Well intervention: workover and pulling
Well intervention is the SME heart of the oilfield: the most fragmented, lowest capital-barrier segment of Vaca Muerta. Every well the RIGI triggers adds to a base of ~4,300 producing wells that demands maintenance throughout its useful life —and behind it comes the refracturing wave of ~2,500 old wells—. You don't enter by competing with the majors in the frac's coiled tubing: you enter from the side, with light pulling/workover (USD 0.9-1.5M per rig) and the ramp of Neuquén local content, which already channels ~46% of the contracted amount to the province's SMEs.
The TAM of the full intervention segment breaks down into three legs with opposite dynamics. The addressable crack is the SME-fragmented block (workover + pulling); the coiled tubing and the primary-frac wireline/snubbing are mostly majors' and equipment-niche territory.
The engine is the RIGI mega-developments; the entry lever, by contrast, is 100% provincial Neuquén (local content + investment regime). Each rule opens in the reforms panel on the home page, with its status and primary source.
enablesLey Bases: the RIGI is bornThe RIGI triggers the mega-developments (YPF LLL, Pluspetrol, Pampa, Tecpetrol): more wells drilled = more stock of producing wells demanding recurring intervention throughout their useful life.see the reform →enablesCompre Neuquino: preference for the local supplierThe institutional ramp of the SME niche: the certified Neuquén supplier enters with a 9%/6% preference margin and the right to match the best outside offer. It already channels ~46% of the contracted amount to Neuquén SMEs.see the reform →enablesInvest in Neuquén: the 'Neuquén RIGI' that starts at USD 500,000Starts at USD 500,000 —the size of a services SME—: Turnover Tax/Stamp exemption + 10-year fiscal stability for the equipment settled in the basin.see the reform →enablesA 20% tax credit: it rewards buying from the Neuquén supplierThe other pincer of local content: the operator that contracts you recovers up to 20% in tax credit if it buys from a Neuquén supplier.

These are the ones moving demand for this niche — each with its investment and status.

split
National fleet >25 pulling + >20 workover + >35 drilling. Sold its San Jorge Gulf business (12 workover + 12 pulling, ~750 workers) to CONCENTRATE on Vaca Muerta; YPF mega-contract.
Largest rig fleet in the country (~155 nationwide). Auctioned ~10 rigs from the San Jorge Gulf in 2025 (ref. capex: pulling ~USD 0.9M, workover >USD 1.5M).
Brought a snubbing unit from the U.S. ~3 years ago for wells with >4,000 m laterals (the longest-lateral wells in the country) and operates the only snubbing unit in the basin. Gap = second snubbing operator.
Long-reach CT (records 7,285-7,436 m with YPF), plug-and-perf wireline. Same firms that dominate fracturing (equipment-niche territory). Tenaris adds 2 CT units; Calfrac entered wireline and refracturing studies.
Clear: 4 → 8 pulling rigs + CRT from Canada. Jet Oil: integrated light flush-by/pulling/workover rig (>45 interventions/month, INTI-validated). ~46% of the amount contracted by the industry in H2-2025 was absorbed by Neuquén SMEs (>800 companies). It is the SME heart of the niche.
Don't compete with the majors in the coiled tubing and wireline of the primary frac (that's where SLB, Halliburton, Tenaris are —equipment-niche territory—). The well's after-market has doors according to your pocket:
Low capital — light SME pulling/workover: with USD 0.9-1.5M you buy a self-transporting rig; demand is recurring and dispersed across ~4,300 producing wells and no player monopolizes it. Model already proven: Clear Petroleum (from 4 to 8 rigs), Jet Oil (INTI-validated), Bentia.
Higher margin — long-reach coiled tubing + fast milling for the drill-out of each new well's 20-28 plugs: real bottleneck (lack of CT in the country for 2,500-3,200 m laterals).
The wave coming — refracturing: ~2,500 horizontal wells from 2015-2019 with obsolete completions; the pumping belongs to the big player, but the wireline/CT/workover around it belongs to this niche.
Almost zero rivalry — 2nd snubbing operator: today AESA (YPF) operates the only unit in the basin; for extra-long lateral wells where CT buckles, snubbing is the only alternative. High capex (~USD 20M ref.) but no competition.
The CT/wireline/snubbing of the primary frac (SLB/Halliburton/Tenaris, AESA in snubbing) is equipment-niche territory, captive. It is not the entry point. estim
Addressable: light SME pulling/workover over ~4,300 producing wells (low barrier, USD 0.9-1.5M/rig, real fragmentation) + long-reach CT for drill-out (bottleneck: lack of CT in the country) + 2nd snubbing operator. estim
An SME with 4-8 certified pulling rigs (Clear/Jet Oil model) or long-reach CT takes a share; ~46% of the amount contracted in H2-2025 already went to Neuquén SMEs. estim

