According to Loving County Sheriff Bill Hopper, the workers were changing a wellhead when a buildup of pressure led to the explosion.
This happened near the Texas' border with New Mexico, sixty miles southeast of Carlsbad New Mexico.
Authorities identified 46-year-old Amos B. Ortega of Artesia, New Mexico and 41-year-old Roberto Magdelino of El Paso, as the persons killed.
Hopper also stated that they initially believed four workers were hurt before the number expanded later in the day.
