Fields use FPSOs; Buzios alone reached 1 million barrels of oil equivalent a day operated with six platforms.
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. Distribution partners for Santos Basin are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP65 to IP68 sealing | IP68 design |
| Drop and shock | A stated drop height onto concrete | Specification on request |
| Explosion protection | A separate certificate and marking | In progress; not issued |
| Where it applies | Santos Basin: Gas compression and export, Offloading areas, Platform process modules | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Santos Basin. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

Pre-salt units are far offshore, so crews and equipment move by helicopter and supply vessel.
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.
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, 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.
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.
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Santos Basin. Offshore in the South Atlantic, salt, spray and heat challenge any electronics. IP68 resists water and dust ingress, which helps on open decks. It is not an explosion-protection rating, and it does not replace the Ex marking operators check.
A distributor for Santos Basin would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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.
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.
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are in progress.
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.
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.
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.
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.
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.
