Operator change
The block passed from Chevron's Indonesian subsidiary to PT Pertamina Hulu Rokan in 2021, after about 70 years, so procurement follows Pertamina group processes.
Pekanbaru is the capital of Riau province on Sumatra and the regional base for the Rokan block, a 6,220 square kilometre oil area including the Minas, Duri and Bekasap fields. The previous operator drilled 16,023 wells across four blocks, including the Rokan block and the Coastal Plain Pekanbaru block, so a very dense network of wellheads, flowlines and facilities exists around the city. Distribution partners for Pekanbaru and the Rokan block, Riau are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Pekanbaru and the Rokan block, Riau 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.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Pekanbaru Oil Field. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
The block passed from Chevron's Indonesian subsidiary to PT Pertamina Hulu Rokan in 2021, after about 70 years, so procurement follows Pertamina group processes.
Pekanbaru has a tropical rainforest climate with rain in every month.
The Duri field, discovered in 1941 and in production from 1954, covers 67.28 sq km in Riau and has produced more than 2.75 billion barrels, making it one of Indonesia's largest and most productive fields.
Duri's thick crude is produced with steamflood enhanced oil recovery, introduced successfully by 1985, which lifted output to about 302 thousand barrels a day by 1995 and means hot steam systems run beside oil handling.
Indonesian is the official language in Pekanbaru, while Minangkabau is widely used in markets and daily business, and Riau Malay and Javanese are also commonly spoken, so site teams are often multilingual.
Pertamina Hulu Rokan now runs the Rokan block, which also includes the giant Minas field, where production began in April 1952, so one operator oversees several large mature fields around Pekanbaru.
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 Pekanbaru and the Rokan block, Riau. Because work at a mature field is mostly maintenance of existing facilities, rounds cover many dispersed wellheads, flowlines and gathering stations. A handheld designed for intrinsic safety could carry checklists and photographs between sites, once certified and accepted by the operator.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Pekanbaru and the Rokan block, Riau 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.
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.
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.
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.
Likely candidates are gathering stations, wellheads and flowlines, oil treatment and storage, steam generation and power facilities. 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 Pekanbaru and the Rokan block, Riau.
Typical areas include wellheads, flowlines, gathering stations, tank farms, pump stations and loading facilities, where flammable vapour can be released. The operator sets the zones, so confirm the classification for each facility rather than assuming one rule for the whole field.
The first road linking Pekanbaru with Dumai was built for the oilfield, and roads and a pipeline connect the Duri area to the Dumai port. Plan for customs clearance in Indonesia and site gate checks on electronics, and confirm lead times and import rules with your freight agent.
No, Pekanbaru is the regional support city for the block. Hazardous areas are in the field facilities, such as gathering stations and treatment plants. Office and workshop areas usually follow normal rules. Ask the operator which areas are classified.
