What we have on this project for a supplier
Who decides the purchase, who you invoice and where a new supplier registers.
Which lines each phase buys and when the window opens for each one.
Which they are, why it will need them and who could provide them.
Who they are, what each one does and how to sell to them.
All of this is surveyed and verified against its source. Crossed with what you sell —which of them your products suit, how to reach it and when— it is in your company report. Request the report
We cross what you manufacture or do against the 3 phases of this project and tell you which ones you fit into and when each one buys. Two pages, with the evidence behind them.

The works, milestone by milestone
The Official Gazette publishes Resolución 1771/2026 of the Ministry of Economy, which approves the adhesion to the RIGI as a PEELP (strategic long-term export project) with an adhesion date of Sep 9, 2026. Declared schedule: stage 1 from Nov 1, 2024 to Feb 28, 2027 (USD 1,635 M: central plant, oil pipeline, gas pipeline and 16 wells); stage 2 from Mar 1, 2027 to Jun 30, 2029 (USD 1,268 M: expansion of the plant to 70,000 barrels per day and 91 wells); stage 3 from Jul 1, 2029 to 2054 (USD 3,529 M: the last 273 wells).
The Minister of Economy announces that the Comité Evaluador approved the project's entry into the RIGI for USD 6.4 billion, with 3,100 direct and 4,800 indirect jobs and a planned output of 70,000 barrels a day.
The basin's vice-president reports 30 % works progress, three drilling rigs, twelve wells able to produce, around 400 wells in the full development and a peak of 4,000 people.
The government of Neuquén announces the project's RIGI filing: USD 2.4 billion through 2028, a 90/10 split between Tecpetrol and Gas y Petróleo del Neuquén, around 380 wells, 70,000 barrels a day, a 35,000-barrel module in March 2027 and its doubling towards July 2027.
The block's development drilling campaign begins; in April 2026 three rigs are working in the area.
The Phase 2 environmental impact study is signed, prepared by the consultancy Physis SAS: 85 new pads with an average of four wells each, three separation batteries, the early production facility, 10 disposal wells, the reinjection aqueduct, the gas lift network, the export pipeline to Auca Mahuida, medium-voltage power lines and internal roads.
Work on the central processing facility begins with Techint Ingeniería y Construcción, under an EPC contract on a «Cost + Fixed Fee» basis.
The Environment Secretariat grants the Phase 1 environmental licence through Disposición DI-2024-549-E-NEU-SAMB#MERN: 15 pads, 3 disposal wells, flowlines, production gathering, export pipelines, fuel gas network, water intake and aqueduct, water wells with their distribution system, and power lines.
Decreto 1530/2022 ratifies the block's amended pilot plan, which evacuates initial production through Chevron facilities at El Trapial Este with a pipeline to Battery 6, operated by Tecpetrol along its whole length. The recitals mention the contract with Chevron for treatment of gross production, crude transport and dispatch, water disposal and gas conditioning.
Decreto 1392/2019 grants Gas y Petróleo del Neuquén the unconventional exploitation concession over Los Toldos II Este «for a term of thirty-five (35) years... from 11 May 2019», covering 77.8 km², and approves the joint venture contract with Tecpetrol signed on 5 June 2019.
The same decree sets the pilot plan: one vertical well later horizontalised and completed plus two horizontal wells within no more than two years, for around USD 38,000,000, plus infrastructure and other investment within no more than three years, for around USD 15,000,000. And it sets the payments to the Province: USD 2,825,000 in corporate social responsibility and USD 1,500,000 as a contribution to infrastructure programmes and works, both within ten business days of the decree being published.

The infrastructure that stays standing once the works end, with its size and its source.
Export pipeline from the central facility to Auca Mahuida
Productivemetres of 24-inch line, maximum flow of 330,000 barrels a day
the block and, through the connection with Oldelval at Auca Mahuida, the basin's trunk evacuation system
Verbatim from the technical sheet in the environmental study: API 5L X56 steel, 24 inches nominal and outside diameter, «Length (m) 37,883.91», origin «CPF LT2E», destination «Auca Mahuida – Oldelval – Transport Pipeline», «Maximum flow 330,000 bopd», no internal coating and three-layer external coating, 0.438-inch wall thickness, design and maximum allowable pressure of 97.8 kg/cm², operating pressure of 38 kg/cm², buried. Upstream it carries a custody transfer metering unit with calibration prover, flow computer and automatic sampler.
