Call Before You Dig: One-Call Locates on Oilfield Locations
Every oilfield location sits on top of buried lines: flowlines, gathering lines, water lines, power cable, and fiber. A new well pad, a pipeline tie-in, a rig move, or a simple grading pass can put a bucket through any of them in seconds. The one-call process exists to keep that from happening, and it works when crews treat a locate request as a required step, not paperwork.
The one-call system and 811
811 is the national Call Before You Dig number. Dial it from anywhere in the United States and the call routes to the one-call center that serves your county. One call replaces the impossible job of tracking down every operator with buried facilities on your own.
Every state has a one-call law, and nearly all of them route through 811. Those laws say the same thing: anyone who excavates must request locates before digging and wait out the response window. That includes oilfield work. A pipeline tie-in, a waterline repair, a new access road, even fence posts on a lease is excavation under the law. The requirement does not go away on private lease land or inside a fenced location, and operators usually write it into their standards and contractor contracts as well.
A locate request is not a permit and does not clear you to dig. It starts the marking process. The digging still has to meet the operator's rules.
What a locate request starts
When you call in a request, the one-call center opens a ticket. The ticket carries a number, the work location, the date you plan to dig, and a contact for the crew. Keep that number; it is the record of the request if anything goes wrong.
The center forwards the ticket to every member operator with buried facilities in the area: pipeline companies, electric utilities, water districts, and communications providers. Each checks its records and decides whether to mark. If the facility is in your work area, an operator sends a locator or survey crew. Do not guess where lines are or trust the memory of last season's job.
State law sets the response window, commonly a couple of business days. The clock starts when the ticket is filed, not when you decide to start. Marks come as paint on the ground and flags on stakes, and the color says what is below: red for electric, yellow for gas and oil, orange for communications, blue for water, green for sewer, white for proposed excavation, and pink for survey. Learn the code and teach it to the crew.
Locates do not last forever. If the job is delayed past the response window, if the marks get buried or driven over, or if the work area changes, file again. A faded set of paint lines is not a locate.
Excavation near buried lines
Treat the marks as the center line of the facility, not the edge of the danger zone. Keep mechanical equipment out of the tolerance zone: no bucket teeth, no backhoe, no dozer blade inside the marked width. Inside that zone, hand tools only, and even then carefully. Most strikes happen in the last foot, with a shovel or a bucket corner at the end of a careful pass.
When the excavation reaches a line, take your time. Keep the pipe supported so it does not sag or bend, and keep the bedding that holds it. Protect an exposed line from impact, from falling dirt, and from equipment swinging overhead. Do not hang anything off it or use it as a step. When you backfill, pad around the line with clean fill before the heavy material goes in, and keep rocks away from the pipe.
The same rules apply to the ground work around a job, not just the trench. Rig moves, pad construction, and workover setup all involve grading and excavation near lines that may not be on the surface drawing, so prep work counts as digging too. See the guides on rig move planning and workover rig operations for how site prep fits the job plan.
Strikes happen: what follows
Even with a locate and a careful crew, lines get hit. What matters is the next few minutes. Stop the equipment immediately. Do not pull the line clear, bend it back, or bury it and move on. A damaged line that is reburied is a hazard no one can see, and on a gas or oil line it is a serious one.
Control the immediate hazard: keep people and equipment away, and shut down anything that could ignite a release. Then report the strike to the facility operator and the one-call center. The operator decides how to respond and repair. Your job is to protect the scene, document what you can, and wait for direction.
Records separate a clean strike from a costly dispute. Keep the ticket number, the date and time of the hit, photos of the marks before the dig and the damage after, and a log of who was on site and what equipment was running. Those records help the operator find the cause and bill the right party, and they show your crew actually requested locates when a regulator or adjuster asks.
Building it into the work order
A locate request works best when it is part of the job from the start, not a phone call made from the cab on the way to the location. Put the locate on the work order: ticket number, filing date, response window, and expiry. The foreman checks for live marks before any equipment moves. Locate ticket numbers and dig permits belong on the work order, which is where software like OpsFlo keeps them alongside dispatch, approvals, and timesheets.
Treat the ticket as a document with a shelf life. If the job slips a week, re-file. If the scope changes and the trench moves, re-file. If a storm buries the flags, re-file. A current ticket is cheap; a strike on a stale one is not.
Digging near buried lines is part of the job for crews who do pad work, tie-ins, and maintenance. It sits alongside qualification-based tasks such as operator qualification for pipeline work, and it shows up again in precommissioning work, where excavation and backfill happen before a line goes into service. Build the same discipline into each phase: locate first, hand dig near the line, keep the paperwork.
