Role
Midland is described as a major centre of US oil and natural gas production, and Odessa's economy has been driven mainly by the oil industry. Midland International Air and Space Port serves both cities.
Midland and Odessa are neighbouring West Texas cities that serve as the main service and headquarters base for the Permian Basin. Zone 1 work arises in the surrounding fields at wellsites, tank batteries, compressor stations and gas plants rather than in the cities themselves. This page explains what to look for in an ATEX and IECEx smartphone for Midland and Odessa, Texas, 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 Midland and Odessa, Texas: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Midland Odessa. 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.
Midland is described as a major centre of US oil and natural gas production, and Odessa's economy has been driven mainly by the oil industry. Midland International Air and Space Port serves both cities.
Oilfield service firms such as Halliburton (about 1,400 staff in Odessa) and Baker Hughes are major local employers.
The shale boom of the early 2010s revived the area after the 1980s oil bust, with manufacturing, transport and construction firms largely serving the energy industry.
Midland International Air and Space Port is located between the two cities and gives direct access for visiting engineers, while general aviation uses Midland Airpark.
The Midland metro area had about 170,000 residents and the combined Midland-Odessa area about 340,000 at the 2020 census, and Midland recorded the lowest US unemployment rate in 2014 at 2.3 percent.
Midland has a hot semi-arid climate with about 13.5 inches of rain a year, highs above 90 degrees Fahrenheit on roughly 115 afternoons and 100 degrees or more on about 24.
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 Midland and Odessa, Texas. Midland and Odessa are the service and headquarters base for the Permian, and the classified work happens in the surrounding fields. Producers and service contractors with international operations may ask for dual ATEX and IECEx evidence so the same device record can be reused abroad. The IS-04Z1 certificates are in progress and not issued.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
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.
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.
Midland International Air and Space Port sits between the two cities and is the closest airport; most visitors connect through a larger Texas hub. Allow for long road transfers because the Permian Basin covers about 86,000 square miles.
Oilfield sites are spread over a large area with wellpads, tank batteries and gas processing plants, so lone-worker and coverage requirements often matter as much as area classification. Confirm classified zones and approval rules with each operator.
Producers and service contractors usually buy through their own procurement or field contractors, so the buyer may be a service company rather than the operator. The IS-04Z1 is pre-launch with no certificate. Ask the relevant site operator which approvals apply to contractor devices.
