Tatweer Petroleum works the Bahrain Field, which has produced oil since 1932, and the gas that comes with it. This page is for the HSE, wellsite and telecoms people who need an explosion proof mobile phone for Bahrain onshore field work and want to know what the IS-04Z1 is designed for in a brownfield wellfield. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · IECEx programme in progress
The Bahrain Field, also called the Awali Field after the district at its northern end, produced oil for decades before Tatweer took over operations in December 2009, according to trade press. That press has also reported well over a thousand new wells since then, a drilling programme into the deeper Khuff gas reservoir, and gas dehydration facilities. Bapco Energies lists Tatweer within its portfolio and has been reported as the owner; ask the operators for the current structure before assembling a vendor file.
A field this old mixes generations of equipment. Newer wellsites and gathering systems sit beside older installations whose area classification documents may have been revised several times, so a handset is checked against drawings of different ages.
Wellsites are spread across the field, so rounds are driven. A technician cannot return to a safe-area charging point between wells, which makes full-shift battery a design requirement; the 4,000 mAh cell is specified for it.
A leaking wellhead gland or a corroded flowline needs a coordinate more than a description. Four-constellation GNSS and the 50 MP camera together give that.
Older and newer installations carry classification documents of different dates. The engineering review will compare the certificate and its limits with whichever is current for the area.
A rig brings its classified area with it. Contractor crews on a campaign can be issued enrolled devices for its duration.
A field workforce mixes national and expatriate staff, so Arabic and English on one Android 16 build suits the shift. Photography at oil and gas sites runs on permit, and the camera policy can be pushed from the existing MDM console rather than left to individual users.
Khuff gas and associated gas may carry hydrogen sulphide, which is a toxic hazard handled by personal and fixed gas detection, not by a phone.
A production technician records readings, photographs a wellhead fault with its position, and reports to the field control room from one device.
A drilling crew works to a permit issued that morning. An enrolled handset carries the permit, the daily report and the contact directory.
An inspector moving between gas wells, dehydration units and the export line records observations against each asset with time and position.
The IS-04Z1 is pre-launch (Q4 2026) and no certificate has been issued; IECEx, ATEX, NEC 500 and BSMD work is in progress. SAMS has no relationship with Tatweer.
We found no separate published Tatweer supplier-registration scheme. Bapco Energies, in whose portfolio it is listed, runs a Supplier Portal and requires adherence to a Supplier Code of Conduct, and Bapco Upstream publishes tenders on the Bahrain Tender Board. Ask the operator's procurement and HSE teams which applies to a handset, who reviews it, and how they treat older and newer area documentation. The national route (BSMD, GSO and TRA) is on the Bahrain country page.
Trade press and the group's portfolio list Tatweer as a separate operating company within it. Check which entity is the buyer for the site you mean.
No, the certificate does not depend on site age. It affects the operator's review, which compares the certificate with whatever classification drawings exist for each area.
It is designed for it: IP68 sealing, a 4,000 mAh battery for a shift and GNSS for positions. Evaluation in safe areas comes first.
No. Gas detection is a separate certified safety system. The handset must not be an ignition source and should carry the call when an alarm sounds.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for Bahrain. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
Tell us the zone, gas group and operator. We will send the datasheet and the certification schedule for your market.