Central Processing Facility (CPF), with modularised treatment trains
Productivethe block for the 35 years of the concession: it is the plant that separates and treats everything the wells produce
The design capacities are declared by phase in the environmental study: «Phase 1: 2,385 Sm3/d (Hydrocarbon) / 708.8 Sm3/d (Water) / 250.4 MSm3/d (Gas). Phase 2: 4,770 Sm3/d (Hydrocarbon) / 708.8 Sm3/d (Water) / 500.9 MSm3/d (Gas)». The second phase doubles hydrocarbon and gas treatment and leaves water unchanged.
85 drilling pads with their access roads
Productive× 235 metres and 29,240 m² each, 2.48 km² in total, with 506,998.82 m³ of imported aggregate
the block: they are the platforms from which drilling and production run for the whole concession
Each PAD carries an average of four wells and an internal pit of 10 × 40 metres. The declared imported aggregate is 5,964.69 m³ per PAD and 506,998.82 m³ for all 85. thesis It is the best quantified quarry demand in the project.
Three separation batteries
Productivethe block: they gather and separate production from the pads before sending it on to the central plant
The three batteries separate water and hydrocarbons from the PADs' output before sending it on to the central plant. Each carries twelve skid-mounted units —low-pressure separator, compression skid, accumulator tank, booster pump, transfer pump, hydrate- and corrosion-inhibitor injection, high-pressure header metering, instrument air, fuel gas, flare knock-out drum and relief system— plus four 1,500 kW compressors fuelled by the wells' own gas, with room set aside for more machines. Between them the three consume 42,082.80 m³ of imported aggregate, 14,027.60 m³ each. Relief systems are designed to API 520 and 521, and the safety valves are certified to API 526 in pairs: one in service, one on standby.
Reinjection aqueduct and gas lift network
Waterthe block: the aqueduct carries produced water to the ten disposal wells and the gas lift network sustains output from mature wells
The reinjection aqueduct and the gas lift network appear among the Phase 2 facilities, alongside «10 disposal wells». thesis The aqueduct and the disposal wells handle produced water inside the area, without taking it out of the block.
Medium-voltage power lines across the field
Powerthe block: it is what allows production to be electrified rather than run on diesel generation at each location
The medium-voltage lines are within the Phase 2 scope and were already in the Phase 1 scope («power lines» in licence DI-2024-549). On-site generation declared by the operator for the project is 50 MW prob.
- What it already pays in taxes and royalties — We have not broken down this project’s local fiscal contribution: the primary source that sets each item still has to be opened, and an act of the State is not published on press backing.
- Who promised what — We have not surveyed the public promises about this project. A dated, verifiable commitment with its source closes them.
What could stall it
risks and how to track them
- What could stall it — We have not documented this project’s risks. An identifiable vector with its source closes them.
- How to tell whether it is advancing — We have not defined this project’s indicators: what observable fact marks its progress still has to be identified.
How we verified this
the act, the gaps and the sources
The RIGI act, in detail
We have not looked for this project’s RIGI act in the Boletín Oficial.
What we could not confirm
There are 5 in this project. Each says why it could not be confirmed and what it would take to close it.
H-01The project's OPERATIONS headcount, and the 4,800 indirect jobs in the minister's announcement+
The phase ambiguity is resolved: Tecpetrol's own thread of Aug 19 says "more than 3,100 jobs at peak construction", that is, construction, and that figure is already recorded. What no one has published is how many people stay on once the field is producing, which is the number that decides whether a town gains population or just a construction spike. The 4,800 indirect jobs are not broken down by phase in any source either.
H-02What Tecpetrol asks of a new supplier in money and in payment terms+
The suppliers page publishes the procedure and the reference standards, but not the detail of the 83 requirements, nor payment terms, nor minimum working capital, nor whether provincial roots carry weight. Without that, an SME knows where to knock but not whether it can afford to.
H-03The exact date of Disposición DI-2024-549 and its full text+
The Phase 1 environmental licence is known only through the transcription in the Phase 2 study: number, file and scope. The act itself is not published in the open and neither research pass found it.
H-04Who is building Phase 2: the 85 pads, the three batteries and the export pipeline+
The work is measured down to the metre in the environmental study, but the project's only published contractor is the EPC for the central facility. For the rest there is no public award, and the project says it coordinates between 700 and 800 companies without publishing the list.
H-05How much aggregate is needed per year and where it comes from+
The study declares 506,998.82 m³ of imported aggregate for the 85 pads, but does not give the pace or the source quarry. Without that, an aggregate supplier knows the total volume and not whether the logistics work for them.
