of wells still to be plugged can be counted — the Energy Secretariat's monthly file carries the status of every well by province — but what holds this figure up is an estimate of pace, not that count. And the price per well is not public in the basin, so the size is an estimate, not a closed figure.
Coverage: the public registry of Certified Neuquén Suppliers under Ley 3338, counted in full: 1,029 companies, of which 36 in the «Drilling and well-specific services» category, where companies already offering full well abandonment and cementing appear · Sep 14, 2026 · not reviewed: the Provincial Register of Well Abandonment Operators, which is the exact universe, does not publish its list of names —the rule orders a book to be kept and a certificate to be issued to each company—, so how many are licensed cannot be counted from outside
