Roustabout crews, hydrovac, pressure testing and welding for oil and gas operators, out of Williston, North Dakota.
Setting equipment, digging safely around lines, testing, welding, coating and clean-up. One crew, one call.
Williams Engineering Services works for oil and gas operators in North Dakota and other US markets, from our shop on Bassett Lane in Williston.
We set equipment, dig safely around buried lines, test lines and valves, weld, coat and clean up. One call covers most of what a production site needs.



Paper tickets get lost, and test reports get questioned months later. Ours don't. Every field ticket and test certificate is signed on location, photographed, and locked so nobody can change it afterwards, including us.
Your company man signs the ticket or certificate on our tech's phone. Not on location? You approve it later from a link.
The record, photos and signature are locked together with the time, so nobody can change them later.
Tested valves and lines carry a tag that links straight to their certificate.
Your office or an inspector confirms the record in their own browser. No calls, no chasing.
Live from the Williams record chain, checked in your browser just now.
The crew completes and signs a job safety analysis before any work starts. Anyone can stop the job.
Saltwater, oil and spill clean-up on and off location, with disposal only at approved facilities.
We pressure test every installation when it's finished, for a safe startup.
We track every crew member's safety cards, like H2S and SafeLand, and renew them before they run out.
Send the scope and the location. We'll come back with a bid you can sign on your phone.
