Beyond routine casing-head installation and welding, IWS has delivered a series of benchmark jobs — sour-service welds, rig-site installations and remedial repairs that raised the bar for what can be qualified in the field. Each is backed by testing and documentation operators can verify.
Installation and welding of an 18-5/8″ 4130 casing head onto J-55 casing on a sour-service gas well, completed to full NACE compliance in the field rather than in a workshop.
A benchmark for the company: among the first rig-site casing-head installations IWS delivered to full NACE compliance, establishing a repeatable field procedure for sour-service wells.
Because offshore gas fields require NACE compliance, IWS is relied on as the sole provider for this scope — with four casing-head installations and three workover / wellhead-repair campaigns delivered offshore to date.
A position earned on capability: IWS is the provider operators turn to when the offshore scope demands verified sour-service welding.
Two complete workover jobs delivered in partnership with a specialist hot-tapping contractor — IWS providing the workover welding services alongside the hot-tapping scope.
Evidence of IWS integrating cleanly into complex, multi-discipline live-well operations without compromising weld integrity or schedule.
Butt weld of a 14″ 95-HC pipe for an offshore well, verified for NACE compliance through both material testing and a 30-day NACE test.
A landmark qualification for IWS — to the best of our knowledge among the first successful NACE-compliant welds of this pipe grade, proven by full 30-day NACE testing rather than asserted.
Butt weld of a 14″ 95-HS re-stubbing at an onshore gas well, allowing the well to be completed rather than abandoned.
A benchmark rig-site qualification of this pipe grade for IWS — and a direct commercial saving, turning a would-be abandonment into a completed producer.
TIG welding of four separate 4130 plugs within a 4130 spool on offshore wells, restoring wellhead equipment in place.
A benchmark remedial capability for IWS: NACE-compliant repair of 4130 wellhead equipment carried out at the rig site rather than requiring workshop return or replacement.
Notes: Field names, exact dimensions and proprietary procedure details are omitted out of respect for our clients and their confidentiality. Where a job is described as a benchmark or among the first of its kind, this reflects IWS's own experience and records; supporting test reports and documentation are available to qualified operators on request.
These are the jobs IWS is built for. Talk to us about your next wellhead, workover or repair campaign.
