(CNN) -- Two workers in Indiana Township, Pennsylvania were killed in a natural gas explosion Friday, officials said.
The blast occurred at approximately 9:50 a.m. ET while crews were working on a well about 15 miles northeast of Pittsburgh, according to Allegheny County spokesman Kevin Evanto.
The explosion sparked a fire, but the once tall flames were brought under control before long, Evanto said.
No other injuries were reported and officials did not order any evacuations.
The names of the victims were not immediately released.
The natural gas well is owned by Huntley & Huntley, which according to its website has over 350 gas wells in the greater Pittsburgh area. The company would only say that workers have been sent to explosion site to investigate.
