Fields
Drilling shifted west as eastern fields such as East Texas, discovered in 1930, declined. The Permian Basin now dominates onshore output.
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. 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. Distribution partners for Texas oil and gas fields are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP rating for dust and water | IP68 design |
| Fleet management | EMM and MDM support | Android 16 with EMM and MDM |
| Explosion protection | A separate certificate and marking | In progress; not issued |
| Where it applies | Texas oil and gas fields: Compressor stations, Gas processing plants, Wellsites and tank batteries | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Texas Oil Fields. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.

The Railroad Commission of Texas oversees oil and gas exploration, production and transport, including hydrogen sulphide safety.
The Railroad Commission of Texas regulates the oil and gas industry, gas utilities, pipeline safety and LPG safety, and was created by the legislature in 1891.
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.
Thirty refineries operating in January 2019 made up 31 percent of national refining capacity, so oilfield and refinery work is closely linked.
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.
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Texas oil and gas fields. Texas producers and field service contractors run mixed fleets across many leases. EMM or MDM enrolment would let a contractor apply each client's policy to the IS-04Z1. Charging takes place in safe areas such as vehicles and yards, and offline operation should be tested for remote leases.
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.
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
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.
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
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.
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.
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.
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.
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.
