Far from shore
Pre-salt units are far offshore, so crews and equipment move by helicopter and supply vessel.

ATEX and IECEx Mobile Phone Distributor in Santos Basin
The Santos Basin is an offshore province in the South Atlantic, roughly 300 km south-east of Santos, spanning about 352,000 square kilometres and holding major pre-salt fields such as Tupi, Buzios and Mero. Pre-salt reservoirs are ultra-deep carbonates, roughly 5,000 to 7,000 m total depth below a thick salt seal, which drives the high-pressure, high-temperature design of wells and topsides. Distribution partners for Santos Basin are being identified ahead of the Q4 2026 launch of the IS-04Z1.

WhereSantos Basin
Short answer. Santos Basin has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

What Santos Basin means for portable equipment
Gas export
Pre-salt gas reaches the onshore Boaventura plant at Itaborai through the Rota 3 pipeline.
Field notes · Santos Basin
More about Santos Basin that matters for portable equipment
Santos Basin: projects and investment
Giant fields found since 2007 include Tupi (about 8 billion barrels), Jupiter (about 1.6 billion barrels and 17 trillion cubic feet of gas) and Libra, estimated at 8 to 12 billion recoverable barrels.
Santos Basin: geography and layout
Santos, Guaruja and Ilhabela sit in the central onshore part of the basin, and the city of Rio de Janeiro is on the northern coastal edge, so supply bases cluster along that coast.
Santos Basin: industry on the ground
Associated gas in some pre-salt fields contains more than 20 percent CO2, which is separated on the FPSO, compressed and reinjected, so gas compression and high-pressure CO2 handling are routine offshore.
Santos Basin: geography and layout
The basin is known for thick salt layers that deform into structures in the subsurface, and the pre-salt Tupi reservoir sits in microbialite carbonates of the Guaratiba Group beneath that salt.
The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Santos Basin. Santos Basin units, run by Petrobras, Shell, Repsol and Eni, are far offshore, so reviewers want certificate evidence verified before equipment is sent. A dual ATEX and IECEx route is designed to help international FPSO contractors. The IS-04Z1 has no certificate yet.

Questions · Santos Basin
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in Santos Basin today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an ATEX and IECEx mobile phone in Santos Basin cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Which areas at Santos Basin would use it?
Likely candidates are platform process modules, wellhead areas, gas compression and export, offloading areas. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Santos Basin?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Santos Basin.
Who operates in the Santos Basin?
Petrobras is the main operator, often in partnership with other energy companies on licences. Because induction rules and approved-device lists are set per operator and unit, confirm requirements for each asset you will visit.
Does high CO2 content change device requirements?
It is a process condition rather than an Ex rating, but gas detection, procedures and area classification take it into account. Mobile devices still follow the unit's zone rules, so confirm with the operator which markings and approvals the platform accepts.
Do all Santos Basin operators follow the same rules?
Not necessarily. Petrobras, Shell, Repsol and Eni each set their own policies for portable devices and approvals. Ask each operator for its Ex equipment policy and the classification of the specific unit. Confirm with the site operator before ordering.
