ATEX and IECEx Mobile Phone in Texas Oil Fields
Texas is the largest US crude oil producer, with onshore fields concentrated in the Permian Basin in the west and the historic East Texas field. Zone 1 work arises at wellsites, tank batteries, compressor stations and gas plants. If you are specifying an ATEX and IECEx mobile phone for Texas oil and gas fields, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Fields
Drilling shifted west as eastern fields such as East Texas, discovered in 1930, declined. The Permian Basin now dominates onshore output.
Field notes · Texas oil and gas fields
More about Texas oil and gas fields that matters for portable equipment
Texas oil and gas fields: infrastructure
The Commission keeps about 132 million pages of well history documents, from drilling permits onward, and publishes monthly production data by county.
Texas oil and gas fields: who works there
Texas hosts the headquarters of several major oil companies and many of the world's largest oilfield services firms, so decision makers are often close to the field.
Texas oil and gas fields: industry on the ground
The Permian Basin of West Texas alone supplies nearly 40 percent of US oil production, which explains why Midland and Odessa dominate equipment demand.
Texas oil and gas fields: industry on the ground
In May 2026 operators reported production from 156,120 oil wells and 84,661 gas wells, with statewide crude output averaging about 4.18 million barrels a day.
The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Texas oil and gas fields. Texas oil and gas work spans the Permian Basin and historic fields such as East Texas, with producers that sometimes work abroad too. A reviewer may look for dual ATEX and IECEx evidence to reuse one record internationally. The IS-04Z1 certification is in progress and no certificate has been issued.

Specifying an ATEX and IECEx mobile phone for Texas Oil Fields
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 · Texas Oil Fields
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in Texas Oil Fields today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an ATEX and IECEx mobile phone in Texas Oil Fields 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.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Which areas at Texas oil and gas fields would use it?
Likely candidates are wellsites and tank batteries, drilling rigs, 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 many oil wells are there in Texas?
Operators reported 156,120 oil wells and 84,661 gas wells in May 2026. That scale means field crews are widely dispersed, so reliable communication and battery life matter as much as location.
Are Texas oilfield conditions the same everywhere?
No, conditions differ widely: the Gulf Coast is humid and hurricane-exposed, West Texas is hot, dry and dusty, and parts of the state see winter frost. Match specifications to the region where the equipment will be used.
Which body regulates oil and gas operations in Texas?
The Railroad Commission of Texas oversees oil and gas exploration, production and transport, including hydrogen sulphide safety. It does not certify phones. Equipment requirements generally come from producers and contractors, and the IS-04Z1 holds no certificate yet. Confirm requirements with the site operator.
