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.
The companies on site and the hazardous-area types a handset is likely to meet there.
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.
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Pekanbaru and the Rokan block, Riau. Pekanbaru has a tropical rainforest climate with rain every month, so field devices meet heat, humidity and wet conditions. IP68 rates dust and water ingress. It does not provide explosion protection, which must be assessed against the zone where the device is used.
A distributor for Pekanbaru and the Rokan block, Riau would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are 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.
