Pekanbaru and the Rokan block, Riau: industry on the ground
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.
Pekanbaru and the Rokan block, Riau: who works there
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.

The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Pekanbaru and the Rokan block, Riau. Gathering stations, wellheads, oil treatment and steam facilities mix hazards. Explosion-proof is a loose term. Flameproof Ex d suits fixed motors and panels, while a handheld carried around wellheads and flowlines relies on intrinsic safety. The operator's classification decides where each applies.

Questions · Pekanbaru Oil Field
Frequently asked questions
Can we buy an explosion proof smartphone in Pekanbaru Oil Field today?
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.
What does an explosion proof smartphone in Pekanbaru Oil Field cost?
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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Which areas at Pekanbaru and the Rokan block, Riau would use it?
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.
Is intrinsically safe the same as explosion proof?
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Why does steamflood production matter for equipment used at Duri?
Steamflood means hot steam lines and wells operate close to oil and gas handling, so surface temperatures can be higher than at conventional wells. Handheld devices should respect the site's temperature limits and classification, so ask the operator for its rules on portable electronics.
Which company operates the large oil fields around Pekanbaru today?
The Rokan block, including the Minas and Duri fields, has been run by Pertamina Hulu Rokan since August 2021. Contractors and suppliers typically register through Pertamina's vendor processes and follow the site's own induction and permit rules, so confirm current requirements.
Who approves suppliers for the Rokan block?
Suppliers are normally approved by the operator and its contractors, following Pertamina group processes since the 2021 operator change. Ask PT Pertamina Hulu Rokan about current registration requirements before offering any equipment. Confirm with the site operator.
