Oil & Gas Field Services
Emergency Oilfield Repairs, ASME R-Stamp Welding, and Certified Vessel Repairs
Built for Emergency Response and Certified Repairs
When production equipment fails in the field, delays cost money and shortcuts create risk. DSI Field Services delivers oil and gas field services, emergency oilfield repairs, and R-Stamp welding designed to restore operations safely, quickly, and correctly.
Operating directly in active oil and gas producing regions, our field services team provides rapid-response welding, certified vessel repairs, and shop-built or field-installed rebuilds that keep critical production systems online.
Emergency Oilfield Repairs Cannot Be Guesswork
Oil and gas field operations face constant pressure:
- Production equipment failures
- Certified vessels requiring immediate repair
- Leaks, pressure loss, or safety hazards
- Downtime that cannot wait for engineering delays
Too often, emergency oilfield repairs are treated like standard field welding, putting certifications, safety, and long-term reliability at risk.
Experienced Field Services, Not Temporary Fixes
DSI Field Services is led by professionals with deep experience in oilfield operations, industrial welding, and regulated repair environments. Our crews understand that field services are about more than welding. They require safety discipline, certification knowledge, and documentation that protects producers long after the repair is complete.
From middle-of-the-night callouts to planned rebuilds, DSI responds with the expertise required for high-risk oil and gas environments.
A Proven Process for Emergency and Certified Repairs
Four steps that protect the asset, the certification, and the people around it.
Rapid Response and Safety Control
We mobilize quickly, assess gas exposure, pressure conditions, and lockout and tagout requirements, and establish a safe work zone before repairs begin.
R-Stamp vs. Standard Repair Evaluation
DSI determines whether work requires ASME R-Stamp welding or standard field welding, protecting vessel certifications and operating pressure ratings.
Certified Execution and Documentation
R-Stamp repairs include full traceability, inspection hold points, non-destructive testing, and National Board documentation.
Reliable Return to Service
Repairs are completed to original or better standards, reducing repeat failures and unplanned downtime.

These services are delivered directly in active production environments, where safety, speed, and accuracy matter most.
Certified Vessel Repairs Protect Safety and Compliance
R-Stamp welding is not optional when repairing ASME certified vessels. Improper repairs can:
- Void vessel certification
- Reduce allowable operating pressure
- Create regulatory and safety exposure
- Lead to leaks, fires, or catastrophic failures
DSI Field Services is National Board accredited to perform R-Stamp welding repairs, which means:
- Certified welders and procedures
- Full repair traceability
- Inspection and NDE verification
- Compliance with original construction standards
Emergency Repairs Done Right the First Time
Producers rely on DSI Field Services because we:
- Restore operations quickly during emergencies
- Preserve vessel certifications and compliance
- Reduce repeat failures and long-term risk
- Deliver repairs that stand up to real field conditions
Emergency oilfield repairs should stabilize operations, not create the next failure.
Part of a Larger Oil & Gas Team
Field Services is the fifth piece of DSI’s oil and gas scope. The same company handles the electrical, controls, panels, and fabrication around it, so a repair can turn into a permanent fix instead of another callout.
