The man who died Saturday at an oilfield worksite near Williston has been identified.
Williams County Sgt. Detective Caleb Fry confirmed the deceased is 34-year-old Jesus Herrera. The Occupational Safety and Health Administration is investigating his death.
An obituary for Herrera said he was an oil field hand for Brigade Energy Services.
Herrera and fellow employees of Brigade Energy Services were reconnecting a heavy rod as they finished servicing a well around 10 p.m. Saturday near Williston when the top end of the rod came loose, fell and struck him in the head, according to an OSHA spokeswoman.
Brigade Energy Services in Williston declined to comment Thursday, citing legal counsel.
Herrera is survived by his parents, two daughters, three sisters and a brother. Funeral services are planned in Kansas.
OSHA has six months to complete its investigation into Herrera's death.
OSHA's last investigation of an oilfield-related fatality in North Dakota was of one in February 2018.