Concentration FRAGMENTED with a long SME tail (the opposite of fracturing, which is a duopoly). Light pulling/workover has a low capital barrier (USD 0.9-1.5M/rig) and demand dispersed across ~4,300 wells: the MOST SME-friendly segment of the oilfield. Sub-segments that ARE concentrated: snubbing (de facto AESA monopoly), long-reach CT and complex wireline (SLB/Halliburton/Tenaris) — those belong to the equipment-niche territory.
The obvious name is not always the client, and intervention procurement is not uniform: YPF self-supplies via its arm AESA, the other operators outsource, and there is a layer of subcontracting from the big fleet players. The different doors of the money flow:
Vista, PAE, Pluspetrol, Pampa, Tecpetrol contract rigs under framework agreements. YPF, by contrast, internalizes the bulk via AESA (semi-captive): for third parties, the direct door is the operators that don't have their own arm.
DLS Archer and San Antonio Internacional win the framework agreement with the operator and subcontract SME rigs/crews — the lowest commercial-risk entry route for a new SME.
Same firms that dominate fracturing (SLB, Halliburton, Tenaris, Calfrac) — equipment-niche territory; the owner usually reserves the purchase of the critical completion service.
Today only AESA (YPF) has a unit. A 2nd operator would need a take-or-pay with an operator other than YPF (PAE, Vista, Pluspetrol) to amortize the capex (~USD 20M ref.).
It's not 'what breaks it': it's the dashboard to enter at the right moment. The data point that signals intervention demand is accelerating:
Workover/pulling is RECURRING opex on the installed base, not a one-time consumption like pipe. Unlike OCTG (which is consumed when drilling and follows the FLOW of the month's new wells), intervention follows the accumulated STOCK: every connected well adds to a base that demands maintenance —pump, rod, tubing changes, sand cleanout— throughout its 20-30 year useful life. A stock growing ~10-15%/year foreshadows a growing, sustained intervention demand, independent of the specific drilling pace. It is a different indicator from the OCTG one precisely because it measures the accumulated asset, not the flow.
Secretariat of Energy — production dataset per well, monthly and by basin (the stock = wells with production > 0 in the month). ↗The monthly count of active workover/pulling rigs is NOT public (it is estimated by ratio over drilling rigs). To anticipate even earlier: the SME fleet expansion (Clear from 4 to 8 rigs) and the % of the contracted amount going to Neuquén SMEs (~46% in H2-2025) signal that demand runs faster than the installed local supply.
The national leaders concentrate their fleet in Vaca Muerta and can saturate the segment. thesis
Workover lives off the producing stock + refracturing; if the focus stays 100% on new wells, the wave of intervening old wells is delayed. thesis
The workover + pulling leg —the SME focus— is built bottom-up from a few variables. The honesty caveat: the daily rig rate is not public in Argentina, so the result is a wide band, not a precision figure. Each variable carries its freshness stamp.
The coiled tubing leg is calculated differently (~500 new wells × USD 120-220k/well of drill-out) and is mostly equipment-niche / majors' territory; it does not enter this SME-focus formula.
The number rests on a few variables. Change one and it recalculates itself; each carries its freshness seal — how often it is worth revisiting. estim
Every figure is checked against its source before we publish it. Here we show what backs it — and where the verified data ends and our estimate begins.
We bound the number to the SME portion that does not overlap with frac equipment: workover and pulling over the base of ~4,300 producing wells, a verified figure. The scale of the local fabric too: 46% of the amount contracted in the second half of 2025 went to Neuquén SMEs. What keeps the number as a wide band rather than an exact figure is the daily rig rate: it is not public in Argentina, so we give a range instead of inventing the data.
