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.
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. Distribution partners for Campos Basin are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Campos 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.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Campos Basin: Crude storage and offloading, Gas compression, Platform process modules | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Campos Basin. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The companies on site and the hazardous-area types a handset is likely to meet there.

People and supplies are largely handled through Macae, which has an airport used for offshore flights and the Imbetiba port.
A 65 million barrel discovery was announced by Petrobras near the Barracuda field in February 2010, showing continued exploration activity in this mature basin.
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.
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.
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.
“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.
A distributor for Campos 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.
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.
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.
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.

Macae hosts Petrobras' basin base, an airport with offshore helicopter operations and over 4,000 companies set up in the city. That concentration makes it the usual staging point for spares and servicing. Confirm freight, customs and storage arrangements with your local contractor.
Mostly by helicopter from the Macae area, with some supply by sea. Fields lie 50 to 140 km offshore, so transfers are weather dependent. Confirm helicopter operator rules about batteries and powered devices, and ask whether your equipment must be stowed or certified for the aircraft.
Largely at Macae, which handles people and supplies for the basin and has the Imbetiba port and an airport used for offshore flights. Equipment is commonly checked onshore first. Confirm approvals, documentation and delivery routes with the operator and its contractors.
