Bakken
Bakken output rose through horizontal drilling and hydraulic fracturing, with North Dakota and Montana passing 1 million barrels a day in April 2014.

Explosion-Proof Smartphone 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. 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. This page explains what to look for in an explosion proof smartphone for US shale oil operations, and where the IS-04Z1 stands against that list today.

WhereUS Shale Oil Operations
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for US shale oil operations: 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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

More about US shale oil operations that matters for portable equipment
US shale oil operations: infrastructure
Tight reservoirs typically need roughly 15 to 20 percent natural gas in the pore space to drive the oil, so oil wells commonly come with associated gas to handle.
US shale oil operations: projects and investment
Tight oil is light crude held in low-permeability formations and is produced with hydraulic fracturing and horizontal wells; at least 4,000 new shale wells came online in 2012 alone.
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: geography and layout
The Permian Basin alone is about 250 miles wide and 300 miles long, which shows how widely shale activity is spread.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In US shale oil operations. In shale country, explosion-proof is field shorthand for gear around drilling rigs, wellsites, tank batteries, compressor stations and gas gathering. The concepts differ: flameproof Ex d versus intrinsic safety. The IS-04Z1 is designed for intrinsic safety and targets an Ex ib marking.

Specifying an explosion proof smartphone for US Shale Oil Operations
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · US Shale Oil Operations
Frequently asked questions
Can we buy an explosion 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 explosion proof smartphone in US Shale Oil Operations cost?
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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
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.
Is intrinsically safe the same as explosion proof?
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.
Which shale basins matter most for handset demand?
The Permian dominates, followed by the Eagle Ford and Bakken, which together made up about 93 percent of US tight oil in 2023. Each has a different climate, from hot and dusty West Texas to very cold North Dakota.
Why does the shale industry change demand so quickly?
Activity follows oil prices and drilling schedules, with many independent operators adjusting programs quickly. Suppliers usually need flexible stock and fast service, and buyers should agree lead times in advance.
Do Permian and Bakken operators apply the same equipment rules?
Not necessarily. Producers and field service contractors generally set their own equipment requirements, and the states have separate regulators for oil and gas. The IS-04Z1 has no certificate yet. Confirm requirements with the site operator in each basin.
