Environment
The climate is hot and arid, and sites are spread over long distances, so vehicle-based access is normal.
Permian Basin · IECEx
IECEx Smartphone in Permian Basin
About 80 percent of the basin's estimated reserves lie at depths of less than 10,000 feet, which is a useful figure when judging drilling and well-site activity. Zone 1 work arises at drilling rigs, wellsites, tank batteries, compressor stations and gas plants. This page explains what to look for in an IECEx smartphone for Permian Basin, and where the IS-04Z1 stands against that list today.

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: geography and layout
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.
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.
The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Permian Basin. Large operators in the Permian, including those with global portfolios, may already use IECEx records in other regions. A certificate of conformity and schedule of conditions would be the documents to read. For the IS-04Z1 these are targets, and none has been issued while the product remains pre-launch.

- 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 an IECEx 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 an IECEx smartphone in Permian Basin cost?
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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
