Fields
Drilling shifted west as eastern fields such as East Texas, discovered in 1930, declined. The Permian Basin now dominates onshore output.

ATEX and IECEx Smartphone Distributor 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. The Permian Basin of West Texas alone supplies nearly 40 percent of US oil production, which explains why Midland and Odessa dominate equipment demand. An ATEX and IECEx smartphone distributor in Texas oil and gas fields would carry the IS-04Z1 to these buyers once certification completes.

WhereTexas Oil Fields
Short answer. Texas oil and gas fields 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.
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.

Texas oil and gas fields: industry on the ground
Texas produced about 41 percent of national crude oil and 25 percent of national natural gas in 2019, and is the largest state producer of both.
Texas oil and gas fields: geography and layout
As wells in the east of the state depleted, drilling moved westward, and today the busiest activity is in West Texas and under the Gulf of Mexico.
Texas oil and gas fields: industry on the ground
Thirty refineries operating in January 2019 made up 31 percent of national refining capacity, so oilfield and refinery work is closely linked.
Texas oil and gas fields: background
The first major Spindletop well was drilled on 10 January 1901, and the East Texas Oil Field, found in 1930, is the largest and most prolific oil reservoir in the contiguous United States.
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.
The route · distribution
Distributing the IS-04Z1 in Texas Oil Fields
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Texas oil and gas fields. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in Texas oil and gas fields.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · Texas Oil Fields
Frequently asked questions
Can we buy an ATEX and IECEx smartphone in Texas Oil Fields 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 ATEX and IECEx smartphone 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.
How do I become a SAMS distributor for Texas oil and gas fields?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Texas oil and gas fields.
Which authority regulates oil and gas operations in Texas?
The Railroad Commission of Texas regulates oil and gas production, pipelines and LPG safety, while each operator sets its own electrical safety and equipment rules. For equipment approvals, ask the operator which marks and standards they accept.
Which hazardous-area system is common in Texas?
US sites commonly use the National Electrical Code, which includes both a Class and Division approach and a Zone approach, and equipment is typically tested by a recognised US laboratory. The operator's area classification is the deciding document.
Do older and newer Texas fields need different checks?
Classification is site-specific, whatever the field's age. A wellsite, tank battery, compressor station or gas plant each has its own classification and drawings. Compare the IS-04Z1 target marking against each, and ask the operator about permit rules. Certification is still in progress.
