Houston-based Apache Energy concluded Wednesday that the murder of an American supervisor in Egypt was an isolated incident.
The Apache worker was shot to death last Wednesday in what appeared to be a carjacking.
His body was found Friday in a car outside Cairo.
Apache spokesman Bill Mintz said the man had worked for Apache for many years, including several years in Egypt as a supervisor of oil and gas production operations.
Apache concluded the incident was isolated but wouldn’t disclose details about the investigation, Reuters said.
The company won’t be releasing the victim’s name.
Initial reports also identified a second victim, a foreigner who worked for Egypt’s government-owned Qarun Petroleum.
Apache didn’t comment on the second victim.
For security reasons the company didn’t disclose if the murdered worker was traveling with a security detail or in a convoy.
Apache has about 140 workers from the U.S. and other nations working in Egypt.
Most of the company’s 9,000 workers in the country are Egyptians employed by joint ventures with Qarun Petroleum and state-owned Khalda Petroleum.
Apache’s oil and gas operations in Egypt’s western desert cover about 10 million acres and produced 198,000 barrels of oil and 912 million cubic feet of natural gas per day in 2013.
