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.

Intrinsically Safe Mobile Phone in Campos Basin
The Campos Basin is an offshore oil province off Rio de Janeiro and Espirito Santo states, covering about 115,000 square kilometres. 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. This page explains what to look for in an intrinsically safe mobile phone for Campos Basin, and where the IS-04Z1 stands against that list today.

More about Campos Basin that matters for portable equipment
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.
Campos Basin: background
Offshore exploration began in 1968 and the first well was drilled in 1971; the Garoupa field was found in 1974 and the first production came from Enchova in 1977 at 124 m of water.
Campos Basin: geography and layout
The Campos Basin covers about 115,000 km2, almost all of it offshore, with only about 500 km2 onshore near Rio de Janeiro, and is one of 12 coastal sedimentary basins in Brazil.
Campos Basin: projects and investment
By 2003 some 41 oil and gas fields had been discovered 50 to 140 km from the coast in water 80 to 2,400 m deep, and the basin was producing about 1.21 million barrels per day.
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 Campos Basin. A mature basin with many older units needs regular maintenance, so inspectors and technicians make frequent rounds. An intrinsically safe handheld lets them record findings and view procedures without leaving the deck. The IS-04Z1 is designed for such rounds, once certification is complete.

Specifying an intrinsically safe 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 intrinsically safe 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 intrinsically safe mobile phone in Campos Basin cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated 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 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.
