Offshore climate
Salt, humidity and heat are normal, so equipment is commonly checked onshore before it goes offshore.

Ex-Proof Mobile Phone in Campos Basin
In 2020 Petrobras sold shallow-water concessions including Enchova, Bicudo, Bonito, Pampo and Badejo to Trident Energy, so the operator mix in older shallow fields has diversified. In December 2025 it had 39 platforms in operation, 18 of them FPSOs, creating Zone 1 areas on process decks and in storage and offloading areas. If you are specifying an Ex-proof mobile phone for Campos Basin, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Local conditions · Campos Basin
Site conditions at Campos Basin: what wears and what limits equipment
Mature basin
The basin produced 828,600 barrels of oil equivalent a day in 2025, well below its 2011 peak, with many older units needing regular maintenance.
Field notes · Campos Basin
More about Campos Basin that matters for portable equipment
Campos Basin: projects and investment
A 65 million barrel discovery was announced by Petrobras near the Barracuda field in February 2010, showing continued exploration activity in this mature basin.
Campos Basin: infrastructure
Production comes from varied reservoir types, including turbidite sandstones, fractured basalts, coquinas and limestones, which leads to a mix of facility designs and well services across the basin.
Campos Basin: rules and approvals
Roncador ranked first among the top fields of the Santos, Campos and Espirito Santo basins in 2010 at 129.7 million barrels of oil equivalent, and the Campos Basin had eight discoveries in 2011.
Campos Basin: who works there
In 2014 about 62.7 percent of Petrobras' Brazilian proved developed reserves were in the Campos Basin, and the company set its basin headquarters in Macae in the 1970s.
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 Campos Basin. The sheet describes Zone 1 areas on process decks and in storage and offloading areas. A label check should confirm Zone 1 suitability, plus gas group and temperature class for the products handled. The IS-04Z1 marking target II 2 G Ex ib IIC T4 is a target only.

Specifying an Ex-proof mobile phone for Campos 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 · Campos Basin
Frequently asked questions
Can we buy an Ex-proof mobile phone in Campos 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 mobile phone in Campos 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 Campos Basin would use it?
Likely candidates are platform process modules, wellhead areas, crude storage and offloading, gas compression. 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.
Do older and newer platforms in the Campos Basin differ for device approval?
Not necessarily, but the operator differs. Some shallow fields passed to Trident Energy in 2020 while Petrobras runs many others, so induction rules and approved-device lists can vary. Confirm with each operator's safety team which markings and approvals they accept.
What hazardous areas appear on Campos Basin production units?
Typically wellheads, separation and gas treatment, compression, crude storage and offloading, and the helideck fuel area. Classification drawings from the unit operator give the exact zones, gas groups and temperature classes, so request them before choosing a handheld device.
Are older platforms a particular concern for device selection?
The basin is mature, and many older units need regular maintenance, so rounds are frequent. That favours a rugged, intrinsically safe handheld, but each platform has its own classification. Ask the operator for it rather than assuming that one marking suits every unit.
