Saudi Aramco's senior vice president for technical services Khalid Al-Buainain has left the company, industry sources said.

Ahmad Al-Sa'adi will take over Buainain's role in the company as acting head for technical services until the end of August this year.

Al-Buainain took early retirement for personal reasons and his departure will take effect on Sunday. He joined Aramco in 1980 and has held several senior positions.

A company spokesperson declined to comment.

In addition to his role as senior vice president for technical services, he was also chairman of PetroRabigh, a joint venture between Aramco and Japan's Sumitomo Chemical.

PetroRabigh said in a statement on Wednesday it had appointed Abdulaziz Al-Judaimi as chaiman of the company following the resignation of Al-Buainain. - Reuters
