For the second time in less than a month, crews responded to a fire at an oil well site near US 85 in Brighton.

The fire was reported just after 2 p.m. at 13448 Weld County Road 4 -- a site operated by Great Western Oil & Gas Co.

Two workers were on site when the fire broke out, but no one was injured according to Natalie Ridderbos, a spokesperson for Brighton Fire. There were no evacuations to nearby homes.

As of 5 p.m. , crews had two master streams in operation on the fire, and planned to let the oil burn out.

A spokesperson with Colorado Oil & Gas Conservation Commission released the following statement to 9NEWS:

"Absolutely COGCC will look into this, as it would with any similar event. An inspector arrived at the site a while ago."

This is the second fire at this oil well site in the past month. Brighton Fire also responded to a fire at 13448 WCR 4 on Sept. 20. BFD will work with operators and regulators to see why this happened again.

The cause is under investigation.

Brighton Fire was aided by Fort Lupton, North Metro and South Adams Fire Departments.

CORRECTION: Brighton Fire mistakenly called this blaze a fire at a fracking site. They have since issued corrected information saying it was at a well site.
