The 1978 annual review of the Arabian American Oil Company (Aramco), published in English only. The report includes a foreword by Ahmed Zaki Yamani, Saudi Arabia's Minister of Petroleum and Mineral Resources, who identifies Aramco's assets, organisation, and staff as three distinct elements contributing to the national wealth of the Kingdom, and notes that 1978 marked a turning point as the Saudi state had effectively owned Aramco since 1 January 1976. Key highlights include: crude oil production averaging 8,066,105 barrels per day, with total annual production of 2,944,128,176 barrels (approximately 17 percent of free world crude production); natural gas liquids (NGL) production reaching a new Company high of 91 million barrels; proved oil reserves of 113.3 billion barrels and probable reserves of 177.8 billion barrels; discovery of three new oil fields — Jaladi and Wariʿah onshore and Harqus offshore — and a deeper-pool gas reservoir in the Hawiyah area of the Ghawar field; workforce rising by over 19 percent to nearly 30,500 from some 40 countries, with Saudi Arabs holding over 41 percent of supervisory positions; and continued progress on the Gas Gathering Programme and Saudi Consolidated Electric Company management. The report also features personal testimonies from representative Aramco employees, including long-serving Saudi and expatriate staff.
