PDO: background
PDO's name was shortened to Petroleum Development (Oman) in 1951 after the Dhofar concession lapsed, and the company later operated as Petroleum Development Oman from 1967.

Explosion-Proof Smartphone for PDO
Petroleum Development Oman (PDO) is Oman's main oil and gas producer, operating a concession of about 90,000 square kilometres. A 276 kilometre pipeline from the interior fields to the coast was laid in the 1960s, ending at an industrial complex, tank farm and marine terminal at Mina al Fahal near Muscat. If you are specifying an explosion proof smartphone for PDO, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

WherePDO
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for PDO: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Supplier approval · PDO
Becoming an approved supplier to PDO
Joint Supplier Registration System (JSRS) certification from the Ministry of Energy and Minerals is a prerequisite before suppliers can be qualified by PDO; PDO's website has a Vendor Corner for registration. 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.
Field notes · PDO
More about PDO that matters for portable equipment
PDO: industry on the ground
PDO delivers the majority of Oman's crude oil production and natural gas supply, making it the dominant operator for onshore exploration and production in the Sultanate.
PDO: background
The first commercially significant oil find came at Yibal in April 1962, followed by Natih in 1963 and Fahud, and the first export cargo left Oman on 27 July 1967.
PDO: rules and approvals
Supplier guides stress that PDO assesses safety, quality and local value creation when approving vendors, so contractors working in its fields should expect safety induction and local content questions.
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 PDO. On wellheads, flowlines and gathering stations, explosion-proof is often used loosely. In practice it covers distinct concepts: flameproof Ex d enclosures for heavy fixed equipment, and intrinsic safety for low-energy instruments and handhelds. A phone is a handheld, so intrinsic safety is the relevant concept, and the target marking is II 2 G Ex ib IIC T4.

Specifying an explosion proof smartphone for PDO
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · PDO
Frequently asked questions
Can PDO buy the IS-04Z1 today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an explosion proof smartphone for PDO 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.
How does PDO approve suppliers?
Joint Supplier Registration System (JSRS) certification from the Ministry of Energy and Minerals is a prerequisite before suppliers can be qualified by PDO; PDO's website has a Vendor Corner for registration.
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.
Where does PDO work involve Zone 1 areas?
Typically at wellsites, production stations and gas processing plants in the interior concession area, and at the Mina al Fahal coastal terminal and tank farm. The operator issues the hazardous-area classification for each facility, so ask for the zone, gas group and temperature class before selecting equipment.
Is PDO the only major operator in Oman?
PDO is the largest onshore exploration and production company and delivers most of Oman's crude oil and gas supply, but other operators and OQ's refining and petrochemical businesses also run hazardous-area sites. Each organisation sets its own supplier and equipment rules, so confirm with the one that controls your site.
How would the phone cope with desert heat on remote concession sites?
The IS-04Z1 is IP68 rated against dust and water and carries a 4,000 mAh battery, but ambient temperature limits will come from the final certificate and datasheet. Do not assume operation beyond the stated temperature range. IP68 is not explosion protection. Check the temperature class against the area before use.
