Scale
The basin averaged 4.2 million barrels of crude a day in 2019 and has Midland and Delaware sub-basins separated by the Central Basin Platform.
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. Zone 1 work arises at drilling rigs, wellsites, tank batteries, compressor stations and gas plants. An Ex-proof smartphone distributor in Permian Basin would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Permian Basin 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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Permian Basin: Compressor stations, Gas processing plants, Drilling rigs | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Permian Basin. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
The basin averaged 4.2 million barrels of crude a day in 2019 and has Midland and Delaware sub-basins separated by the Central Basin Platform.
Diamondback Energy is based in Midland and focuses on the Permian. ExxonMobil acquired Pioneer Natural Resources, a large Midland Basin acreage holder, on 3 May 2024.
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.
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.
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.
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.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Permian Basin. At a compressor station or gas plant, a marking check would read zone, gas group and temperature class against the operator's classification. The IS-04Z1 target is II 2 G Ex ib IIC T4 for Zone 1 gas. The operator, not the device supplier, decides whether that marking is accepted at a specific facility.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Permian Basin yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service locally.
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.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
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.
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 Permian Basin.
Activity is very large and moves with oil prices, so service teams can be stretched. Book calibration, repair and training slots early, and keep spare units for field crews to avoid downtime.
The region is generally hot and dry in summer with dust, and cold snaps in winter. Look for dust-tight sealing, a wide operating temperature range and good battery behaviour, and verify details on the manufacturer's datasheet.
The climate is hot and arid and sites are spread out, so crews drive between them. Check battery behaviour in heat, keep chargers in vehicles or yards outside classified areas, and trial offline use where coverage is weak. IP68 helps with dust but is not explosion protection.
