Hazardous Area Smartphone in Permian Basin
The Permian Basin covers more than 86,000 square miles of West Texas and south-east New Mexico and is the highest-producing oil field in the United States. The Permian Basin is about 250 miles wide and 300 miles long, spans West Texas and southeastern New Mexico and is made up of more than 7,000 fields. This page explains what to look for in a hazardous area smartphone for Permian Basin, and where the IS-04Z1 stands against that list today.

WherePermian Basin
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Permian 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.

Site conditions at Permian Basin: what wears and what limits equipment
Environment
The climate is hot and arid, and sites are spread over long distances, so vehicle-based access is normal.

More about Permian Basin that matters for portable equipment
Permian Basin: industry on the ground
The wider Permian Basin accounts for nearly 40 percent of United States oil production and nearly 15 percent of its natural gas, according to figures cited by the Texas Railroad Commission.
Permian Basin: background
The first commercial well in the basin came in at the Westbrook Field in Mitchell County in 1921, at a depth of about 2,500 feet.
Permian Basin: industry on the ground
The basin averaged about 4.2 million barrels of crude a day in 2019, making it the highest-producing oil field in the United States.
Permian Basin: who works there
Midland, Odessa and San Angelo serve as headquarters for much of the basin's oil production activity, so most contractors and service firms are based there.
The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Permian Basin. Classified areas here include drilling rigs, wellsites, tank batteries, compressor stations and gas processing plants. Producers such as Diamondback Energy and ExxonMobil, and the plant owners, classify their own sites. The Railroad Commission of Texas regulates oil and gas, but SAMS plays no role in classification.

Specifying a hazardous area smartphone for Permian 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 · Permian Basin
Frequently asked questions
Can we buy a hazardous area smartphone in Permian 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 a hazardous area smartphone in Permian 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.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
Which areas at Permian Basin would use it?
Likely candidates are drilling rigs, wellsites and tank batteries, compressor stations, gas processing plants. 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.
How large is the Permian Basin for site planning?
It covers roughly 86,000 square miles across West Texas and New Mexico, so travel between sites can be long. Plan around the main service hubs of Midland and Odessa, and confirm the exact location and gate rules for each facility.
What hazardous areas are typical in Permian oil and gas operations?
Wellpads, tank batteries, gas processing plants and compressor stations can all contain flammable gas and vapour. The operator classifies each location, and you should obtain the area drawings and approval requirements before taking any device there.
Do Permian operators set their own rules for phones in classified areas?
Yes, producers and service companies normally set their own equipment requirements. The Railroad Commission of Texas regulates oil and gas, but it does not approve handsets. The IS-04Z1 has no certificate yet. Confirm requirements with the site operator before any field trial.
