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

Explosion-Proof Mobile Phone 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. 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. This page explains what to look for in an explosion proof mobile phone for Santos Basin, and where the IS-04Z1 stands against that list today.

WhereSantos Basin
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Santos Basin: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

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.
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.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Santos Basin. On Santos Basin FPSOs, explosion-proof refers to platform process modules, wellhead areas, gas compression and export, and offloading areas. Fixed gear may be flameproof Ex d, while a handheld depends on intrinsic safety, which is how the IS-04Z1 is designed. Certification is pending.

Specifying an explosion proof mobile phone for Santos Basin
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Santos Basin
Frequently asked questions
Can we buy an explosion proof 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 explosion proof mobile phone 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still 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.
Is intrinsically safe the same as explosion proof?
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
What hazardous zones appear on pre-salt FPSOs?
Typically the turret and riser area, process and gas treatment decks, compression and CO2 handling areas, crude storage and offloading, and helideck fuel. Zones, gas groups and temperature classes are on the unit's classification drawings, so request them before choosing handheld devices.
How far offshore are the Santos Basin fields?
The basin lies roughly 300 km southeast of Santos and the best-known discoveries are far offshore in deep water, so crew changes are mainly by helicopter and supply is by vessel. Confirm carry-on rules for powered devices with the operator.
How do spares reach a pre-salt platform?
Pre-salt units are far offshore, so crews and equipment move by helicopter and supply vessel. Spares need planning in advance. Confirm approvals, documentation and delivery routes with the operator and its contractors before relying on offshore replacement.
