Who we are

Board of Directors

  • Salim Macki, Chairman of OOSC Group of Companies holds a Masters Degree in Petrochemical Engineering from Moscow. He became the first Omani Petroleum Engineer and served as Director General of Oil and Minerals (effectively the Oil Minister).

    Mr. Macki was Ambassador, Government of Sultanate of Oman. He spent most of his working life in the Oil & Gas industry, where he is highly regarded internationally. He holds, or has previously held, many senior executive positions in various private and state owned entities in Oman and internationally.

    It was after Mr. Macki left the Ministry of Oil, that he started his own business in the oil related sector in 1974 - Oman Oilfields Supply Center L.L.C.

    Today, the OOSC Group of Companies has over 8,000 employees and Mr. Macki believes that one of the main reasons behind his success, besides education and opportunities, is the fact that he stayed in the business he knew best.

  • Basil Macki had his early formative years of schooling in the UK. Later, he earned himself a scholarship from Petroleum Development Oman (PDO) to obtain a Master's degree in Mechanical Engineering from the Imperial College of Science, Technology and Medicine, London.
