Tengizchevroil: who works there
Chevron holds 50%, ExxonMobil 25% and KazMunayGas 20%, with a minority partner holding the remainder, so contractor standards are shaped by international majors as well as the national company.

Tengizchevroil is a joint venture developing the Tengiz and Korolevskoye fields in the Atyrau region of Kazakhstan. The joint venture was formed in April 1993, when the Kazakh government granted it exclusive 40-year development rights, so it is a long-established operation with mature site procedures. Buyers searching for an ATEX and IECEx smartphone supplier for Tengizchevroil can take the datasheet and the certification schedule for the IS-04Z1 now; supply follows certification.

How suppliers reach Tengizchevroil
TCO's procurement favours qualified Kazakhstani contractors (over 1,250 contracts awarded to local firms on the Future Growth Project); confirm current supplier requirements with TCO. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.

Tengizchevroil: projects and investment
Tengizchevroil completed the Future Growth Project-Wellhead Pressure Management Project in 2025, designed to add 260,000 barrels a day at full capacity and take total Tengiz output to roughly one million barrels of oil equivalent a day.
Tengizchevroil: industry on the ground
Output reached a record 27.1 million tonnes of oil in 2013 and about 30 million tonnes in 2019, showing a large continuous process operation with extensive classified areas.
Tengizchevroil: rules and approvals
Because the venture is operated for international partners, supplier access normally runs through its own approved-contractor and HSE induction process rather than a general national register; confirm current rules with its procurement team.
The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
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 Tengizchevroil. A Tengizchevroil reviewer would expect certificate evidence before a handheld enters the production plants at Tengiz, including the Third-Generation Plant. As a joint venture with international shareholders and many contractors, a dual ATEX and IECEx route lets one product answer both families of paperwork. The IS-04Z1 is in certification and no certificate has been issued.

Questions · Tengizchevroil
Frequently asked questions
Can Tengizchevroil buy the IS-04Z1 today?
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.
What does an ATEX and IECEx smartphone for Tengizchevroil 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 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
How does Tengizchevroil approve suppliers?
TCO's procurement favours qualified Kazakhstani contractors (over 1,250 contracts awarded to local firms on the Future Growth Project); confirm current supplier requirements with TCO.
How will SAMS supply Tengizchevroil?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
How does the climate near the north-eastern Caspian affect phones in the field?
Continental climates around the north Caspian typically bring very cold winters and hot, dusty summers. For handheld devices this means checking operating temperature range, battery behaviour in cold, and ingress protection against dust. Confirm the site's temperature limits with the operator.
Is Tengiz a sour-gas environment that affects mobile device selection?
Tengiz is a large Caspian oil field, and sour hydrocarbon handling is common in such operations, so gas-detection and hazardous-area discipline matter. Whether specific areas are classified Zone 1 or Zone 2 is decided per installation, so confirm each work area's classification with the operator.
Does Tengizchevroil favour local suppliers for equipment like this?
Its procurement is reported to favour qualified Kazakhstani contractors, with many contracts awarded to local firms on its Future Growth Project. A foreign manufacturer would normally work through local partners. Ask the company for current supplier requirements; the IS-04Z1 has no certificate yet and SAMS has appointed no distributor.
