54 rigs drilling, fifteen frac spreads, and no official registry

This is the register of Argentina's active oil and gas equipment fleet: drilling, fracturing, workover and pulling, with a technical file for every unit that has one published. The totals come from the private monthly surveys the industry treats as reference, because the State publishes none. As of July 2026: 54 drilling rigs, fifteen frac spreads, 47 workover units and 72 pulling units. Where two sources publish different figures, the row carries the range and both sources.

The fleet

Four totals, each with its date and its owner

Each segment total is anchored to a single survey, TecnoPatagonia's for equipment and Fucello's for frac stages, and carries the date of the data. The monthly surveys run two weeks behind: the current one is July 2026, and August's was not out when this edition closed. Between workover, pulling and spreads, the service fleet reached 171 units, just under June's peak.

Current totals by segment. Each total is anchored to a single survey; the date is the date of the data, not of this registry.

Fracturing

Five companies split the stages, and the spreads have no names

Halliburton, SLB, Tenaris, Calfrac and SPI pump every frac stage in the country. In July 2026, over 2,010 stages: Halliburton 55%, SLB 26%, SPI 10%, Tenaris 8% and Calfrac 1%, a split that YPF's exclusive contract with Halliburton rewrote during the year.

A rig is called DLS-177 or SAI-652 in the trade press; a frac spread is "Tenaris's third spread". There is no public naming convention for spreads, so the files below carry names coined by this register, and that asymmetry is itself a data point. The other gap is the engine: the only make ever published for an Argentine spread belongs to Tenaris's second one, Caterpillar 3516C engines with CAT transmissions and SPM pumps built by QM Equipment in Mar del Plata.

The move away from diesel is well documented. Five of the fifteen spreads were dual fuel as of February 2026: three of Halliburton's, one of Calfrac's and one of Tenaris's. In August, Tenaris started up the country's first Dynamic Gas Blending Tier IV spread, which displaces over 80% of diesel with field gas. From October, the four electric Zeus spreads of the YPF–Halliburton contract arrive, each with 20 to 30 MW of on-site gas-fired generation.

July's snapshot shows the other side of the record: of the fifteen active spreads, eight worked, five did not pump a single stage, and about 30% of the country's pumping capacity sat idle.

A range in the units column is genuine disagreement between sources, not imprecision: both ends are cited in the row.

Drilling

Rigs do have names, and even their owners dispute the counts

July's 54 active rigs are the highest on record: 41 in the Neuquén basin shale and 13 conventional. Nabors, Helmerich & Payne and DLS Archer concentrate Vaca Muerta's drilling; PAE drills with its own rigs, and a second tier of contractors keeps the conventional basins running in the Golfo San Jorge, Cuyo and Austral.

The range rule works harder here than anywhere else. TecnoPatagonia counted 15 Nabors rigs and 12 for H&P in July; the companies themselves declared 13 and 9 on their earnings calls in late July and early August. Both versions stay in the row, with their sources, because they measure different things: rigs in the country, rigs earning, rigs drilling.

Fleet renewal is under contract. YPF's deal with DLS Archer commits about USD 600 M and seven rigs with managed pressure drilling by 2027, two of them electric APEX 1500s leased from Patterson-UTI; H&P is shipping three FlexRigs from the US on its way to 15 rigs by mid-2027; and the PACE-F24 that Nabors runs for Vista is the country's first grid-connected rig, on renewable supply contracted from Genneia.

The conventional side moved in 2026 too: CGC commissioned its first company-owned rig in Santa Cruz, PECOM drilled Cañadón Perdido again after 30 years with Venver's VV51, Crown Point is waiting on a rig supplied by San Antonio, and Mendoza runs Aconcagua's A-302 plus a Suren rig.

A range in the units column is genuine disagreement between sources, not imprecision: both ends are cited in the row.

Well intervention

The largest fleet is the least documented

July's 47 workover and 72 pulling units together outnumber rigs and spreads combined, and no public source breaks those totals down by company. Workover is also running 17% below a year ago, waiting on the well-abandonment campaigns in the mature conventional blocks.

What is known by name comes from the Golfo San Jorge regional press, which counts units as they start up or shut down: PAE with 7 workover and 17 pulling units at Cerro Dragón, PECOM with the two ex-AESA units at El Trébol, San Antonio and Crown Point returning to Santa Cruz, Velitec in Tierra del Fuego. The table covers 13 of the 47 workover units and 18 of the 72 pulling units; the rest operate with no public attribution.

A range in the units column is genuine disagreement between sources, not imprecision: both ends are cited in the row.

Reconciliation

What the State does publish: horsepower per well, with no owner

The Energy Secretariat's open-data catalog held 178 datasets on September 1, 2026, and none registers equipment: searches for equipo, rig, workover, pulling and torre return zero. The closest thing to a registry is one field in the Adjunto IV fracturing filings: the frac horsepower declared on each well.

That field has two defects that rule it out as a census. The reporting company is the well's operator, not the spread's owner, so the official data cannot attribute a spread to Halliburton or Calfrac. And each operator reports by its own convention: YPF, Total and Chevron write the spread's rounded nameplate horsepower, Vista writes the horsepower actually deployed well by well, and Shell writes 2,000 HP, a value that is not plausible and that the table flags.

Derived from the official Adjunto IV filings: the frac horsepower each operator reports on its wells. The flagged operator is excluded from every aggregate.

The table is regenerated from the official CSV with tools/equipos-adjiv.mjs; the window and the full caveat live in the data file.

The only audited per-country horsepower figure is not official: Calfrac publishes it in its Annual Information Form, 168,000 active HHP in Argentina as of December 31, 2025, with nothing idle. No other fracturing company breaks out its Argentine fleet in its filings.

Limits

What this register cannot say

Terms

Four distinctions the sources tend to blur

Frac spread, set or fleet

The complete assembly that pumps a frac: pumps, blender, chemical unit, manifold and control cabin. Its size is measured in HHP, the pumps' aggregate hydraulic horsepower. Spreads have no public identifiers, which is why this register names them by owner and order of arrival.

Dual fuel, DGB and e-frac

Three distinct steps the press sometimes merges. Dual fuel: a diesel engine accepts a share of gas. DGB, Dynamic Gas Blending: Caterpillar's variant that adjusts the blend in real time and displaces over 80% of the diesel. E-frac: electric pumps with no diesel engine, fed by on-site generation or the grid.

Walking rig

A rig that moves between wells on the same pad without being torn down, lifting and sliding itself. On multi-well shale pads it cuts a move that takes days on a conventional rig.

Workover and pulling

The two well-intervention fleets. Pulling handles light, recurring maintenance, mostly on conventional rod-pumped wells; workover handles the heavy repairs. Sources sometimes publish a single number for both; this register separates them where it can.

Sources

Who counts each thing, and how it gets corrected

Segment totals come from the monthly surveys by TecnoPatagonia and Luciano Fucello (NCS Multistage, fracstages.com), which the trade press reproduces; company counts come from that press, Shale24, Mase, Data Energía, Río Negro Energía and the Golfo San Jorge dailies, plus the companies' own earnings calls and releases. Technical files cite a source per specification, because they are assembled from scattered announcements nobody publishes twice. Some cited outlets block automated access and may require opening the link in a browser.

The full dataset is at equipos-parque.json, under a CC BY 4.0 license, with its schema. The register's own derivations carry the est_ prefix; the absence of an official registry is documented, with its consultation date, in the oficial object of the same file.

Corrections are applied to the row and logged in the correcciones array, with the date, what changed and who flagged it.
