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 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. 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. This page explains what to look for in an explosion proof smartphone for Permian Basin, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Permian Basin: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
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.
| 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 |
| Where it applies | Permian Basin: Drilling rigs, Wellsites and tank batteries, Compressor stations | 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.

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 climate is hot and arid, and sites are spread over long distances, so vehicle-based access is normal.
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.
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.
“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.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
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.
It covers roughly 86,000 square miles across West Texas and New Mexico, so travel between sites can be long. Plan around the main service hubs of Midland and Odessa, and confirm the exact location and gate rules for each facility.
Wellpads, tank batteries, gas processing plants and compressor stations can all contain flammable gas and vapour. The operator classifies each location, and you should obtain the area drawings and approval requirements before taking any device there.
Yes, producers and service companies normally set their own equipment requirements. The Railroad Commission of Texas regulates oil and gas, but it does not approve handsets. The IS-04Z1 has no certificate yet. Confirm requirements with the site operator before any field trial.
