Ex-Proof Smartphone 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. Its FPSOs create Zone 1 areas on process decks and in storage and offloading areas. An Ex-proof smartphone distributor in Santos Basin would carry the IS-04Z1 to these buyers once certification completes.

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.

Conditions in Santos Basin that affect handheld equipment
Far from shore
Pre-salt units are far offshore, so crews and equipment move by helicopter and supply vessel.

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: infrastructure
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.
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.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Santos Basin. The sheet notes Zone 1 areas on process decks and in storage and offloading areas. Gas export from the pre-salt adds gas compression to the mix. A label check compares zone, gas group and temperature class with each unit's classification. The IS-04Z1 target marking II 2 G Ex ib IIC T4 is not yet certified.

Questions · Santos Basin
Frequently asked questions
Can we buy an Ex-proof smartphone in Santos Basin today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an Ex-proof smartphone 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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
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.
