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

Intrinsically Safe 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. 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. Distribution partners for Santos Basin are being identified ahead of the Q4 2026 launch of the IS-04Z1.

Santos Basin: industry on the ground
Petrobras reported pre-salt production of 2.45 million barrels of oil equivalent a day in 2025, about 82% of its total output, which shows how much of its production now comes from pre-salt fields.
Santos Basin: geography and layout
The Santos Basin spans about 352,000 km2, mostly offshore, around 300 km southeast of Santos, and borders the coasts of Rio de Janeiro, Sao Paulo, Parana and Santa Catarina states.
Santos Basin: projects and investment
Two new pre-salt platforms started in 2025 in the Santos Basin: the FPSO Almirante Tamandaré at the Búzios field and the FPSO Alexandre de Gusmão at the Mero field.
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.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Santos Basin. Rounds on a large FPSO, such as one of the platforms at Buzios, cover long distances between modules. A handheld that is intrinsically safe lets inspectors work with checklists and photos wherever they are. The IS-04Z1 is designed for this, subject to certification.
The route · distribution
Distributing the IS-04Z1 in Santos Basin
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.

Questions · Santos Basin
Frequently asked questions
Can we buy an intrinsically safe 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 intrinsically safe smartphone in Santos Basin cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
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.
