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.

Ex-Proof Smartphone Distributor in US Shale Oil Operations
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. Distribution partners for US shale oil operations are being identified ahead of the Q4 2026 launch of the IS-04Z1.

WhereUS Shale Oil Operations
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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

More about US shale oil operations that matters for portable equipment
US shale oil operations: rules and approvals
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.
US shale oil operations: industry on the ground
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.
US shale oil operations: geography and layout
The Permian Basin alone is about 250 miles wide and 300 miles long, which shows how widely shale activity is spread.
US shale oil operations: industry on the ground
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.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In US shale oil operations. A marking check at a shale wellsite or gas gathering facility would compare zone, gas group and temperature class with the operator's classification. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, for Zone 1 gas. The operator decides what applies at each pad and facility.
The route · distribution
Distributing the IS-04Z1 in US Shale Oil Operations
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for US shale oil operations yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in US shale oil operations.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · US Shale Oil Operations
Frequently asked questions
Can we buy an Ex-proof smartphone in US Shale Oil Operations today?
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.
What does an Ex-proof smartphone in US Shale Oil Operations cost?
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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at US shale oil operations would use it?
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.
How do I become a SAMS distributor for US shale oil operations?
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.
How should I plan for the weather across shale regions?
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.
Do shale operations create different hazardous-area needs from refineries?
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.
How do hot and cold fields affect battery planning?
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.
