    Fluid from well workover

AER oilfield waste code.

Alberta Energy Regulator oilfield waste code for the fluids left when a producing well is reworked or serviced.

Is Alberta WWOFLD hazardous waste?

Not from the code alone. Alberta WWOFLD is the AER oilfield-waste code for fluid from well workover. It fits only waste from the upstream facilities, wells or pipelines on that route. The code alone doesn't make the waste dangerous oilfield waste.

Dangerous oilfield waste stays on the AER route inside Alberta. It needs an Alberta hazardous-waste manifest only if it is exported from Alberta. Record the AER code in the oilfield waste information. A regulated export also needs the federal movement assessment, and a generic industrial category can't replace the AER code.

What does Alberta WWOFLD cover?

Single or mixed fluids returning to the surface during well servicing, workover or completion, including acid jobs. Use FRFLDH, FRFLDR or FRFLDW for fracturing. The code is tied to upstream oilfield origin. The actual composition and properties still decide whether the waste is dangerous and how to handle it.

When does fluid from well workover Alberta WWOFLD fall under Alberta WWOFLD?

CodeWhen it fits
WWOFLDThe waste comes from the AER upstream oilfield route and its material matches this stream.

Origin matters. Waste from an unrelated industrial activity doesn't become oilfield waste because its material has a similar name.
