Regulation
The Railroad Commission of Texas oversees oil and gas exploration, production and transport, including hydrogen sulphide safety.
The Commission keeps about 132 million pages of well history documents, from drilling permits onward, and publishes monthly production data by county. Zone 1 work arises at wellsites, tank batteries, compressor stations and gas plants. This page explains what to look for in an IECEx smartphone for Texas oil and gas fields, 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 Texas oil and gas fields: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
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. 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 Texas Oil Fields. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The companies on site and the hazardous-area types a handset is likely to meet there.

Texas produced about 41 per cent of US crude in 2019 and had 30 refineries holding 31 per cent of US refining capacity in January 2019.
Texas hosts the headquarters of several major oil companies and many of the world's largest oilfield services firms, so decision makers are often close to the field.
The Permian Basin of West Texas alone supplies nearly 40 percent of US oil production, which explains why Midland and Odessa dominate equipment demand.
In May 2026 operators reported production from 156,120 oil wells and 84,661 gas wells, with statewide crude output averaging about 4.18 million barrels a day.
The Railroad Commission of Texas regulates the oil and gas industry, gas utilities, pipeline safety and LPG safety, and was created by the legislature in 1891.
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 Texas oil and gas fields. Texas producers and their service contractors with overseas operations may already use IECEx records elsewhere. A certificate of conformity and schedule of conditions would be the documents to review. For the IS-04Z1 these are targets, not held certificates, as the product remains pre-launch.
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.
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined 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 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.
Operators reported 156,120 oil wells and 84,661 gas wells in May 2026. That scale means field crews are widely dispersed, so reliable communication and battery life matter as much as location.
No, conditions differ widely: the Gulf Coast is humid and hurricane-exposed, West Texas is hot, dry and dusty, and parts of the state see winter frost. Match specifications to the region where the equipment will be used.
The Railroad Commission of Texas oversees oil and gas exploration, production and transport, including hydrogen sulphide safety. It does not certify phones. Equipment requirements generally come from producers and contractors, and the IS-04Z1 holds no certificate yet. Confirm requirements with the site operator.
