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 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. An ATEX and IECEx mobile phone distributor in Permian Basin would carry the IS-04Z1 to these buyers once certification completes.
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.
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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

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 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.
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.
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.
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 Permian Basin. The Permian covers a very large area of West Texas and south-east New Mexico, with big producers and service companies, some with international operations. Reviewers who work across borders may ask for dual ATEX and IECEx evidence. This is a certification route in progress for the IS-04Z1; no certificate has been issued.
A distributor for Permian Basin would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
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.
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 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.
