Anyone looking for an explosion proof mobile phone for Chevron in the United States is really looking at three different jobs: Permian wellpads in the Delaware and Midland basins, the Pascagoula refinery on the Mississippi Gulf Coast, and the Anchor deepwater host in the Gulf of Mexico. This page is for the HSE, instrumentation and IT people who decide what may be carried into those classified areas. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · certification programme in progress
Chevron describes its Permian position as about 1.78 million net acres across the Delaware and Midland basins of west Texas and southeast New Mexico, developed as multi-well pads where several formations are drilled from one surface location. Its US onshore business is run by the Mid-Continent business unit, headquartered in Houston with large offices at Midland and Carlsbad. On the coast, the Pascagoula refinery in Jackson County, Mississippi, processes roughly 350,000 barrels of crude a day, and a premium base oil plant that started up in 2014 added about 25,000 barrels a day of hydroprocessed lubricant base stock. Offshore, Anchor is a semisubmersible production unit in about 5,000 feet of water, some 140 miles off Louisiana, tied back to seven subsea wells designed for 20,000 psi. Between them these sites cover almost every classified-area situation a phone is likely to meet.
The area classification decides whether a device may be carried at all. After that, the site decides how it is used, and the three Chevron environments in the United States put very different loads on a phone.
A Permian lease operator drives from pad to pad and spends much of the shift outside any building. The 4,000 mAh battery is specified to carry a working shift, and four-constellation GNSS keeps a lone worker locatable where cellular coverage is patchy.
Reports of the spring 2025 Pascagoula turnaround described work on the crude units, vacuum distillation and jet fuel hydrotreating, with outside contractors supplying labour and logistics. A handset that Android Enterprise can enrol, restrict and wipe in minutes suits a workforce that changes every few weeks.
Anchor uses an all-electric production unit and carries a capped number of people on board. IP68 sealing and a camera that records the defect before the maintenance request goes ashore matter more there than any feature list.
US plants are mostly specified as Class I Division 1 or 2, while IECEx and ATEX work in zones. The IS-04Z1 is designed for Zone 1 and Zone 21, with NEC 500 listing in progress, so ask each site for its area classification drawing rather than assuming either.
We have not verified any Chevron contractor-registration programme and will not invent one. What can be said is how equipment approval normally runs at a US operator of this size.
OSHA requires equipment in a classified location to be approved, so the first question is which NRTL mark is on the label and what class, division and group it covers. The IS-04Z1 certification is in progress, so today the answer is a schedule, not a certificate.
Ask the site’s procurement and HSE teams what they require beyond the certificate: a technical review, a management-of-change record, or an entry in an approved-equipment list. These differ between refinery, upstream and offshore.
An Ex-certified unit cannot be opened by a general repair shop. Agree before purchase who services it, where spares sit and which team administers the Android Enterprise console.
No. It is pre-launch, certification is in progress and SAMS has no supply relationship, pilot or approval from Chevron. This page describes what Chevron’s teams would reasonably ask for and what the device is designed for.
Most refinery process areas are group IIA (Group D), but hydrogen in hydroprocessing units is group IIC, which is why the design target is Ex ib IIC rather than IIA or IIB. The site’s own area classification documents are the authority, not this page.
The design target is the same, Zone 1 and Zone 21 with NEC 500 Class I Division 1 in progress. The practical differences are the enrolment profile, whether platform Wi-Fi is available and who services units that fail.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for United States. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
Tell us the zone, gas group and operator. We will send the datasheet and the certification schedule for your market.
