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

Intrinsically Safe 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. 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. An intrinsically safe smartphone distributor in US shale oil operations would carry the IS-04Z1 to these buyers once certification completes.

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.
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.

More about US shale oil operations that matters for portable equipment
US shale oil operations: people and language
About two thirds of the world's active drilling rigs are in the United States and Canada, and many independent operators and contractors have shale expertise, so crews and service firms are plentiful.
US shale oil operations: geography and layout
Tight oil formations in the United States include the Bakken, Niobrara, Barnett and Eagle Ford shales, spread across several states and climates.
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.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In US shale oil operations. Shale field crews visit many wellsites and tank batteries, in both hot West Texas and cold North Dakota conditions. An intrinsically safe handheld is designed to be carried into Zone 1 areas for gauging records and photographs. Battery behaviour across that temperature spread should be evaluated, and certification must come first.
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 intrinsically safe smartphone in US Shale Oil Operations today?
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.
What does an intrinsically safe 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 does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is 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.
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.
