Environment
The climate is hot and arid, and sites are spread over long distances, so vehicle-based access is normal.
Today the basin is developed mainly through horizontal wells that target several stacked formations from one surface location, which concentrates activity on large multi-well pads. Zone 1 work arises at drilling rigs, wellsites, tank batteries, compressor stations and gas plants. Distribution partners for Permian Basin are being identified ahead of the Q4 2026 launch of the IS-04Z1.
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.
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 |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |

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 climate is hot and arid, and sites are spread over long distances, so vehicle-based access is normal.
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.
Midland, Odessa and San Angelo serve as headquarters for much of the basin's oil production activity, so most contractors and service firms are based there.
The basin is also a major source of potash, with room-and-pillar mines in Lea and Eddy counties, New Mexico, producing rock salt as a by-product.
The basin has three main parts: the Midland Basin to the east, the Delaware Basin to the west and the Central Basin Platform between them, covering about 86,000 square miles.
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.
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Permian Basin. Permian crews say explosion-proof for any gear approved near rigs, wellsites, tank batteries, compressor stations and gas plants. The real concepts are flameproof Ex d and intrinsic safety, and they behave differently. The IS-04Z1 is designed for intrinsic safety, targeting an Ex ib marking, not a flameproof enclosure.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Permian Basin. 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.
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.
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
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.
