Permian
The Permian is the highest-producing US oil field, at 4.2 million barrels a day in 2019, with Midland-based Diamondback among its operators.
US shale oil comes mainly from the Permian Basin in Texas and New Mexico and the Bakken in North Dakota. Zone 1 work arises at drilling rigs, wellsites, tank batteries, compressor stations and gas gathering. An IECEx mobile phone distributor in US shale oil operations would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. US shale oil operations 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.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in US Shale Oil Operations. 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 Permian is the highest-producing US oil field, at 4.2 million barrels a day in 2019, with Midland-based Diamondback among its operators.
Bakken output rose through horizontal drilling and hydraulic fracturing, with North Dakota and Montana passing 1 million barrels a day in April 2014.
Private ownership of subsurface mineral rights in the United States makes it easier to lease land for drilling, which has encouraged a large number of independent operators.
The Permian, Eagle Ford and Bakken together produced about 93 percent of US tight oil in 2023, and US output reached 13.2 million barrels a day.
The Permian Basin alone is about 250 miles wide and 300 miles long, which shows how widely shale activity is spread.
The Permian Basin supplied about 46 percent of US domestic oil in 2023, while other tight oil plays accounted for a further 22 percent, based on figures from the US Energy Information Administration and Enverus.
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In US shale oil operations. Shale operators and service companies with global operations may use IECEx records in other regions. For them a certificate of conformity and schedule of conditions would be the reference documents. For the IS-04Z1, IECEx is a target, and nothing has been issued while the product is pre-launch.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for US shale oil operations. 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 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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Likely candidates are drilling rigs, wellsites and tank batteries, compressor stations, gas gathering and processing. 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 US shale oil operations.
North Dakota has deep winter cold, West Texas has heat and dust, and the Gulf Coast side has humidity and hurricanes. Check a device's temperature, dust and water ratings against the specific region and season.
Wellpads, separators, tank batteries and compressors may contain flammable gas or vapour, and the operator defines classified areas. Operations are dispersed, so lone-worker safety and battery life are often as important as classification.
Fields are remote, with heat in West Texas and cold winters in North Dakota. Check the datasheet's temperature range once published, keep spare charged devices in safe areas, and trial the phone in your own climate. IP68 does not change battery behaviour at temperature extremes.
