In 1919, shares in the five surviving Scottish shale oil companies - The Broxburn Oil Company Ltd, The Oakbank Oil Company Ltd, The Pumpherston Oil Company Ltd, James Ross & Company,and Young's Paraffin Light and Mineral Oil Company Ltd - were acquired by a new company, Scottish Oils Ltd, a subsidiary of The Anglo-Persian Oil Company Ltd. The government-backed Anglo-Persian grew into the major multinational company now known as BP. Some of the Scottish shale companies remained active until recent years as operating companies for BP's activities in the North Sea and other areas.
For many years the records of Scottish Oils Ltd, the five companies that they took over, and some of their precursors, were stored at BP's Grangemouth Refinery. This archive included company minute books, ledgers, production statistics, legal agreements and a limited amount of general correspondence. Other paperwork was assembled at the former Pumpherston Refinery, which continued in operation as a detergent plant into the 1990's. This material recorded the operation of the refinery and the activities of the Pumpherston Oil Company Ltd.
