Mature field
Duri has been steamflooded since 1985 and is described as one of the world's largest steamflood developments, so work is mostly maintenance of existing facilities.
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. PT Pertamina Hulu Rokan has operated it since 9 August 2021. Distribution partners for Pekanbaru and the Rokan block, Riau are being identified ahead of the Q4 2026 launch of the IS-04Z1.

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.
Duri has been steamflooded since 1985 and is described as one of the world's largest steamflood developments, so work is mostly maintenance of existing facilities.
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.
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.
A pipeline from Duri to the Dumai export terminal was completed by 1958, and the first road linking Pekanbaru with Dumai was built by the operator, forming the logistics spine of the Riau oil region.
Chevron Pacific Indonesia handed over the Rokan block to Pertamina Hulu Rokan on 8 August 2021 after 97 years in Indonesia and more than 12 billion barrels of oil produced from central Sumatra.
The Duri area developed as a residential hub for the workforce that supports production, with roads, electricity networks and storage tanks built alongside the field.
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Pekanbaru and the Rokan block, Riau. After the 2021 operator change, contractors who served the field under its previous operator work alongside Pertamina group teams. IECEx is a neutral reference for both. A certificate of conformity and schedule of conditions would be reviewed; for the IS-04Z1 they are targets only.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Pekanbaru and the Rokan block, Riau. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
