The objective of this research was to develop a database to store results of laboratory tests of crude oil and this will lead to improve the quality of Petroleum products and to reduce operating cost in the same time. Statistical process control give many tools including the seven quality tools which can be used to determine if the manufacturing process within control limits of crude oil specification and to detect any problem. Using Microsoft Access 2007 program offers many possibilities such as developing database, using statistical tools, building form, query, generating reports, importing and exporting data to statistical program such as Microsoft Excel 2007. Therefore the development of a database with Microsoft Access 2007 will provide electronic data store and using statistical control tools and this will leads to diagnosis problems in production process and improve the quality of petroleum products
