Who we are

The only Saudi NACE-qualified wellhead provider.

IWS delivers specialist welding for the oilfield — wellhead installation, workover, NACE-compliant welding and PWHT — to a documented, code-compliant standard operators can verify. Our methodology was developed and qualified together with a major operator's technical organization to meet sour-service requirements, and it passed every qualifying test.

About IWS
What we do

Specialist welding — with wellhead installation at the core.

Our core discipline is specialist, code-compliant welding — wellhead installation, workovers, repair and recovery, NACE welding and PWHT, cold cutting and hot tapping. Every job, the same documented standard.

Wellhead installation

Complete wellhead and casing-head installation with pressure control integrity assured at every stage, performed by experienced technicians.

Code-compliant welding

Casing-head welding using the IWS methodology — chart-recorded preheat and inter-pass temperatures that meet ASME, API and ISO requirements.

Testing & integrity

Gas testing and follow-up activity that begins sooner — localized heating leaves equipment cool, returning the wellhead to service faster without cutting corners.

Onshore drilling rig site
Onshore & offshore

From desert rig sites to offshore platforms.

Wherever the well is, the standard travels with us. IWS crews work across onshore fields, offshore platforms and unconventional developments — bringing the same qualified procedures, documentation and safety discipline to every location.
