Facility Description
The HF Sinclair Navajo Refinery is located in Artesia, New Mexico. According to the company, it is the largest refinery in the state, with a crude oil processing capacity of 100,000 barrels per day. The facility processes crude oil from the Permian Basin, supplying markets in the southwestern United States.
Speculation on Potential Causes

In any refinery incident, investigations typically focus on several potential root causes.

The processing of crude oil involves flammable materials under high pressures and temperatures, creating an environment where an ignition source can lead to a fire or explosion if containment is breached.
